# Authenticator ® App vs Smart Day Calendar

The clearest difference is rating: Smart Day Calendar at 5.0 against Authenticator ® App's 4.4. Smart Day Calendar also leads on ads (none vs shown) and update cadence (every 9 days vs every 5 weeks). Authenticator ® App's advantage is ratings volume (3.4K vs 1) and chart position (#80 vs unranked). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Authenticator ® App sells 12 in-app purchases, starting at $7.99 per 7 days and Smart Day Calendar sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Smart Day Calendar holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Authenticator ® App has 3.4K ratings behind it against 1, so its average is the more settled of the two.

Authenticator ® App ships an update every 5 weeks, Smart Day Calendar every 9 days. The most recent releases landed on October 25, 2026 and October 9, 2026 respectively.
