# TennisLocker vs ServiceLine

The clearest difference is rating: ServiceLine at 5.0 against TennisLocker's 4.4. TennisLocker's advantage is ratings volume (65 vs 6) and iOS requirement (16.6 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ServiceLine holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: TennisLocker has 65 ratings behind it against 6, so its average is the more settled of the two.
