# Metric vs THTC +

The clearest difference is rating: Metric at 4.0 against THTC +'s 3.5. Metric also leads on update cadence (weekly vs every 10 months) and ratings volume (45 vs 2). THTC +'s advantage is in-app purchases (none vs 16) and iOS requirement (14.1 vs 18.1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Metric sells 14 in-app purchases, starting at $10.99 per month. THTC + asks for nothing beyond the download.

Metric holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: Metric has 45 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 53% of Metric's written reviews are positive against 50% of THTC +'s.

Metric ships an update weekly, THTC + every 10 months. The most recent releases landed on October 25, 2026 and October 16, 2026 respectively.
