Verdict

The call

The clearest difference is in-app purchases: Atriumy at none against HPLC Calculator's 6. Atriumy also leads on ads (none vs shown) and update cadence (every 4 days vs every 5 weeks). HPLC Calculator's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
