Verdict

The call

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.
