# Safe vs Frequency

The clearest difference is ads: Safe at none against Frequency's shown. Safe also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.7). Frequency's advantage is update cadence (fortnightly vs every 56 months) and ratings volume (1.1K vs 9). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Safe holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Frequency has 1.1K ratings behind it against 9, so its average is the more settled of the two.

Safe ships an update every 56 months, Frequency fortnightly. The most recent releases landed on October 6, 2026 and October 27, 2026 respectively.
