FlexChallenge vs Streaks
Updated October 4, 2026
Streaks and FlexChallenge both put a daily checklist on your iPhone. The difference is what happens over time. Streaks counts up forever. FlexChallenge gives every goal a Day 1 and a finish line, plus the programs, task types and proof you need to get there.
Why people switch from Streaks to FlexChallenge:
- Challenges that end: commit to 30, 75 or 365 days and actually finish.
- Ready-made programs: 75 Days Phase I–III, 75 Soft, Core 4 and more, set up in a minute.
- Proof of progress: daily photos, video clips and voice notes.
- Strict or flexible: choose whether a missed day means starting over.

Streaks never end. Challenges do.
A streak has no finish line. The longer it runs, the more it hurts to break, until keeping the number alive matters more than the habit. And there's never a day when you're done.
A challenge is different. You commit to 30, 75 or 90 days and you know exactly when it ends. That makes harder goals easier to start, gives you a real win at the end, and lets you choose what comes next. FlexChallenge is built around that loop: start, finish, stack the next one.

- Proof of progress in one gallery: see Day 1 next to Day 75.
- Strict mode for 75 Hard-style rules, or flexible mode when life happens.
- Stats that matter for a challenge: completion rate, streaks, personal bests and trends across every challenge you run.
- Privacy: no account, no ads, no tracking, and no cloud copy of your photos.

Frequently asked questions
Is FlexChallenge a good Streaks alternative?
Yes. FlexChallenge does daily check-offs like Streaks, and adds challenges with a set end date, ready-made programs like 75 Hard-style Phase I and 75 Soft, progress photos and voice notes, and a choice of strict or flexible mode.
What's the difference between a habit tracker and a challenge tracker?
A habit tracker counts an open-ended streak. A challenge tracker like FlexChallenge gives each goal a Day 1 and a final day, so you commit to a fixed period, see how far along you are, and finish.
Can Streaks track 75 Hard?
You can create the five tasks in Streaks yourself, but it doesn't count down to Day 75, store progress photos, or ask you to restart when you miss a day. FlexChallenge does all three with its 75 Days: Phase I template.
How much does FlexChallenge cost?
$3.99/month or $24.99/year, with a 14-day free trial on either plan. No account and no ads.
