Verdict
The clearest difference is rating: GPCommit at 5.0 against IMSA's 4.1. GPCommit also leads on ads (none vs shown) and monetization model (free vs ad-supported). IMSA's advantage is ratings volume (69 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.

GPCommit holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: IMSA has 69 ratings behind it against 1, so its average is the more settled of the two.
IMSA ships an update every 2 months, GPCommit every 6 weeks. The most recent releases landed on October 4, 2026 and September 20, 2026 respectively.
