Verdict
The clearest difference is in-app purchases: ClearSpace at none against ChangeWatcher's 3. ClearSpace also leads on ads (none vs shown). ChangeWatcher's advantage is update cadence (every 8 days vs every 3 weeks) and iOS requirement (18.0 vs 26.6). On price and device support there is nothing between them.
