# SlimTimer vs GenPad

The clearest difference is ads: SlimTimer at none against GenPad's shown. SlimTimer also leads on iOS requirement (15.0 vs 17.6). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. SlimTimer sells 2 one-off in-app purchases and GenPad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SlimTimer ships an update every 9 days, GenPad fortnightly. The most recent releases landed on October 1, 2026 and October 13, 2026 respectively.
