If something is wrong
Is it free?
Yes, the core is free. Signing in is optional: without it everything stays on this device.
Reminders don’t arrive
Open Settings › Reminders: turn on “Get reminders”, choose “Where to send” and tap “Test”. If reminders go to Telegram, the bot must not be stopped.
I don’t see shifts, classes or tasks in the calendar
Check Calendar › “Calendars” › “Show”. If the whole section is missing, turn it on: Settings › Tab bar.
The shift alarm doesn’t ring
The shift alarm works only in the Android and iPhone apps. Turn it on in Settings › Reminders › “Shift alarm”, set “Wake me at” in the ready shift and tap “Test the alarm”.
My entries aren’t on my other device
Sign in the same way on both devices: Settings › Account and sync. Without signing in, entries stay only where you made them.
How to move data from another app
Settings › Account and sync › “Import from another app”: calendars, contacts, Daylio, Todoist and others, and any spreadsheet.
The new version didn’t show up
Close the app and open it again. If that doesn’t help: Settings › About › “Update the app”.
The bot doesn’t answer in the group chat
Use /dz or reply to the bot’s message. To make it understand ordinary messages, turn on “Understand messages” in the chat’s /settings.
