Verdict
The clearest difference is review sentiment: Reink at 50% against Keefrash's 0%. Reink also leads on ads (none vs shown) and monetization model (free vs ad-supported). Keefrash's advantage is rating (4.2 vs 3.0) and update cadence (every 8 days vs every 2 weeks). On price, 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.
Keefrash holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Reink has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 50% of Reink's written reviews are positive against 0% of Keefrash's, so the app with the better star average is not the one people write more warmly about.
Reink ships an update every 2 weeks, Keefrash every 8 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
