What Python IDE & Jupyter does

Python IDE & Jupyter – Juno is a mobile app published by Rational Matter Ltd. Apple categorizes it under Developer Tools, and this guide treats it as a focused code editor offline tool. It combines the official listing, current version metadata, supported-language record, screenshots and verified store links so readers can understand the product before installing it.

The developer's App Store description explains: “Zero-setup Python IDE that runs your code offline, an AI coding assistant, and a developer toolbox — in a first-class citizen app for iPad and iPhone.” This is attributed product information rather than an independent hands-on claim. Use the official screenshots below to compare the described workflow with the current interface in the store.

How to install Python IDE & Jupyter on iOS

Open the Apple App Store button on this page, confirm that the title and publisher match Python IDE & Jupyter – Juno by Rational Matter Ltd, review the age, privacy and in-app-purchase information shown for your region, and then use Get or the displayed price button. The captured minimum iOS requirement is 17.0.

Only an Apple App Store entry could be confirmed from first-party sources for this record. An Android label is intentionally not shown. This does not prove that an Android edition is impossible; it means no matching Google Play entry was verified well enough to publish without guessing a package name.

Use the official store button rather than a third-party APK or download mirror.

Getting started with Python IDE & Jupyter

Juno is designed to cover all your Python coding needs, supporting both Python scripts (.py) and Jupyter notebooks (.ipynb) — a document format focused on applying Python to data analysis and computational science. Start with the narrow task described in the listing and use a non-sensitive example for the first run. Follow the onboarding or first-screen instructions actually shown by the current version rather than granting every optional permission in advance.

Navigate and manage files and folders, quickly preview documents and media - Browse and edit Jupyter notebooks in a powerful, customizable notebook editor with beautifully rendered previews — editing is free - Write and edit code sources, scripts, JSON, XML, and other text-based formats — one versatile editor for code and text alike, with syntax highlighting - Add quick access bookmarks for file system locations outside the app's sandbox, or simply open documents in place If the app offers import, sync, notifications, cloud processing, location, contacts, microphone, photo-library or file access, enable only the permission needed for the function you are testing. Settings and control names can move between releases, so the live app and developer support page remain the final reference.

Documented features and example workflow

Only one thing in Juno is Pro: running code. Even that is free to try — a generous trial allowance lets you run notebooks, scripts, projects, and the REPL before you buy. After the trial, running code unlocks with a one-time Pro purchase — not a subscription. The official screenshots captured for this page show the product interface and documented functions as they appeared in the App Store. They are useful for finding the main controls, but a later release, device size or account state may look different.

A practical evaluation is to complete one code editor offline task from start to finish, note which information the app asks for, and check whether the result can be edited, exported, shared or backed up when the listing says those functions are available. Keep the original item until the output has been verified, especially for scans, recordings, finance records, health reminders, routes or converted files.

Who Python IDE & Jupyter is for

Python IDE & Jupyter is most relevant to people who repeatedly need a code editor offline workflow and prefer a purpose-built mobile utility over a broad suite. The Developer Tools classification and the developer's description are useful starting points, but suitability depends on the exact device, region, account requirements and data involved.

Evaluate it with a real but low-risk example. Compare the steps, output quality and ongoing permissions with the method you already use. Keep the app only when the focused benefit is clear; for medical, financial, navigation or security-related tasks, independently verify important reminders, totals, locations and recommendations.

Price, paid features and account requirements

Apple listed the initial download as Free, while the official description mentions premium, subscription, trial or in-app-purchase language. The captured metadata does not provide a permanent table of every plan. Check the current in-app purchase screen for regional prices, renewal periods, limits and cancellation instructions.

Account requirements may differ by function. A local utility can work immediately, while synchronization, cloud backup, AI processing, shared lists, premium templates or support may require sign-in or a paid plan. The store page and in-app checkout shown at the time of purchase take precedence over this dated directory record.

Recorded App Store price: Free.
Check whether the exact feature you need is included before starting a trial.
Review renewal and cancellation terms in the current store account settings.

Compatibility, languages, privacy and current version

The captured App Store metadata records version 4.2.4, updated 2026-09-03, with a minimum iOS version of 17.0 and a download size of 661.4 MB in the captured listing. It reports 8 language codes (EN, FR, DE, JA, RU, ZH, ES, ZH). These values can change, so confirm the latest compatibility and release notes on the official store before installing on an older device.

The language list, version and screenshots are factual store metadata, but they do not establish how the developer handles personal data. Review the current App Privacy section and the developer's privacy policy before entering confidential content. Limit photo, location, microphone, contact, notification and local-network permissions to functions you actually use.

Recorded version: 4.2.4.
Recorded update date: 2026-09-03.
Recorded supported-language codes: EN, FR, DE, JA, RU, ZH, ES, ZH.

Common questions and troubleshooting for Python IDE & Jupyter

People searching for “python ide jupyter” and “python ide jupyter notebook” commonly need the official download, a feature explanation, compatibility details or help starting the app. This page links to the verified store entry and does not host an IPA or APK. If installation fails, check the device OS version, available storage, store region and account restrictions before retrying.

If Python IDE & Jupyter opens but a function is missing, compare version 4.2.4 with the current store release, review the permission required by that function, and check the developer's support material. For sync or account issues, confirm network access and account status. Preserve original data before reinstalling, and remove the app if its present permissions, pricing or behavior no longer match your needs.
