First of all thanks for implementing this I have been using it with my pico and ble module. I wanted to support it so I purchased everything. However there are some bugs in the app. First: When you go back to the main menu it is still connected to the device however there is no chance to reach it. always requires restarting the app. It would be also nice to connect directly to your project instead establish the connection everytime. It would be nice to remember the device. 2) Gamepad doesnt work for me. 3) Lack of customization of the buttons are painful. It would be nice to scale buttons drag them as you want and create like a turntable menu with pre-defined button sets. For example I would like to use a joystick and 10 different keys but there is no way to use such a thing. Needs more freedom. 4) Overall UI is much better than any other app in the app store congrats. ### 2/5 — Disconnects a lot *2022-06-07* Are used to test function in the free version many times before making the decision to purchase the unlock everything option. I noticed that after purchase, my Arduino will not stay connected via Bluetooth to the app anymore, the app locks up frequently, and I had none of those problems when I was using it in the free mode. The options with everything unlocked are somewhat limited, you can’t see what the controller looks like or what the options are for it before buying. While it kind of works for what I want, I wouldn’t recommend this product ### 1/5 — Doesn’t work *2022-05-27* Won’t stay connected to Arduino. ### 1/5 — Unreliable *2022-05-06* Keeps disconnecting from the Bluetooth transmitter, making the connection unreliable. I’ve had more reliability with other apps and the same device. ### 1/5 — Very limited functionality. *2022-04-14, version 1.7* When I can get this to work it seems to have a very limited choice of UI controls. Unless I’m doing something wrong, it seems that the “fully customisable“ option which I paid for only gives me the option of a button or a toggle. I want more capability and hope I can find it with another app. I don’t know how I am supposed to save a screen of UI controls for future use and I have to restart the app each time otherwise I just get a blank white screen. Perhaps I just haven’t understood how it works but there seems to be explanation. ### 4/5 — Si *2022-03-10, version 1.7* Bueno ### 1/5 — No me sirvió *2021-11-25, version 1.7* No me funciono y no me daba ninguna opción ### 5/5 — Great app. Though it could be perfected. *2021-04-21, version 1.4* I am using this on a very simple arduino app. In terminal I send any character to the arduino and it sends back sensor data. The app does this well and I’m delighted. There are a few things I would change. 1. When the app launches on the ‘choose a Bluetooth device’ page the app shuts down my music. Not sure why. I don’t like that. 2. I always connect to the same device. But that device will be in a seemingly random spot in a long list. 3. I wish the app would simply reconnect with the last used device. I often have to force quit to get the device to pair again. 4. My arduino sends four lines of data, maybe 20 characters a line. The app adds line breaks. It seems that after a certain amount of text it just resets something and jumps to a new line. I believe this can be fixed with a different way of receiving the terminal data from the arduino. Again. Great app. Highly recommend it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Absolute Garbage *2026-05-26* As a microcontroller developer who releases a lot of MIT-licensed code, I was looking for a nice Bluetooth app for my iPhone that I could use to my interact with my favorite microcontroller. I don’t use the Arduino, but that doesn’t matter; it’s all about serial communications. Let me just keep this short. This app will waste your time and your money. It barely works, and has a horrible interface that is not intuitive. It looks very sexy in the App Store, but after you’ve spent your 12 bucks to unlock everything, it’s nothing but a nightmare. ### 1/5 — Unusable *2025-12-02* App will not stay connected long enough to build a button. Do not buy! ### 1/5 — Tệ *2025-06-07, version 2.0* Tệ ### 1/5 — No agarró conexión. *2024-11-07, version 1.9* No conecto mi robot, no agarra las conexiones ### 1/5 — Awful app *2024-08-24* Worst purchase of my life I decided to purchase the "custom" mode to make a control panel for my BLuno. It only allows you to add buttons and switches, no sharing sensor data and no custom controls. Besides the very limited customization, the Bluetooth capability– the ENTIRE POINT of the app– barely works as intended. It's a pain to connect your board. Sometimes it registers as simultaneously connected and not connected so you need to restart the app. Don't waste your time on this and get a free standard Bluetooth scanning app. Any scanner will have better control and more information than this piece of junk app. ### 1/5 — Falcon K rocket *2023-11-23* Just did a latency test.. 68 mS! Plaz some one tell me the best electrics to buy Text me the list @ 386-480-8483. Money is a problem. Thans ### 1/5 — Basically useless on iPhone *2023-11-07* “Fully Custom” sounds amazing, in reality it is only buttons, which once created are completely un editable, you can’t even delete them. No instructions, and pretty damn expensive for essentially nothing. Don’t make the mistake I did and purchase the unlocks! **Developer response:** Long press for editing/delete ### 1/5 — This is troubling *2023-05-30, version 1.9* Nothing but a locked screen ### 1/5 — Some good but more bad *2023-04-17, version 1.9* This was a really simple and great app at first it worked, The controller would definitely have been worth the 5$ if it worked reliably, then it didn’t it only works if Arduino is connected to computer. This app cause me a lot of headache thinking something was wrong with my Arduino circuit, testing every wire and making sure it’s at right voltage to only find out hours later that it was the app acting up. It’s already bad enough that iOS is really dodgy with Arduino, just download a hm10 reader on App Store and manually write the commands, so much better. ### 1/5 — Useless *2022-09-01, version 1.7* Simply doesn’t work. No sign of life! Blank page. ## Most praised reviews (10 highest-rated) ### 5/5 — Ok *2026-05-18, version 2.1* Very good ### 5/5 — Great App *2023-11-30* I can’t get it to attach to my 05Bluetooth adapter for Arduino. ### 5/5 — Space K rocket *2023-11-23* We have been building and designing several different styles of drones from ultra long range called “ big hex” hexocopter to private protection drones that fly a pre programmed course around ur house if one of many sensors triggers then lands back on its pad and begins charging. All by it self We have developed 7 types of FPV race freestyle and ultra long range. 80 miles! Our next project we’re building is a 6” 2 stage rocket 1 is engine B12-4 2 is C15 10 The unique part of this is we want to be able to read telemetry and gather blackbox. Here is the challenge. We are using arduiono parts only. That means we Need a small powerful Arduino that has at a clock speed to have prefials to run a 6 axi gyro “ serial of course. GPS with barometer, a pwm anolog servo controls. The main board will also need a crossfire RX or ELRS in order to get real time updates and if need take manual adjustments or “ for safety incinerate of something goings wrong. I am asking the community if they have herd, know, or have done this before and what list of Arduino parts I must obtain we have the rocket built using think cardboard, carbon fiber and lots of 3d printing. Now it’s just time for the electronics. If anyone knows what’s the best. Plz send me a list and ur name and lunch is set for January 4th live on YouTube and ticktock and would be happy to give you credit for ur contribution Thank Owner StiXs UAV Tech LLc Eli H. ### 5/5 — Very cool *2023-11-11* Loving this ### 5/5 — Arduino Bluetooth *2022-09-28, version 1.7* Esta de lujo ### 5/5 — Great app, worked perfectly for my needs *2022-05-19, version 1.7* I couldn’t ask for more from a free app ### 5/5 — Love this app! *2022-04-09* I make my own dot matrix displays which utilize the Atmega 328p-pu microcontroller (the same one the arduino uno uses) and this app makes a breeze to add and change stored messages at the push of a button. I love it! I highly recommend this app! ### 5/5 — Merci *2022-02-16* 5 ### 5/5 — Bastante buena *2021-09-02, version 1.6* Genera una conexión sencilla manteniendo una buena comunicación entre el teléfono y el monitor. ### 5/5 — dpaaaain *2021-07-29* awesause --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
