# Simple Training Timer vs AI Scale

The clearest difference is review sentiment: Simple Training Timer at 70% against AI Scale's 14%. Simple Training Timer also leads on ratings volume (63 vs 1) and update cadence (every 3 weeks vs every 3 months). AI Scale's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Simple Training Timer sells 1 in-app purchase, starting at $1.99 per month. AI Scale asks for nothing beyond the download.

AI Scale holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Simple Training Timer has 63 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of Simple Training Timer's written reviews are positive against 14% of AI Scale's, so the app with the better star average is not the one people write more warmly about.

Simple Training Timer ships an update every 3 weeks, AI Scale every 3 months. The most recent releases landed on September 24, 2026 and September 16, 2026 respectively.
