Common questions

My streak count looks wrong

Open the app once a day around midnight to be sure the counter has rolled over. If you traveled across time zones, the count uses your device's current time zone — change it in iOS Settings if needed.

I missed a milestone notification

Notifications fire at 9:00 AM local time on the milestone day. If you opened the app the same day after the notification, the in-app celebration screen will still appear. If you opened it days later, it will appear the next time you open the app — once per milestone.

I need to change my start date

Tap the gear icon → Start date → pick the new date → Save. This recalculates your streak and reschedules upcoming milestone alerts.

I want to start over

Main screen → "Start over" at the bottom → confirm in the sheet. Your previous best is saved and shown on the confirmation sheet. Day count resets to 0.

The widget isn't updating

Long-press the widget → Edit Widget → close. Or remove and re-add it from the home screen. If that doesn't work, restart your iPhone.

How do I count more than one thing?

Counters tab → "Add a count". Give it a name and the date it started — the date can be in the past. Each count keeps its own milestones and can have its own widget. On the main screen, swipe sideways to move between them.

How do I see the money I haven't spent?

For your first count: Settings → Weekly spend. For any other count: Counters tab → tap the count → Edit → Money → Weekly spend. Enter roughly what it used to cost you in a week; the count then shows what you haven't spent since you started. Leave it empty to turn it off. Each count keeps its own amount.

I paid but it still says I need to buy it

Tap "Restore purchase" — it's on the offer screen and in Settings. That asks Apple what you already own and unlocks it again. It's free, works on any device signed into the same Apple Account, and works after reinstalling. If it still doesn't unlock, check you're signed into the same Apple Account you bought it with, then email us.

Can I get a refund?

Refunds are handled by Apple, not by us — we never see your payment and can't issue one. Go to reportaproblem.apple.com, sign in, and choose the purchase. If it's refunded, nothing is deleted: your extra counts become read-only and stay yours to remove.

Is it a subscription?

No. One payment, once. Nothing renews and there's nothing to cancel.

How do I delete my data?

There's nothing to delete on a server — Kern stores everything locally on your iPhone. Uninstalling the app removes all of it. There is no account to close.
