# Interval Timer vs ABIT

The clearest difference is ads: ABIT at none against Interval Timer's shown. ABIT also leads on rating (4.8 vs 4.5). Interval Timer's advantage is ratings volume (19K vs 60) and iOS requirement (13.0 vs 17.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and ABIT sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ABIT holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 60, so its average is the more settled of the two. Written reviews point the same way: 69% of Interval Timer's written reviews are positive against 73% of ABIT's.

Interval Timer ships an update every 9 days, ABIT every 2 weeks. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
