Build a routine you want to return to. KeepFlame brings habits, to-dos and a growing card collection together on your iPhone. MAKE TODAY COUNT Create daily habits or choose specific weekdays.

TURN PROGRESS INTO A COLLECTION Start with a welcome gift of 10 Ember. Complete all of today's scheduled habits to earn 10 more, with another 10 for every 7 consecutive perfect days. Each draw costs 10 Ember and reveals a card you do not yet own. Collect all 22 illustrated cards, with no duplicates during a collection. To-dos do not earn Ember. Ember cannot be bought, traded or redeemed for money. Cards are for collecting and sharing. No fortune-telling features are included.

Browse your Collection, open a card to see its details and share its image through the iOS share sheet.

Oath

Read full description

Most habit apps let you lie to yourself. Oath doesn't. With Oath, you commit to your daily habits and tasks โ€” then prove you did them. Using your camera and AI verification, Oath holds you to the standard you set for yourself. No checkbox cheating. No skipped days you pretend didn't happen. PROVE IT Snap a photo as proof of what you completed. Our AI reviews it instantly and validates your effort โ€” so "done" actually means done. You get three attempts per item to keep things fair, but honest. OR JUST TICK IT Not every promise needs a photo. Choose manual check-off for the habits and tasks you'd rather mark yourself. You decide how you hold the line. STREAKS THAT MEAN SOMETHING Your streak only grows when you actually show up. Complete your day and it builds. Skip a day you had tasks on, and it breaks. Simple. Real. Motivating โ€” with milestone celebrations as it climbs. BUILD GOOD HABITS. QUIT BAD ONES. Set habits to build โ€” a morning run, reading, the gym โ€” or habits to quit, like no scrolling or no alcohol, and track your clean days. Flexible schedules let you commit every day, on weekdays, weekends, or custom days. BUILT FOR YOUR ROUTINE - Recurring habits with flexible schedules - One-off daily oaths for the things that matter today - Photo-proof validation powered by AI โ€” or manual check-off - Streak tracking with milestone celebrations - Daily reminder notifications YOUR DATA, PROTECTED Sign in with Apple to sync across devices and protect your streak. All your data is encrypted and secured. The only app that makes you prove it. Start your streak today. This app is a paid product. Both monthly and yearly subscriptions are available, with a free trial on the yearly. Privacy Policy - https://www.oath-app.com/privacy Terms of Service - https://www.oath-app.com/tos
