# Horizon Aqua vs Flash Studio

The clearest difference is rating: Flash Studio at 4.8 against Horizon Aqua's 3.3. Flash Studio also leads on review sentiment (58% vs 28%) and ratings volume (5.8K vs 3). Horizon Aqua's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, 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.

Flash Studio holds the better App Store score, 4.8 against 3.3.
