Verdict
The clearest difference is in-app purchases: Vacuum Link at none against HPLC Calculator's 6. Vacuum Link also leads on ads (none vs shown) and iOS requirement (8.0 vs 13.0). HPLC Calculator's advantage is update cadence (every 5 weeks vs every 18 months). On price and device support there is nothing between them.
