TOTP Calc
Read full descriptionHide full description
TOPT Calc calculates a TOTP (Time-based One-Time Password) code based on a known secret key. The application is more secure than standard ones because: - it does not know anything about the user's account - it does not store anything internally - the secret key can be stored separately (e.g. on paper)

Verdict
The clearest difference is price: AppLocker at Free against TOTP Calc's $0.29. AppLocker also leads on update cadence (every 3 days vs every 5 weeks) and iOS requirement (16.0 vs 18.0). TOTP Calc's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
