Verdict
The clearest difference is price: MaintainX at Free against DeltaAuto's $0.99. MaintainX also leads on ratings volume (5.9K vs 1). DeltaAuto's advantage is update cadence (daily vs weekly) and iOS requirement (12.0 vs 16.4). On rating, ads, in-app purchases and device support there is nothing between them.
