# Kai vs LimitLess

The clearest difference is review sentiment: LimitLess at 71% against Kai's 0%. LimitLess also leads on update cadence (every 3 days vs every 3 weeks) and ratings volume (7 vs 2). Kai's advantage is rating (4.5 vs 3.9). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kai sells 4 in-app purchases, starting at $4.99 per 7 days and LimitLess sells 2 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Kai holds the better App Store score, 4.5 against 3.9. Both are backed by a comparable volume of ratings — 2 and 7 respectively. Written reviews complicate that: 0% of Kai's written reviews are positive against 71% of LimitLess's, so the app with the better star average is not the one people write more warmly about.

Kai ships an update every 3 weeks, LimitLess every 3 days. The most recent releases landed on August 18, 2026 and September 14, 2026 respectively.
