Verdict
The clearest difference is rating: ShiftLock at 3.2 against Auto Bounds's 2.5. ShiftLock also leads on update cadence (every 5 months vs every 20 months) and chart position (#44 vs unranked). Auto Bounds's advantage is ads (none vs shown) and review sentiment (67% vs 35%). On in-app purchases, device support and iOS requirement there is nothing between them.

Auto Bounds costs $4.99 and ShiftLock $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ShiftLock holds the better App Store score, 3.2 against 2.5. That said, the two scores are not equally well evidenced: ShiftLock has 41 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 67% of Auto Bounds's written reviews are positive against 35% of ShiftLock's, so the app with the better star average is not the one people write more warmly about.
Auto Bounds ships an update every 20 months, ShiftLock every 5 months. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
