Miss a day. Nothing resets. Continuum is the habit tracker for consistency, not perfection: one number per habit, the share of days you actually showed up over the last 66. It's free. There's nothing to sign up for and nothing to buy. THE NUMBER Streaks are brittle. One bad Tuesday and six weeks read 0, which is usually the day people quit. I built this app around streaks for a year, freezes included, and it was the wrong number to put in front of anyone who was mostly doing fine — the person who misses one Tuesday in six weeks is exactly the one a reset loses. Here a missed day is a dip: a point or two once a habit is a couple of months old, more while it's new. Show up tomorrow and it climbs back. The count starts on your first day. A habit you began last week isn't scored against the weeks before it existed. GETTING MORE CONSISTENT Every number has a triangle beside it: how far it moved this week. The stats screen draws your last 12 weeks as bars, one per week, so you can see whether you're getting better — which matters more than whether you're perfect, because almost nobody is. NEVER MISS TWICE It's James Clear's rule. Missing once is normal; the trick is not letting one miss turn into two. With reminders on, a missed day gets one quiet nudge the next evening. Mark it and the card says you're back on it. 66 DAYS, MOST OF THEM In a UCL study (Lally et al., 2010), daily habits took a median of 66 days to become automatic — 18 for some people, 254 for others — and one missed day didn't materially slow it down. A 2024 review of 20 studies says to plan on two to five months. So a habit here is formed after 66 days with at least 80% of them done. The 80% is my line for "most days"; neither paper sets one. THE GRID Every habit gets a 66-day grid, one square per day. Your number is exactly the filled squares over the squares so far. MARKING DONE Press and hold. Haptics build under your thumb and release when the day registers (hard to do by accident). Forgot yesterday? Tap once, then hold. WIDGETS Home screen and lock screen, percentage included. On the home screen, mark a habit done without opening the app. THE REST A year heatmap per habit. Share cards. iCloud sync across your devices. Dark, monospaced, deliberately plain. There's no social feed, and nothing resets.

STRIK is the streak tracker built on real habit science. Your body doesn't lose a habit after 1-2 days off, so why should your streak? Build lasting streaks for reading, exercising, meditating, or any habit you want to develop. This streak tracker understands how habits actually work. - Science-based Freeze system respects your body's adaptation - Visualize all your streaks at a glance - 100% private streak tracker, no account needed - Realistic approach to building lasting habits - Minimalist design that stays out of your way FREEZE SYSTEM - BASED ON HABIT SCIENCE Here's the truth: Missing 1-2 days doesn't break your habit adaptation. Your body and brain retain the habit for short breaks. STRIK gives you Freezes at 7 days and 21 days. Use a Freeze when life happens - your streak stays alive because your habit adaptation is still intact. But skip multiple days in a row? Your streak resets. Why? Because that's when your body actually loses the adaptation. No fake streaks here. The only streak tracker that reflects how habits actually form in your body and mind.

STRIK is based on science: Your body retains habit adaptation for 1-2 days. That's when you earn Freezes (at 7 and 21-day milestones). But skip 3+ days consecutively? Your streak resets because your adaptation is actually gone. Real habits. Real science. No fake progress. JOIN 5000+ USERS Join hundreds of people maintaining their streaks with STRIK!

Verdict
The clearest difference is in-app purchases: Continuum at none against STRIK's 4. Continuum also leads on ratings volume (6 vs 1). STRIK's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price, rating and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. STRIK sells 4 in-app purchases, starting at $3.99 per month. Continuum asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for Continuum against 5.0 for STRIK. That said, the two scores are not equally well evidenced: Continuum has 6 ratings behind it against 1, so its average is the more settled of the two.
