Verdict
The clearest difference is rating: Offcha at 4.8 against Lowkey's 4.0. Lowkey's advantage is ads (none vs shown) and review sentiment (71% vs 41%). On price, update cadence, in-app purchases 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
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Offcha holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Lowkey has 84 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 41% of Offcha's written reviews are positive against 71% of Lowkey's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 6 weeks. Both last shipped on November 3, 2026.
