# PV Master vs SMTEN

The clearest difference is rating: SMTEN at 4.0 against PV Master's 2.0. PV Master's advantage is update cadence (every 2 months vs every 5 months) and ratings volume (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SMTEN holds the better App Store score, 4.0 against 2.0. Both are backed by a comparable volume of ratings — 3 and 1 respectively. Written reviews complicate that: 14% of PV Master's written reviews are positive against 10% of SMTEN's, so the app with the better star average is not the one people write more warmly about.

PV Master ships an update every 2 months, SMTEN every 5 months. The most recent releases landed on October 17, 2026 and October 10, 2026 respectively.
