Get in touch

Write to us: Email us. It helps to say which device you use (iPhone, Apple Watch or both) and what you expected to happen. We answer every message, usually within a few days.

Restore your purchase

The optional unlock for History and Stats older than 30 days is tied to your Apple Account, so you never buy it twice. On a new iPhone, or after reinstalling:

• open Today → More (the ••• button) → About, and tap Restore Purchases; or
• open History or Stats and tap Restore Purchases on the unlock card.

Family Sharing is on: family members in your Apple family group get the unlock too.

Delete your data

Everything stays on your devices until you delete it. We hold no copy.

• One entry: delete it in the app’s History.
• Everything on a device: delete the app from that device. The iPhone and Apple Watch apps keep their own copies, so delete the app on both.
• Copies in device backups: these remain until those backups are replaced or deleted.

What you can say to Siri

No setup needed, on iPhone and Apple Watch. Siri replies with facts only, such as the time elapsed or the time to your goal.

• “Start my fast in Ottan”
• “Start a 16-hour fast in Ottan” 12, 14, 16, 18, 20 or 24 hours, for that fast only
• “End my fast in Ottan”
• “How long have I been fasting in Ottan”
• “I’m up in Ottan” marks when you woke, for Morning Light
• “Start morning light in Ottan”
• “Start my walk in Ottan”
• “Start my wind-down in Ottan” Dim Evening
• “Good night Ottan” ends the wind-down
• “Log a coffee in Ottan” the same drink as last time
• “I had a latte in Ottan” or an espresso, a tea, any drink in the list
• “When is my last coffee in Ottan” the latest that still fits your bedtime

You can also run any of these from the Shortcuts app, or put one on the Action button.

Dim Evening and Sleep Focus

Apps can’t turn on a Focus. In the app, Dim Evening → Turn on Sleep Focus too offers the shortcut “Dim Evening and Sleep”: it starts your wind-down, then turns on Sleep Focus. Say it to Siri or put it on the Action button. Your Apple Watch follows the Focus on your iPhone.

If you use a sleep schedule, you can do it the other way round: in Shortcuts, add a personal automation “When Wind Down begins → Start Dim Evening”.

Is this medical advice?

No. Ottan is a wellbeing and habit app. It provides general information, not medical advice, and is not a medical device: it does not diagnose, treat or prevent any condition. Fasting is not suitable for everyone. If you have diabetes or take glucose-lowering medication, are pregnant or breastfeeding, are under 18, have a history of disordered eating, or have any medical condition, talk to a clinician before you start.
