Support — Tidemark

Tidemark uses iCloud to sync your data automatically. Make sure iCloud is enabled for Tidemark in your device settings: Settings > Apple ID > iCloud > Apps Using iCloud, and ensure Tidemark is toggled on. Your countdowns will sync across all devices signed into the same Apple ID.

iOS controls how frequently widgets refresh. If a widget appears stuck, try these steps: (1) Open the Tidemark app — this triggers a widget refresh. (2) Remove and re-add the widget. (3) Restart your device. Note that iOS limits widget updates to preserve battery life, so slight delays are normal.

When creating or editing a countdown, select "Weekdays" as the counting mode. By default, this counts Monday through Friday. You can customize which days count as work days. You can also enable holiday exclusion to skip public holidays in your country. Tidemark supports public holidays for 10+ countries.

Yes! Tap the calendar icon to browse your iOS calendar events. You can select any event to create a countdown from it. Tidemark only reads your calendar — it never modifies your calendar events. You'll be asked for calendar permission the first time you use this feature.

Open any countdown's detail view and tap the Live Activity button to start a persistent countdown on your Lock Screen and Dynamic Island. You can have one Live Activity running at a time. To stop it, tap the button again or end it from the Lock Screen.

No. Tidemark is free to download and use with up to 3 countdowns. If you need more, a one-time purchase of $2.99 unlocks unlimited countdowns forever. There are no subscriptions, no recurring fees, and no ads. All future updates are included.

All your data is stored on your device and in your iCloud account. To delete everything: (1) Delete the app to remove local data. (2) Go to Settings > Apple ID > iCloud > Manage Storage to remove iCloud data. We have no servers and no copies of your data. See our Privacy Policy for more details.

Please email us at kontakt@nexolab.pl with a description of the issue, your iOS version, and your device model. Screenshots or screen recordings are very helpful. We typically respond within 24 hours.
