Verdict
The clearest difference is in-app purchases: Shape Defense at none against ONOMATOPIA's 10. Shape Defense also leads on ads (none vs shown) and update cadence (every 2 days vs every 11 days). ONOMATOPIA's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.2). On price there is nothing between them.
