Letopis is a habit tracker where every day you keep going becomes a journey across a star map. Build a good habit — training, reading, water, meditation — or cut the junk like endless scrolling. It's the same move: mark the day, and your streak grows into a constellation. Not a boring grid of checkmarks, but a living map that shows how far you've come. Every day of yours is set beside a real journey from history — so progress reads as distance behind you, not a fragile number. • One check-in a day — keep the streak and move forward • A living star map instead of a spreadsheet • Miss a day? Your streak isn't wiped — pick up where you left off • A rest day when you need a breather • For building habits and for cutting what drags you down Letopis+ unlocks all stories, removes limits, and supports several habits at once. Payment is charged to your Apple ID, renews automatically, cancel anytime in Settings.

Verdict
The clearest difference is in-app purchases: Doddly at none against Letopis's 3. Doddly also leads on iOS requirement (16.0 vs 26.0). Letopis's advantage is update cadence (every 4 days vs every 5 weeks). On price, ads and device support there is nothing between them.
