Plynx - Arduino ESP32 Control
IoT dashboards for your boards
Free · Designed for iPhone. Not verified for macOS.
Turn your iPhone into a remote for Arduino, ESP32, ESP8266 and Raspberry Pi. Add a board, drop in widgets, control it live. Faster setup, plus direct Bluetooth (beta).
Control your Arduino, ESP32 or ESP8266 from your iPhone. Build the dashboard for your project in minutes: drag widgets onto a canvas, bind each one to a pin, and watch sensor values stream in live while buttons and sliders drive your outputs.
HOW IT WORKS
1. Create a project in the app and add your widgets
2. Flash a small library on your board with the token the app gives you
3. Done. Your hardware and your phone are talking
Great for irrigation systems, aquarium and terrarium controllers, garage doors, weather stations, water tanks, battery monitors, or whatever you are soldering this weekend.
WIDGETS
Buttons, sliders, gauges, charts, joystick, RGB picker, LCD, terminal, level indicators, value displays, tabs, timers and more. Over 30 widgets, each one configurable with themes that look good in light and dark.
AUTOMATIONS
Rules run when a sensor crosses a threshold, at a set time, at sunrise or sunset, or when you arrive at or leave a place. Set them once, keep the phone in your pocket.
BEYOND THE APP
- Home Screen widgets: toggle a pin without even opening the app
- Lock Screen widgets for your most important values
- Apple Watch app: read sensors, move sliders and run Scenes from your wrist
- Live Activities: a running Timer stays on your Lock Screen and in the Dynamic Island
- Offline mode: dashboards keep showing the last known values
BLUETOOTH, NO WIFI (BETA)
Connect an ESP32 over Bluetooth and control it directly from your iPhone. No WiFi, no server, no account: flash the sketch, pick the board from the list, done.
YOUR DATA, YOUR SERVER
Plynx talks directly to a small open source server you can host yourself on any Raspberry Pi. No cloud account with us, no telemetry, nothing in the middle. Not into self-hosting? A free public instance is available too.
FREE, WITH NOTHING TO UNLOCK
No ads, no subscriptions, no device limits.
Compatibility note: Plynx speaks the classic Blynk Legacy protocol, so existing legacy servers and dashboards work out of the box. Plynx is an independent app, not affiliated with, endorsed by, or sponsored by Blynk Inc. The Blynk name is used only to describe protocol compatibility.
Requires iOS 18+. Works with Arduino, ESP8266, ESP32 and Raspberry Pi.
