# Portal Door vs Falling Filter

The clearest difference is rating: Falling Filter at 4.6 against Portal Door's 3.0. Falling Filter also leads on ratings volume (2.3K vs 2) and update cadence (every 5 days vs fortnightly). Portal Door's advantage is in-app purchases (none vs 3) and review sentiment (50% vs 16%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Falling Filter sells 3 in-app purchases, starting at $4.99 per 7 days. Portal Door asks for nothing beyond the download.

Falling Filter holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Falling Filter has 2.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Portal Door's written reviews are positive against 16% of Falling Filter's, so the app with the better star average is not the one people write more warmly about.

Portal Door ships an update fortnightly, Falling Filter every 5 days. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
