# ABIT vs Interval Timer

The clearest difference is rating: ABIT at 4.8 against Interval Timer's 4.6. ABIT also leads on ratings volume (60 vs 12). Interval Timer's advantage is review sentiment (88% vs 73%) and iOS requirement (13.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ABIT sells 3 in-app purchases, starting at $2.99 per month and Interval Timer sells 3 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

ABIT holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: ABIT has 60 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 73% of ABIT's written reviews are positive against 88% of Interval Timer's, so the app with the better star average is not the one people write more warmly about.

ABIT ships an update every 2 weeks, Interval Timer every 11 days. The most recent releases landed on September 23, 2026 and September 8, 2026 respectively.
