Verdict

The call

The clearest difference is rating: ComicBase Mobile at 5.0 against Proton Calendar's 4.1. ComicBase Mobile also leads on in-app purchases (none vs 2) and update cadence (every 2 weeks vs every 5 weeks). Proton Calendar's advantage is ratings volume (1.6K vs 2) and review sentiment (41% vs 25%). On price, ads, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ComicBase Mobile holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Proton Calendar has 1.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 25% of ComicBase Mobile's written reviews are positive against 41% of Proton Calendar's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ComicBase Mobile ships an update every 2 weeks, Proton Calendar every 5 weeks. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
