Verdict
The clearest difference is in-app purchases: CalcDraw at none against SumsApp's 3. CalcDraw also leads on rating (4.8 vs 4.6). SumsApp's advantage is ratings volume (169 vs 4) and update cadence (every 9 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
