# BEAT81 vs TK

The clearest difference is rating: TK at 4.2 against BEAT81's 2.9. BEAT81's advantage is update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ratings volume and ads there is nothing between them.

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

TK holds the better App Store score, 4.2 against 2.9. Both are backed by a comparable volume of ratings — 7 and 6 respectively. Written reviews complicate that: 56% of BEAT81's written reviews are positive against 52% of TK's, so the app with the better star average is not the one people write more warmly about.

BEAT81 ships an update every 3 weeks, TK every 2 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
