app2dat for members
Everything you need as a member: create an account, join your club, chat, keep track of sessions and attendance, pay fees. Step by step — for reading up and looking things up.
What is app2dat?
app2dat connects you with your clubs, associations and communities. The core idea: One profile. All your clubs. You maintain your data exactly once — and share it selectively with the organizations you belong to. If your phone number changes, you change it in one place; all your clubs are up to date instantly.
- One profile, many clubs: Your master data belongs to you. You decide per group who sees what.
- Real-time communication: Group chats, private messages, surveys and announcements — instantly on all devices.
- Sessions & attendance: Trainings, courses and events in your calendar; sign up or off with one tap.
- Fees: View membership fees and pay them right in the app.
- Everywhere: As a web app in the browser and as an app for Android, iOS and Windows — always in sync, usable offline too.
Family-friendly: One account can hold several profiles — your own, your children's, and even organization profiles you manage.
Installation & account
Install the app
The fastest way: the web app at m.app2dat.com — it runs right in the browser, no installation required. For the best experience, install it as an app (PWA):
- Open m.app2dat.com in your browser.
- On the start page tap Install app. In Chrome, Edge and on Android the installation starts right away; on iPhone the guide shows you the way via the share icon → Add to Home Screen.
- From then on app2dat starts like a normal app from your home screen.
Important for push notifications: In the browser, notifications only work reliably in the installed app. The native apps for Android, iOS and Windows are coming to the stores soon.
Create an account
- On the sign-in page choose Register new user account.
- Enter your email address and a password (at least 8 characters, with upper and lower case, digit and special character) and accept the terms of use.
- You will receive an activation email — activate the account via the link inside, done.
Alternatively, sign in without a password of your own with Google or Apple — the buttons are right on the sign-in page.
Signing in & forgotten password
Email and password are all you need to sign in. If you forgot your password, choose Forgot password — you receive a recovery email and set a new password yourself.
Two-factor sign-in (2FA): If you have enabled 2FA (see Settings & security), every sign-in additionally asks for a 6-digit code sent to you by email.
Registration via a club link
Many clubs invite via a link or QR code (notice board, website, message). Following such a link, a form guides you through registration: account (email/password), profile data (first name, last name, gender, date of birth) and optionally address and phone. For minors a legal guardian is recorded as well — app2dat automatically creates a separate profile for them as contact person. If the group is protected, the form asks for the group PIN your club gives you.
The app at a glance
After signing in you land on the start page. It shows three areas:
- Manage profiles — all your profiles as round avatars: your personal one, your children's, your organizations. A number badge shows unread notifications, a green checkmark the verification status. Tapping opens the profile.
- Today's events — your sessions of the day as cards with time and group.
- Announcements and posts — the feed of your clubs: the digital notice board (see Stories & feed).
Navigation
- ☰ Hamburger menu (top left) — opens the profile list for quick profile switching. There are no settings here.
- User menu (top right) — new profiles, language, theme, security, info and logout (see Settings).
- AI Assistant — the help bot as a side panel, answers questions right in the app (see AI Assistant).
Your personal profile has five tabs
| Tab | What you find there |
|---|---|
| Registered | All groups and events you are registered with — including status and search. |
| Search | Find public organizations, groups and events — by location, date and category. |
| Notifications | Invitations, news, private messages and your contacts. |
| Sessions | Your weekly calendar across all clubs. |
| Profile | Your master data, profile ID with PIN and QR code, verification. |
Profiles
One account can hold several profiles. A personal profile represents a person; an organization profile represents a club (more on this in the Administration Manual).
Create a new profile
- Open the user menu at the top right.
- Choose New person (or New organization for a club).
- Enter a name, optionally a profile picture — done. The app switches straight to the new profile.
Child profiles
For children you simply create another personal profile under your account. You manage it alongside yours; a contact person (e.g. you as legal guardian) can be stored in the profile. That way you sign your child up for training with two taps — without a separate account.
Edit your profile
In the Profile tab you maintain your profile picture, master data (name, title, gender, date of birth), contact details and address. In addition:
- Interests — control which events and suggestions match you.
- Contact persons — e.g. the contact person of a child profile.
- Check location — validates your address for distance search and nearby events.
Your profile ID + PIN: In the profile tab you find your profile ID (P…) with PIN and QR code. A club uses it to add you directly as a member — show the QR code at the desk, scan, done.
Data sovereignty: Each group only sees the fields it really needs and that you share. If you leave, the club's access to your data ends.
Joining clubs & groups
There are four ways into a group — pick the most convenient:
Scan a QR code
In the Search or Registered tab tap the QR symbol and scan your club's invitation QR. Group and provider are displayed — join with Register.
Enter group code + PIN
In the same dialog you can type the group ID (format "G…") and the PIN by hand instead of scanning — your club gives you both.
Search & register
The Search tab finds public groups and events — filterable by text, date and distance. Tapping opens the info with participation conditions; choose Register there.
Accept an invitation
If a club invites you directly, the invitation appears in the Notifications tab — accept or decline, done.
Understanding the status: Depending on the group settings your join is either active immediately or waits as requested for approval by the management. Unregistering may require confirmation too. You always see the current status in the Registered tab.
Using groups
When you open a group you see a tab bar. Which tabs appear depends on the group type:
- Chats — the group's conversation topics, read and join in.
- Tasks — task list with priorities and due dates.
- Content — shared documents, folders and links.
- Group data — your data fields for this group (see next chapter).
- Participants — the member list, if the club has enabled it.
- Sessions — the session calendar (event groups only).
A bell icon next to chats, tasks and topics switches notifications for exactly that element on or off.
Group types: Standard groups bundle communication and content. Event groups additionally have session management with attendance — typical for training groups and courses.
Filling in group data
Each group can define its own data fields — for example phone number, clothing size, belt grade or the membership fee. This is the heart of "maintain data once": the club only asks for what it really needs, and you fill it in yourself.
The Group data tab shows all fields of the group:
- Editable fields you fill in directly — text, number, date, time, yes/no or a choice from a list.
- Read-only fields were made visible for you by the management (e.g. your grading).
- File fields: Upload requested documents (e.g. a medical certificate) or open provided files.
- Payment fields show your fee status: open (red) or paid (green) — tapping opens the payment (see Paying fees).
The small info icon on a field shows the club's explanation of what to enter.
Group chat
Communication is organized by topics — such as "General", "Training" or "Questions". That keeps every conversation findable.
Writing messages
Open a topic, type your text, send . Via the paperclip you attach content:
- upload a file or image,
- insert a link (with preview),
- create a survey (see next chapter).
Reacting to messages
Tap a message — the action menu offers, depending on the situation:
- add an emoji reaction (reactions appear below the message),
- copy text, download attachment,
- edit or delete your own messages,
- Seen by — who has already read the message,
- start a private message to the author.
Announcements: The management can mark messages as announcements — they additionally appear as a post in the feed on the start page, so nothing gets lost.
Surveys
Surveys run right in the chat: "Who's coming to the tournament on Saturday?" — vote with a tap on the answer option in the message.
- Depending on the settings, one answer or multiple answers are possible.
- In anonymous surveys only counts are shown, no names.
- If "delay result" is active, you only see the results after voting yourself.
- A locked survey is closed — voting is no longer possible.
Open the results via the action menu of the survey message (Survey results).
How to create a survey yourself is described in Group chat: paperclip → Create survey — choose question, answer options (optionally with emoji) and settings, send.
Messages & contacts
The Notifications tab in your profile bundles everything personal — the badge shows the unread count.
Notifications
- Invitations to groups and events — accept or decline directly.
- Latest: new topics, tasks, status changes and private messages.
- Delete single entries or clear everything at once.
Private messages
Direct messages are only visible to you and the other person. You start them from a group's member list, from the chat (action menu of a message) or from your contact list. Attachments, emoji reactions plus editing and deleting your own messages work here too.
Pinning & blocking contacts
- Pin: The pin symbol in the private chat remembers the contact in your contact list.
- Block contact: Via the menu in the private chat — the person can no longer send you messages. You find (and unblock) blocked contacts via Show blocked.
Sessions & attendance
The Sessions tab shows your weekly calendar across all clubs — colored cards per group, today is highlighted. Your sessions of the day are also right on the start page.
What you can do in the calendar
- Browse the weeks with the arrows, jump back with Today.
- Filter by group and show hidden sessions again.
- Tap a session for details and actions.
Signing up and off
Via Register/Unregister in the session you sign up or off — with an optional comment (e.g. "15 minutes late"). Once the session has started, the entry is closed.
Attendance by QR
At many clubs you simply check in at the entrance with your profile QR code (profile tab) — the coach scans, your attendance is documented.
Cancellations: If a session is cancelled you see the cancellation with the reason right on the session — and you are notified.
Tasks
The Tasks tab of a group shows what needs doing — from the bake sale to washing the jerseys. Every task shows:
- priority (icon),
- due date with date and time,
- status (open, in progress, done),
- the recorded effort.
Tap a task to open its task chat — ask questions and comment on progress there. The bell controls notifications per task.
Documents & content
In the Content tab your club provides material — neatly organized in folders:
- Documents — view and download PDFs, images and other files.
- Folders — nested structure, navigate with the back arrow.
- Links — external web addresses with preview; open or copy via context menu.
The search field helps you find content again quickly.
Paying fees
Membership fees appear as payment fields in the group data: open (red) or paid (green). An open fee can be settled right in the app:
- Open the group → Group data tab → tap the open amount.
- Choose your payment method:
- Pay with PayPal — PayPal or card payment (if the club offers it),
- Copy IBAN — transfer the classic way yourself,
- Subscribe with PayPal — pay recurring fees automatically (cancel anytime).
- Need a receipt? Download PDF provides the document for the fee.
Recurring fees (e.g. monthly) automatically create a new payment request when due. If you pay cash or by bank transfer, the management books the receipt — the status turns green.
Stories & feed
The "Announcements and posts" feed on the start page is your clubs' notice board: news, photos, event announcements and shared links.
Create your own story
- Tap the on the feed on the start page.
- Write your text; optionally add a photo, link, categories and location; allow or disable comments.
- Save — the story appears for the members of your groups and stays visible for one year by default.
React & manage
- Emoji reactions and comments (if allowed) below every post.
- The feed can be filtered by group, searched in full text and narrowed by date.
- Via a story's context menu: edit, delete, share your own posts — hide or report others'.
Verifying your profile
Verification confirms your real identity — your profile then carries a green checkmark. That builds trust in the club and is the foundation of verified communities.
- Open your profile → Profile tab → Verify now.
- Confirm your master data (first name, last name, date of birth, ID number).
- Purchase the verification and start the ID check: a guided scan of your ID with face matching via the certified service Didit.
- The result comes back automatically — on success your profile is verified.
| Verification | Cost | Validity |
|---|---|---|
| Person | €15.00 / year | 1 year each, renew afterwards |
| Child under 16 | free | |
| Organization | €55.00 / year |
Child profiles: The confirmation is done by the legal guardian; for children under 16 verification is free. If the automatic check fails, you can request a manual review by the app2dat team.
AI Assistant
The robot icon at the top right opens the AI Assistant — your built-in help. It knows exactly which page you are on and answers in your language.
- Ask questions: "How do I sign my child up for training?" — the assistant explains the steps.
- Show elements: It highlights the matching buttons right in the app — the most important element lights up automatically after the answer.
- Tutorials: For common questions it suggests ready-made step-by-step guides — instantly, without waiting.
- Run solutions: If a prepared automation exists for your request, it offers to run it at the press of a button.
This manual is the alternative to the assistant — both are based on the same knowledge. Simply use whichever suits you better.
Settings & security
Everything personal about your account lives in the user menu at the top right — the signed-in email address is shown at the top.
| Menu item | Function |
|---|---|
| New person / New organization | Create another profile under your account. |
| Privacy | Change password, two-factor authentication, devices, local data (details below). |
| Language | System language (automatic), German or English. |
| Theme | Light, dark or system setting. |
| Info | App version, terms of use, privacy policy, homepage. |
| Logout | Signs out this device. |
Security in detail
- Change password: Before every change a confirmation code is sent to your email — only then do you set the new password.
- Two-factor authentication (2FA): The switch under Privacy enables the additional email code at every sign-in. Recommended!
- Log out other devices: Ends all sessions except the current one — handy after switching or losing a device.
- Delete local database: Clears the offline cache on this device; your data stays on the server.
Keeping the web app up to date
In the web app the Info dialog compares your version with the current server version. If an update is available, a tap on Update is all it takes. If the web app ever hangs, Clear app cache in the user menu helps. The native apps update via the stores.
Legal texts: When the terms of use or privacy policy change, the app asks for your consent at startup — with links to both texts.
Help & support
AI Assistant
The fastest help right in the app: ask a question, get an answer with highlighted buttons — around the clock.
Club questions
Questions about your club's fees, sessions or groups are answered by your club's management — e.g. via private message.
