Verdict
The clearest difference is price: TriCalc at Free against Triangle Calc A's $0.99. TriCalc also leads on update cadence (fortnightly vs every 56 months) and iOS requirement (13.0 vs 26.0). Triangle Calc A's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
