# invsi vs 应用锁+

The clearest difference is rating: 应用锁+ at 5.0 against invsi's 4.1. invsi's advantage is ratings volume (8 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. invsi sells 4 in-app purchases, starting at $0.99 per month and 应用锁+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

应用锁+ holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: invsi has 8 ratings behind it against 1, so its average is the more settled of the two.

invsi ships an update fortnightly, 应用锁+ every 8 days. The most recent releases landed on October 8, 2026 and October 7, 2026 respectively.
