Verdict

The call

The clearest difference is in-app purchases: Mini Keyboard at none against Electronic Circuit Calculator's 1. Mini Keyboard also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). Electronic Circuit Calculator's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
