# my Installed Base vs StackLock

The clearest difference is in-app purchases: my Installed Base at none against StackLock's 1. my Installed Base also leads on rating (5.0 vs 4.5). StackLock's advantage is update cadence (every 2 days vs every 4 months) and ratings volume (74 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. StackLock sells 1 in-app purchase, starting at $14.99 per month. my Installed Base asks for nothing beyond the download.

my Installed Base holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: StackLock has 74 ratings behind it against 1, so its average is the more settled of the two.
