What's New in NearbiJSX

1.4.6

November 5, 2026

- Choose React 18 or React 19 manually for JSX and TSX documents. - New Pro SQLite tools give each document its own database: create tables, edit records, run SQL, and import or export compatible SQLite files. - With Pro, back up saved documents with their code and data. Nearby sharing can optionally include saved data when both sender and receiver have Pro, with receiver approval. - Improved recovery copies of documents stored on this device and clearer messages when saving fails. - Improved saving of AI-generated documents and fixed result mix-ups and cancellation handling between import windows. - Improved editing of code and AI prompts when the keyboard is open on iPhone. - Improved spacing and backgrounds in Settings and the skin picker on iPhone Duo. - With Pro on iPhone Duo, the JSX preview picker now shows up to five recently used and three recently run documents, without duplicates. - Fixed background refresh initialization when the app starts. - Reduced unused space above the App Introduction heading. - Improved preservation of existing document metadata during startup. - New Pro Office Paper skin, improved text sizing in the app interface and clearer Pro badges in the skin picker. - Removed the retired GitHub Models provider and fixed compatibility issues when importing JSX documents.

Great idea

Suggestion:
You have got the UI/UX down, its appreciable and easy. If this could be a one-stop app for pasting html/js/css from AI, it would be much more versatile than just jsx and serve as code-deck of sorts, maybe even a personal codepen?

Giving this a shot as my main “AI generated code stuff” goes here. I understand the position on ads, though this does mean the app listing accurately does say for free users the app + device ID/advertising data data + ads: which isn’t great any time any category of data is collected for third parties.

Response from developer

Thank you — "my AI code stuff goes here" is exactly the vision: one place for the games and utilities you make across different AI tools. We built it with beginners in mind, so we focused on single-file JSX on purpose — one self-contained file you can run in a tap, and also open, read, and learn from. Several linked files (html/css/js) get intimidating fast, so keeping it to one file is the whole point — and it's why the name says JSX, not Code. We did talk your suggestion through as a team, and we've agreed to keep this direction for now — a deliberate choice, not an oversight. On privacy — a fair thing to hold us to. The free tier shows ads through standard networks (and the advertising ID that comes with them) only after the system tracking prompt. Pro never even starts the ad SDKs, so there's no advertising ID or ad-network contact at all. And your code and creations are never collected by us — they only ever leave your device if you choose to use the AI feature, and then only to the AI provider you pick. Warm regards, The NearbiJSX Team

Love the App but I need a feature

I love the app, and I use it to run the applications I’ve created with Claude. However, no matter how much I’ve changed the code, my app doesn’t save the data I enter. Is there any way to fix this? Claude told me it’s an app issue, because for example I make an app to track a to-do list, close the app, and it doesn’t save the data; it only uses it while I keep it open. I would appreciate it if you could add that feature, and I would even pay for it as an extra. I really appreciate the app, and even more that you read this positive feedback and idea for making my apps run better.
Thanks.

Response from developer

Thank you so much for taking the time to share this. Honestly, this was something we had missed. Until now an artifact only kept your data while it was open, so a to-do list — or anything that saves what you type — lost its contents once the app was closed. It was never anything you did wrong, and no change to your own code could have fixed it. It's thanks to you pointing it out that we discovered this and can make the app genuinely better. We truly, deeply appreciate it. We're now researching the best way to make your data save automatically and still be there when you reopen the app — and stay in sync across your devices for iCloud users. It's our top priority, and we'll get it into an update as quickly as we possibly can. Your existing apps will simply start saving, with no changes needed on your end. The moment the update is ready, we'll reply right here to let you know. Thank you again, so sincerely, for caring about the app and for helping us make it better for everyone. 🙏 The NearbiJSX Team

Great idea, terrible privacy

It would be worth purchasing if it didn’t exfiltrate data to ad companies the moment you open it. Don’t wanna buy an app that even has those sdks and scripts.

Response from developer

Thank you for the honest feedback. It's a fair point, and privacy is a priority for us. The free version is ad-supported, which is how it stays free, and it asks for tracking permission you can always decline. With the Pro upgrade, ads are removed and no information is sent to any ad company at all. The ad SDKs never even start up. If a Pro install ever sent anything to an ad network, we'd treat that as a bug, look into it, and ship a fix as fast as we can. To be transparent about the rest: beyond ads, the only personal data the app uses is a coarse location for the weather-aware greeting on the home screen. It goes to Apple's WeatherKit for that greeting only, never to an ad company, and you can turn Location off for the app at any time. On the "scripts": the JSX rendering engine runs fully offline inside a locked-down sandbox with no network access, so the artifacts you run can't send anything out either. We're happy to answer any other questions. The NearbiJSX Team
