# Locksub vs Invoice Maker

The clearest difference is rating: Invoice Maker at 4.8 against Locksub's 4.0. Invoice Maker also leads on ratings volume (109K vs 2) and chart position (#8 vs unranked). Locksub's advantage is in-app purchases (none vs 24) and iOS requirement (12.0 vs 15.6). On price, update cadence, ads and device support there is nothing between them.
