The clearest difference is review sentiment: Calculator Lock at 76% against App lock's 13%. Calculator Lock also leads on rating (4.6 vs 4.0) and ratings volume (6.1K vs 757). App lock's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. App lock sells 3 in-app purchases, starting at $3.99 per month and Calculator Lock sells 7 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
