# SpoolMate vs Protokit

The clearest difference is ads: Protokit at none against SpoolMate's shown. Protokit also leads on update cadence (every 6 days vs every 2 weeks) and iOS requirement (15.1 vs 17.6). SpoolMate's advantage is ratings volume (3 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for SpoolMate against 5.0 for Protokit. Both are backed by a comparable volume of ratings — 3 and 1 respectively.

SpoolMate ships an update every 2 weeks, Protokit every 6 days. The most recent releases landed on June 27, 2026 and September 19, 2026 respectively.
