Verdict

The call

The clearest difference is in-app purchases: Physical Constants at none against Biological Code's 6. Biological Code's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 9 months). On price, device support and iOS requirement there is nothing between them.
