# Kailo vs Radiantly

The clearest difference is rating: Kailo at 4.6 against Radiantly's 4.1. Kailo also leads on monetization model (ad-supported vs free with in-app purchases) and device support (4 vs 2). Radiantly's advantage is review sentiment (83% vs 50%) and update cadence (every 4 days vs every 9 days). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Kailo sells 1 in-app purchase, starting at $9.99 per month and Radiantly sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Kailo holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 10 and 27 respectively. Written reviews complicate that: 50% of Kailo's written reviews are positive against 83% of Radiantly's, so the app with the better star average is not the one people write more warmly about.

Kailo ships an update every 9 days, Radiantly every 4 days. The most recent releases landed on October 10, 2026 and October 22, 2026 respectively.
