# Flipd vs No Zero Days

The clearest difference is in-app purchases: No Zero Days at none against Flipd's 18. No Zero Days also leads on review sentiment (80% vs 49%) and iOS requirement (8.0 vs 13.0). Flipd's advantage is ratings volume (7K vs 47) and rating (4.5 vs 4.3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Flipd sells 18 in-app purchases, starting at $1.99 per 7 days. No Zero Days asks for nothing beyond the download.

Flipd holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Flipd has 7K ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 49% of Flipd's written reviews are positive against 80% of No Zero Days's, so the app with the better star average is not the one people write more warmly about.

Flipd ships an update every 11 days, No Zero Days fortnightly. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
