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.
