# Pre vs One Timer

The clearest difference is in-app purchases: Pre at none against One Timer's 4. Pre also leads on device support (3 vs 1) and iOS requirement (14.0 vs 17.6). One Timer's advantage is ads (none vs shown) and update cadence (every 4 days vs every 7 months). On price there is nothing between them.

Both are free to download. One Timer sells 4 in-app purchases, starting at $1.99 per month. Pre asks for nothing beyond the download.

Pre ships an update every 7 months, One Timer every 4 days. The most recent releases landed on September 22, 2026 and September 17, 2026 respectively.
