Plynx - Arduino ESP32 Control
IoT dashboards for your boards
Free · Designed for iPhone. Not verified for macOS.
Control your Arduino, ESP32 or ESP8266 from your iPhone. Add your board, flash the sketch the app writes for you (no token to copy by hand), and tap Connect: your first button is live in minutes, on a canvas that belongs to that board alone.
HOW IT WORKS
1. Add your board in the app and pick its type
2. Copy the ready-made sketch onto the board
3. Tap Connect. A button wired to your board is already on the canvas
When you outgrow one board, classic projects let you mix widgets from every board on your account in a single dashboard.
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
- Siri and Shortcuts: ask Siri to flip a pin, or drop Plynx into any automation
- 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: 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. Not into self-hosting? A free public instance is available too.
FREE, WITH NOTHING TO UNLOCK
No ads, no subscriptions, no features locked behind a paywall. The protocol library is open source on GitHub.
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.
Ratings & Reviews
A brand new welcome: tell Plynx what you want to build and your first project, dashboard and guided tour are ready when you sign in.
Control your board from Discord with /plynx, and get Telegram or Discord alerts from a widget, even when the app is closed.
Archimedes now draws the wiring diagram for your board and lists the parts you need, and shows each step while it works.
Firmware over Bluetooth: download an update where you have signal, install it on the board later.
A cleaner sign-in screen, and fixes for the LCD widget, edit gestures and Bluetooth settings.
