Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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