Verdict
The clearest difference is price: Only One at Free against Radiant's $2.99. Only One also leads on update cadence (weekly vs every 3 months) and ratings volume (6.3K vs 99). Radiant's advantage is in-app purchases (none vs 10) and ads (none vs shown). On review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Only One is free to download; Radiant costs $2.99 up front. Only One sells 10 one-off in-app purchases. Radiant asks for nothing beyond the download.
Radiant holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Only One has 6.3K ratings behind it against 99, so its average is the more settled of the two. Written reviews complicate that: 83% of Radiant's written reviews are positive against 88% of Only One's, so the app with the better star average is not the one people write more warmly about.
Radiant ships an update every 3 months, Only One weekly. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
