Verdict

The call

The clearest difference is rating: TTsolar at 5.0 against Electronic Circuit Calculator's 4.0. TTsolar also leads on in-app purchases (none vs 1) and ads (none vs shown). Electronic Circuit Calculator's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (5 vs 1). On price, monetization model and device support there is nothing between them.
