# RAPT vs Flash Studio

The clearest difference is rating: Flash Studio at 4.8 against RAPT's 1.6. Flash Studio also leads on review sentiment (56% vs 15%) and update cadence (weekly vs every 4 months). RAPT's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, 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 1.6. That said, the two scores are not equally well evidenced: Flash Studio has 3.4K ratings behind it against 20, so its average is the more settled of the two. Written reviews point the same way: 15% of RAPT's written reviews are positive against 56% of Flash Studio's.

RAPT ships an update every 4 months, Flash Studio weekly. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
