Ninety is in English on iPhone (iOS 17.0 or later).

I could never stick to my resolutions long term. The 90-day structure is ideal: not too long, not too short. Tracking exercise and habits every day is really motivating.

What you get

  1. Your daily contract, built from 99 disciplines

    Choose from 99 disciplines across 10 areas: Physical, Nutrition, Mind, Discipline, Digital, Sleep, Work, Relationships, Finance and Creative. Onboarding builds a daily plan from your goals, your level and the habits you want to break.

  2. Day X / 90 and a streak, on top of every day

    Two counters sit at the top of each day: how far into the 90 days you are, and your current streak.

  3. Hard rules and soft rules

    Hard rules break the streak when you slip. Soft rules just count toward today. You decide which of your disciplines is which.

  4. A soft reset when you miss days

    After three missed days in a row, Ninety offers Pause and Resume (push your end date out and keep your story), Push Through, or Start Over. Your streak stays honest.

  5. Photo proof and a Day 1 vs Day 90 archive

    Photo proof for workouts and weekly progress photos, so you can line up where you started with where you are.

  6. Streak art you can share

    Streak art for TikTok and Instagram in five rotating templates, plus local notifications that nudge you without nagging.

What early testers say

Alex T., early tester

The progress system is really satisfying. You can see your progress week after week. It helped me build a real fitness and mindset routine.

Sophie D., early tester

Clear, engaging challenges. The interface pushes you to go further without guilt-tripping you. I fully recommend it if you want to change your habits!

Questions

Is Ninety an official 75 Hard app?

No. Ninety is an independent 90-day challenge app from EASYTECH. Its App Store listing says it is built on the same psychology as 75 Hard, with the structure to finish. 75 HARD is a separate programme with its own creator and brand.

How long is the challenge?

Ninety is a 90-day program. Every day shows Day X / 90 and your current streak.

What happens if I miss days?

When you have missed three days in a row, Ninety offers three choices: Pause and Resume (your end date moves out and your story keeps going), Push Through, or Start Over.

Can I choose my own daily rules?

Yes. You pick disciplines from 99 options across 10 areas. Hard rules break the streak when you slip; soft rules just count toward today.

Does it track progress photos?

It supports photo proof for workouts and weekly progress photos, with a Day 1 versus Day 90 archive. Photos live in the app's private storage until you choose to export them to your Photos library.

Where is my data stored?

On your device. The listing says there is no cloud sync and no servers holding your progress.

Finish what you start. Day 90 is closer than you think.
