# Interval Flow vs 1% Habit

The clearest difference is price: Interval Flow at Free against 1% Habit's $0.99. Interval Flow also leads on rating (4.7 vs 4.5) and ratings volume (168 vs 13). 1% Habit's advantage is review sentiment (80% vs 48%) and update cadence (weekly vs fortnightly). On ads, in-app purchases, monetization model and device support there is nothing between them.

Interval Flow is free to download; 1% Habit costs $0.99 up front. Interval Flow sells 10 in-app purchases, starting at $4.99 per 3 months and 1% Habit sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Interval Flow holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Interval Flow has 168 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 48% of Interval Flow's written reviews are positive against 80% of 1% Habit's, so the app with the better star average is not the one people write more warmly about.

Interval Flow ships an update fortnightly, 1% Habit weekly. The most recent releases landed on October 15, 2026 and October 6, 2026 respectively.
