Verdict

The call

The clearest difference is in-app purchases: Problem solver at none against Physics's 4. Problem solver also leads on device support (3 vs 1) and iOS requirement (8.0 vs 17.0). Physics's advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On price there is nothing between them.
