Money Manager Expense Tracker - Private expense tracking — everything stays on your phone

by
OinkOink Money Manager is an expense tracker built on one rule: your financial data never leaves your device. No login, no cloud sync, no account wall — budgets, recurring expenses, investments, and visual reports (Net Flow, monthly trends) all stored locally on your phone. It's ad-supported, and Premium (~$1/month) just removes the ads — framed as "buy me a cup of tea," not a feature-gated subscription squeeze. Built solo.

Hey Product Hunt 👋 I'm Grayson, solo dev behind OinkOink Labs. I built Money Manager Expense Tracker mainly because I wanted to learn how to actually build and ship an app — I was curious whether I could take something from idea to the Play Store on my own, and personal finance felt like a good real problem to build around. So this one just... doesn't do that. No signup, no server, no data leaving your phone. Budgets, recurring expenses, investments, and visual reports (Net Flow, monthly trends) — all local. It's ad-supported to keep it free, and if the ads bug you, Premium is $1/month to remove them — genuinely just "buy me a cup of tea," not a feature-gated paywall. Built and shipped solo, so I'd really appreciate any feedback — bugs, feature requests, or just "this budget flow confused me" is all useful. Happy to answer anything in the comments.
