NostalgAI

AI photo restoration app — repair, colorize, and upscale old photographs, with zero backend.

The Problem

Old family photographs fade, crease, and lose their color — professional restoration costs real money per image and takes days, and nothing existed that a non-technical person could point at a photo and use instantly.

The Solution

Four AI restoration operations — restore, colorize, enhance, and remove damage
Zero backend — calls Gemini directly through Firebase AI from the device
Offline restoration history stored on-device with ObjectBox
Before/after comparison view and subscription tiers via StoreKit
Multi-package monorepo with build-enforced architectural boundaries

Outcome

Live on the App Store, earning ~$500/month in recurring revenue from a one-month build with zero backend infrastructure.
