Verdict

The call

The clearest difference is rating: SimplyRead at 5.0 against Compress's 4.4. SimplyRead also leads on update cadence (weekly vs every 2 weeks) and iOS requirement (16.0 vs 18.0). Compress's advantage is in-app purchases (none vs 1) and ratings volume (7 vs 1). On price, ads and device support there is nothing between them.
