# WhoSmarter vs RevLab

The clearest difference is rating: WhoSmarter at 5.0 against RevLab's 3.8. WhoSmarter also leads on ads (none vs shown) and iOS requirement (15.1 vs 17.0). RevLab's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (6 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. WhoSmarter sells 4 in-app purchases, starting at $12.99 per month and RevLab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

WhoSmarter holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: RevLab has 6 ratings behind it against 1, so its average is the more settled of the two.

WhoSmarter ships an update every 3 weeks, RevLab weekly. Both last shipped on October 31, 2026.
