# Express Converter vs Scrolla

The clearest difference is rating: Express Converter at 5.0 against Scrolla's 4.3. Express Converter also leads on in-app purchases (none vs 3) and review sentiment (100% vs 87%). Scrolla's advantage is update cadence (every 3 days vs every 9 days) and ratings volume (15 vs 3). On price, ads, device support and iOS requirement there is nothing between them.
