# MathNotes vs 2FA Authenticator

The clearest difference is rating: 2FA Authenticator at 5.0 against MathNotes's 4.5. MathNotes's advantage is update cadence (every 4 days vs every 10 days) and ratings volume (8 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MathNotes sells 8 in-app purchases, starting at $1.99 per month and 2FA Authenticator sells 4 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

2FA Authenticator holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MathNotes has 8 ratings behind it against 1, so its average is the more settled of the two.

MathNotes ships an update every 4 days, 2FA Authenticator every 10 days. The most recent releases landed on October 8, 2026 and September 30, 2026 respectively.
