# Astro vs ACC Learn

The clearest difference is rating: ACC Learn at 4.6 against Astro's 4.0. ACC Learn also leads on ratings volume (969 vs 3) and review sentiment (60% vs 50%). Astro's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (9.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

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

ACC Learn holds the better App Store score, 4.6 against 4.0.

Written reviews point the same way: 50% of Astro's written reviews are positive against 60% of ACC Learn's.
