Verdict
The clearest difference is in-app purchases: ArcSphere at none against MuseWrite's 2. ArcSphere also leads on ratings volume (105 vs 1). MuseWrite's advantage is update cadence (every 3 days vs every 10 days) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.

ArcSphere ships an update every 10 days, MuseWrite every 3 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
