Arduino & ESP32 IDE for Android
Write your code on your phone, compile it on the device, and flash your board directly over a USB OTG cable. No computer is required — the compiler runs on your device.

Genuine screenshots taken directly from the app.
Features
The desktop IDE, running on your phone.
Code is compiled on the device and is not sent to a cloud server. It works without an internet connection.
Connect your board with an OTG cable and write the compiled output directly to it. AVR and ESP32 are supported.
Syntax highlighting, a word completion bar, multi-file projects and full-screen editing.
Monitor board output in real time, send data and change baud rates.
Example projects from Blink to WiFi and sensors; library examples are included in the list as well.
Upload speed, flash mode, partition scheme and core debug level remain under your control.
Pricing
The free version provides 10 uploads per week and displays advertisements. The Pro version has no limits and no advertisements.
Ad-free use, unlimited uploads and a monthly AI allowance. Monthly or yearly.
Everything included in Pro, together with a considerably larger AI allowance. As every AI request incurs a processing cost, Pro Max is offered for a fixed term — monthly or yearly — and does not renew automatically.
If your monthly AI allowance is used up during the month, you may purchase a one-time pack. A pack provides AI allowance only; ad-free use and unlimited uploads are included in a subscription, not in a pack. If you do not hold a subscription, or you are on Pro, we recommend reviewing the plans above first: they provide more for less.
The code is delivered by e-mail and is entered in the app under More > Sketch32 Pro. The balance is valid for 30 days from the day it is redeemed. If you purchase more than one pack, the codes may be entered individually and the allowances are combined.
Your license key is sent to your e-mail address after payment. Simply enter it under More > Sketch32 Pro in the app. Each key is valid on a single device.
No plan renews automatically. No further charge is applied when the term ends; the app simply continues as the free version.

We will send the plans, pricing and payment link to your e-mail address.
FAQ
Yes. The toolchain runs inside the app; your code is never uploaded to a server, and you can compile and flash without an internet connection.
Arduino-compatible AVR boards (Uno, Nano and similar) and the ESP32 family. The current list is available in the Boards tab within the app.
10 per week, resetting every Monday. You may also earn additional uploads by watching rewarded advertisements. The Pro version has no limit.
On a single device. The key is bound to the first phone on which it is activated. If you change devices, please contact us from the Support screen in the app and we will release the device binding.
When the term ends, Pro features are disabled and the app continues to operate as the free version. As plans do not renew automatically, no further charge is applied to your card; you may obtain a new key at any time to continue.
You may purchase a one-time additional pack. A pack is not a subscription: it does not renew, it does not change your plan, and it is added on top of your existing allowance. The code is delivered by e-mail and is entered in the app under More > Sketch32 Pro. The balance is valid for 30 days from the day it is redeemed.
Some charging cables carry power only and contain no data lines. If the board is not detected, please first try an OTG cable that supports data transfer.
