I built a mobile AI image editor using nanobanana & gemini 3 pro image – 2 months free generations for Reddit

Hello everyone,

tldr top note: I built this mobile app for my own use, now published it on app store & play store, and giving free personal use until end of January 2026 (uses nanobanana2 / Gemini 3 Pro Image preview).

How to join? Download the app on ios or android, do not subscribe, open the account page, enter REDDITBANANA code and submit. that's it. If you use up your credits send me a dm and I will refill.

You can download here: https://photopatcher.app
AppStore link: https://apps.apple.com/us/app/photopatcher-ai-photo-editor/id6755049629
GooglePlay link: https://play.google.com/store/apps/details?id=app.photopatcher

I built this as a side project, used it myself for a while, I almost entirely use ai image editing on the go instead of on computer, like quick edits on my wife's cafe, putting objects around, or when eating with my kids adding video game effect on top of them if they finish their food etc.

When nanobanana2 came out I decided to polish the app a bit and release it incase other people would like it as well. I have credits available for the next couple months, so sharing with the community.

Privacy: You dont need to signin/login. App doesnt save any of your input or output images. All of them are directed to gemini and returned directly to you. I dont save any image on backend.

What does app do? App has 2 workflows: 1) my custom workflow where I draw patches on certain regions to edit. 2) classic mode where its basically like using gemini- you enter prompt, image references, ratio and submit. This part is for users that dont care for the custom workflow and just use with their own prompts.

Limitations: I don't intend to limit anything, obviously entire generation is done on gemini side, so their censoring etc still applies. I would have to limit anyone using beyond personal usage but if you are not generating hundreds of images per day its fine. Even though my rate limits are high the model is still a preview model so google might restrict it from time to time.

Requirements: Nothing, you don't need to do anything in return.

The only advantage for me is my app will have some download numbers. Also if you like the app I would appreciate any reviews on appstore/playstore but this is COMPLETELY OPTIONAL, only if you like it. I created some subscriptions on the app for after the credits phase, but they are almost the same price as actual costs. I would appreciate any feedback for improving the app. You can dm me or reply here.Also if you need any certain aspect that would ease your everyday life let me know I can implement and add it to the app. It's good for me to improve it after all.
