# TENS! vs Mastermine

The clearest difference is ads: Mastermine at none against TENS!'s shown. Mastermine also leads on update cadence (every 3 weeks vs every 4 months) and review sentiment (73% vs 61%). TENS!'s advantage is ratings volume (20K vs 116). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. TENS! sells 15 in-app purchases, starting at $5.49 per 7 days and Mastermine sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

TENS! holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: TENS! has 20K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 61% of TENS!'s written reviews are positive against 73% of Mastermine's, so the app with the better star average is not the one people write more warmly about.

TENS! ships an update every 4 months, Mastermine every 3 weeks. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
