Verdict
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.
