Verdict
The clearest difference is price: Physics Quest at Free against Abacus Practice's $0.99. Physics Quest also leads on in-app purchases (none vs 1) and update cadence (every 2 days vs every 4 months). Abacus Practice's advantage is ads (none vs shown). On device support there is nothing between them.
