# WOW Filterbox vs Stravinski

The clearest difference is rating: WOW Filterbox at 4.6 against Stravinski's 4.0. Stravinski's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs every 4 months). On price, ratings volume and ads there is nothing between them.

Both are free to download. WOW Filterbox sells 1 one-off in-app purchase. Stravinski asks for nothing beyond the download.

WOW Filterbox holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 30 and 21 respectively. Written reviews complicate that: 64% of WOW Filterbox's written reviews are positive against 86% of Stravinski's, so the app with the better star average is not the one people write more warmly about.

WOW Filterbox ships an update every 4 months, Stravinski every 5 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
