# OTP Auth vs TOTP

The clearest difference is rating: OTP Auth at 3.4 against TOTP's 1.0. OTP Auth also leads on ratings volume (19 vs 1). TOTP's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. OTP Auth sells 1 one-off in-app purchase. TOTP asks for nothing beyond the download.
