Verdict
The clearest difference is ratings volume: Window at 11K against BurnFast's 4. Window also leads on rating (4.5 vs 4.3) and device support (4 vs 2). BurnFast's advantage is update cadence (every 9 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Window sells 9 in-app purchases, starting at $4.99 per 7 days and BurnFast sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Window holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Window has 11K ratings behind it against 4, so its average is the more settled of the two.
Window ships an update monthly, BurnFast every 9 days. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
