Verdict
The clearest difference is price: Tinkercad at Free against Grade Aid's $2.99. Tinkercad also leads on ratings volume (19K vs 2) and iOS requirement (15.6 vs 26.0). Grade Aid's advantage is update cadence (monthly vs every 13 months) and rating (5.0 vs 4.6). On ads and in-app purchases there is nothing between them.
