Fainto: Private Budget Tracker

Hey Product Hunt 👋
I'm Mohsen, Android Tech Lead and AI enthusiast. I built Fainto because I wanted an AI finance coach and couldn't find one I'd trust with my own bank data.
The problem with every AI budgeting app
Cleo, Rocket Money, Copilot — they all work the same way underneath. Your transactions get uploaded, an API call goes out to a model provider, and advice comes back. Your salary, your rent, your debts, your medical spending: sitting on someone else's server, protected by a privacy policy that can change tomorrow.
I didn't want "encrypted in transit." I wanted it not sent at all.
So the AI runs on your phone
Not a marketing claim — an architecture. The model executes on your device. Put Fainto in airplane mode, and the coach still answers your questions.
🧠 Five on-device models, from a 135M lightweight one up to Phi-4 Mini (3.8B), so it adapts to a budget phone or a flagship. ~10 tokens/sec, locally.
🔒 Zero bytes uploaded by default. No account, no email, no sign-up. Open it and start.
🌍 A 45-country tax engine — real income tax rules, not a US-only calculator. 25 languages.
📴 Fully offline. Plane, subway, bad signal, doesn't matter.
🚫 No ads. No trackers. No bank connection.
Why nobody else does this
Getting a 3.8B-parameter model to run inside an Android app's memory budget, at usable speed, without cooking the battery, took months of quantization and memory work. Shipping an API key takes an afternoon. That's the entire reason the "private AI finance app" category is empty.
Where it honestly stands
It's early. Solo project, Android-first. iOS is the most-requested thing, and I'm listening. I'd especially love to hear from anyone who's abandoned a budgeting app because they didn't want to link their bank — that's exactly who I built this for.
Free on Google Play. Happy to go deep on the on-device LLM side if anyone's curious — AMA.
