What is RAPT? RAPT is Really Awesome Product Technology. RAPT is a brand new method for total fermentation control. RAPT is internet enabled. RAPT uses the Internet of Things (IoT) to enable real time logging, real time access and real time control. This technology allows for seamless integration of all of your RAPT enabled products, controllable and accessible from any of your devices. The RAPT App allows simple, seamless, integrated control over every one of your RAPT enabled devices, no matter where you are or what you are doing. RAPT is perfect for any and all your fermentation needs – beer making, wine, salami, kimchi – almost anything where temperature and/or pressure control is an important part of the process. We asked ourselves what people really wanted from a fermentation chamber. What would you design if you were starting from scratch? A ground up rework, if you will. And RAPT was the result. The RAPT Fermentation Chamber and the RAPT Pill are the first steps towards seamless integration, and the RAPT App is the easiest way to control everything.

Verdict
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.
