Verdict

The call

The clearest difference is in-app purchases: Pythagorean theorem App at none against Trigonometry calc's 1. Pythagorean theorem App also leads on ads (none vs shown). Trigonometry calc's advantage is update cadence (every 3 months vs every 9 months). On price, device support and iOS requirement there is nothing between them.
