Verdict
The clearest difference is in-app purchases: AonenCharge at none against MEL Expiry Calc's 1. AonenCharge also leads on ads (none vs shown). MEL Expiry Calc's advantage is update cadence (every 2 months vs every 4 months) and iOS requirement (13.0 vs 15.2). On price and device support there is nothing between them.
