By 2026, the app store landscape has become flooded with "75 Challenge" trackers. Some are brilliant, minimal tools that keep you accountable. Others are battery-draining ad farms. Finding the right digital companion can make the difference between a forgotten streak and a completed challenge.
We've tested the top contenders on both iOS and Android to bring you this curated list. Whether you want a dedicated 75 Soft interface or a powerful general habit tracker, here are the best apps to help you cross the finish line this year.
Dedicated 75 Soft Trackers
These apps are built specifically for the challenge, pre-loaded with the four main rules.
1. 75 Soft Challenge: 75 Days (Winner: Best Overall)
The gold standard for dedicated tracking. It comes pre-configured with the standard 75 Soft rules but—crucially—allows for the small customizations that make "Soft" sustainable.
- Pros: Zero setup required, built-in progress photo gallery, simple interface.
- Cons: The free version has ads; pro version unlocks stats.
- Price: Free / $4.99 Pro Lifetime.
2. The "Hard 75" App (Modified)
While initially built for the harder challenge, many developers have added a "Soft Mode" toggle in 2026 updates.
- Pros: Robust community features, very stable.
- Cons: UI can feel aggressive (red/black themes) which might clash with the gentler Soft vibe.
- Price: Free with IAP.
Best General Habit Trackers
Sometimes the best app isn't a niche tracker, but a polished habit tool you configure yourself.
1. Streaks (iOS Essential)
Still the most beautiful habit tracker on the App Store. You can set up exactly four tasks: "Eat Well," "Train 45m," "Drink 3L," and "Read 10 Pages." The icons are gorgeous, and it syncs flawlessly with Apple Health.
Why We Love It
It has zero clutter. Tapping the big circle to complete a task feels incredibly satisfying. It's paid, but worth every penny for the design alone.
2. Habitica (For Gamers)
If you need external motivation, Habitica turns your 75 Soft challenge into an RPG character. Missing a workout deals damage to your avatar; completing 75 days levels you up.
