Verdict
The clearest difference is review sentiment: One at 100% against Timer's 50%. One also leads on rating (5.0 vs 4.4) and in-app purchases (none vs 1). Timer's advantage is update cadence (fortnightly vs every 23 months) and ratings volume (29 vs 4). On price, device support and iOS requirement there is nothing between them.
