Session continuity
Keep collecting when the Wi-Fi disappears
ABA sessions do not pause because a school hallway, clinic room, or home visit loses signal. TallyFlex keeps data collection available offline, then syncs when the device reconnects.
Use the same trackers, session notes, and active-session workflow across iOS, Android, web, and Chromebook.
Availability: Free, Solo, and Teams
Workflow illustration
Offline is transparent
Collect normally
Tracker taps, timers, notes, mood, and flags keep working during the session.
Save on device
The session stays available locally while the connection is unavailable.
Sync automatically
When the device reconnects, TallyFlex brings the session back into the account workflow.
No separate backup workflow
The point is continuity: keep collecting, then let sync happen when the connection returns.
Workflow
The session keeps moving
Offline mode is built for the moments when the data still matters but the connection is unreliable.
Start the session on the device you have with you.
Collect tracker data, notes, mood, and flags even if the connection drops.
Keep the session record on the device while offline.
Reconnect and let TallyFlex sync the session data back to the account.
Why it matters
Designed for data you can actually review
Collect without a live connection
Session data is saved locally on the device when the internet connection is unavailable.
Sync when connection returns
TallyFlex syncs automatically after the device reconnects, so the session record comes back into the account workflow.
Use the same session flow
Offline mode supports the active-session workflow instead of forcing paper backup sheets.
