Verdict
The clearest difference is review sentiment: Week at 100% against BattAir's 25%. Week also leads on update cadence (every 2 weeks vs monthly). BattAir's advantage is price (Free vs $0.99) and iOS requirement (11.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
