# PRO vs Prolab Smart

The clearest difference is review sentiment: Prolab Smart at 100% against PRO's 30%. Prolab Smart also leads on iOS requirement (11.0 vs 16.0). PRO's advantage is update cadence (every 3 weeks vs every 20 months) and rating (4.9 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

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

PRO holds the better App Store score, 4.9 against 4.6. Both are backed by a comparable volume of ratings — 107 and 27 respectively. Written reviews complicate that: 30% of PRO's written reviews are positive against 100% of Prolab Smart's, so the app with the better star average is not the one people write more warmly about.

PRO ships an update every 3 weeks, Prolab Smart every 20 months. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
