# Engbird vs QZsmart

The clearest difference is rating: QZsmart at 4.3 against Engbird's 1.8. QZsmart also leads on ratings volume (113 vs 37). Engbird's advantage is update cadence (every 6 weeks vs every 10 months) and review sentiment (13% vs 5%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

QZsmart holds the better App Store score, 4.3 against 1.8. Both are backed by a comparable volume of ratings — 37 and 113 respectively. Written reviews complicate that: 13% of Engbird's written reviews are positive against 5% of QZsmart's, so the app with the better star average is not the one people write more warmly about.
