IoMob

Live Elixir notebooks on your iPhone. Write code, fetch live data, and build interactive charts, all on-device. No setup, no server, no cloud.

Io brings live Elixir notebooks to your phone. Write code, run it instantly, and see the results render right below it, all on the device in your pocket. No laptop, no server to spin up, no cloud account.

Built on Livebook, Io turns the interactive notebook experience into a native mobile app. Open a notebook, evaluate a cell, and watch charts, tables, and outputs appear inline as you work.

What you can do:

• Write and run real Elixir, the language that powers Phoenix and the BEAM.
• Use Mix.install to pull in many Hex libraries on demand.
• Fetch live data over the network and transform it with the full power of the language and OTP.
• Build interactive inputs, forms, and controls with Kino.
• Render data tables and rich, interactive charts with VegaLite.
• Organize your work into sections and notebooks you can revisit and re-run.
• Open .livemd files shared from other apps and pick up right where they left off.

Everything runs on-device. Your code and your data stay on your phone unless you choose to send them somewhere, which makes Io a great companion for learning, prototyping, quick calculations, data exploration, and tinkering with Elixir wherever you happen to be.

Whether you are an Elixir developer who wants a notebook in your pocket, a student learning the language, or someone who just likes to compute on the go, Io gives you a real, full-featured environment with nothing to configure.
