Happies is the to-do app that actually makes you want to do your to-dos. Most to-do apps just store your tasks. Happies helps you prioritize them. You rate each task by urgency and importance — Happies automatically sorts them into four clear buckets, so you always know exactly what to work on next. DO IT NOW — urgent and important. Handle these today. DEEP WORK — important but not urgent. Schedule focused time. UPCOMING — delegate or do later. FOR LATER — park it here. Every task you complete earns XP. Level up. Build momentum. Watch your Done List grow. Say goodbye to Sunday Scaries and hello Sunday Happies! $4.99 unlocks unlimited tasks forever — or try free with up to 5 tasks. No ads or subscriptions.

What is habit stacking? Habit stacking is a proven productivity technique that pairs a new, desired behavior with an existing, automatic daily routine. By using an established habit as a natural trigger, you bypass the need for relying on willpower, making it significantly easier to build consistent routines. After I pour my morning coffee, I will write down my top priority for the day. The coffee is the trigger; the new habit stacks right on top. How the app works? 1. Add a habit and the date you started it. 2. Keep your streak — the app tracks how many days you've kept each habit. 3. Watch habits level up as streaks pass 1, 21, and 365 days.

Verdict
The clearest difference is in-app purchases: Habit Stacker App at none against Happies's 1. Habit Stacker App also leads on update cadence (every 2 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
