# Personal Interval Timer vs Lapz

The clearest difference is ads: Lapz at none against Personal Interval Timer's shown. Lapz also leads on rating (5.0 vs 4.8). Personal Interval Timer's advantage is ratings volume (14 vs 1) and iOS requirement (14.2 vs 16.6). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Personal Interval Timer sells 1 one-off in-app purchase and Lapz sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Lapz holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Personal Interval Timer has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Personal Interval Timer ships an update every 4 weeks, Lapz every 2 weeks. The most recent releases landed on September 23, 2026 and October 4, 2026 respectively.
