I got tired of it.
Every time I opened a budgeting app, it felt like walking into a shopping mall: flashy banners, “Go Premium” pop-ups every three taps, subtle trackers humming in the background, and that quiet guilt of knowing my spending data was probably being sold somewhere.
I just wanted to record my expenses in peace. Was that too much to ask?
So one day, I decided to stop complaining and start building.
That’s how JitterPay (钱跳跳) was born.
JitterPay is a completely free, open-source Android budgeting app. No ads. No subscriptions. No data collection. No “pro version” waiting to lock the best features behind a paywall. What you download is what you get — and it’s fully featured from day one.
What makes it feel different the moment you open it?
A clean, buttery-smooth Material You interface with delightful micro-animations
Lightning-fast transaction entry (seriously, it feels faster than most paid apps)
Smart search that actually understands what you’re looking for
Custom avatars for your accounts so your wallet, credit card, and cash feel personal
Automatic background updates that respect your time (you can snooze them if you want)
Deep privacy: nothing phones home, ever
But more than the features, it’s the feeling.
It feels like the app was made for you, not for an investor’s KPI dashboard. There are no dark patterns. No fake scarcity. No psychological tricks. Just honest, respectful software.
Building it taught me something profound: when you remove the pressure to monetize, you suddenly have the freedom to obsess over details most apps never bother with — the perfect spring animation on a checkmark, the subtle haptic feedback when you hit budget, the way the balance number gently scales when it updates.
This project is my answer to the question: What would software look like if we built it purely out of love and respect for the user, instead of extraction?
If you’re tired of noisy, manipulative apps and want something that simply works beautifully, I’d love for you to try JitterPay.

I’d also be incredibly grateful for any feedback, bug reports, or even just a star if it resonates with you.
