Using hm-10 module with esp-12e. Real time results. Wonderful sliders, button design, and the tilt and joystick are awesome features. Plus the follow line has potential to give pwm output. Otherwise, works great and love the features. Awesome developer. Recommend for the supported Bluetooth modules. My first review on App Store over 5 years. 10/10

Works well, very easy to use. Wish-List though. 1: Would be nice if texts sent to phone would show when app is not actively visible. I.E. alarm alerts are not very useful if I have to be looking at the app itself to see them. (If even possible) 2: would be nice if I could rename buttons and sliders without having to recreate the entire list. 3: would be really cool if I could create a button that was a pull down/scroll list of variables to select from/send. I.E. select from a list colors for led strip. 4: auto reconnect BLE when back in range. (If even possible) If the above were true, it would be a great companion to many of my hardware products.

I am using iPhone 7, newest version of Arduino, running Linux on a Chromebook.This app is outstanding and works as advertised. Highly documented which is easily understood, with many example programs which compile without errors.I highly recommend this app if you need a Bluetooth remote. GREAT JOB!

Tried a handful apps and end up concluding this one is so far the best control app on iOS for Arduino DIYers. The documentation and examples are great and informative for beginners.
