# i.Timer vs IntervalTimer(x)

The clearest difference is in-app purchases: IntervalTimer(x) at none against i.Timer's 1. IntervalTimer(x) also leads on ads (none vs shown) and rating (5.0 vs 4.7). i.Timer's advantage is ratings volume (29 vs 1) and update cadence (weekly vs every 3 weeks). On price and device support there is nothing between them.

Both are free to download. i.Timer sells 1 one-off in-app purchase. IntervalTimer(x) asks for nothing beyond the download.

IntervalTimer(x) holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: i.Timer has 29 ratings behind it against 1, so its average is the more settled of the two.

i.Timer ships an update weekly, IntervalTimer(x) every 3 weeks. The most recent releases landed on September 21, 2026 and July 6, 2026 respectively.
