Three seconds to record what you spent

FirstTick
A pair of friendly eyes that keeps you focused

In review - coming soon
Availability, platform versions and features on this page describe the release we are currently submitting to the App Store, Google Play and the Mac App Store.
How we build
Four rules that shape every screen we ship
Private by design
Your data is written to storage on the device. We do not run a service that collects it, so there is nothing of yours in our data centre.
Local by default
Your data is kept on your device, not on our servers. The mobile applications work fully offline; WinOps Toolkit reaches the network only for the sessions you open.
Fair, simple pricing
Where an application has a free version it keeps working forever. Upgrades are a one-time purchase or a clearly priced subscription that stays with your store account - never a dark pattern.
Answered by people
Support is handled by the same team that writes the code, in the languages published on this website.
About Us
A small team shipping small software
YingZhiChu is a software product studio registered in Beijing. We started in 2015 building systems for clients and, over time, moved our attention to products of our own: applications that we design, develop, test and support end to end.
Our mobile applications are written with Flutter or with native toolchains - SwiftUI on iOS and Kotlin with Jetpack Compose on Android - and the desktop application WinOps Toolkit is a native macOS app written in Swift with SwiftUI and AppKit. Go also powers the tooling behind all of them. We deliberately keep each product narrow - one job, done properly - because the apps we liked least were always the ones that tried to do everything.
We do not sell user data, we do not run advertising profiles across apps, and we publish the details of what each application stores and where. Our mobile applications are currently under review for the App Store and Google Play, and WinOps Toolkit for the Mac App Store; if you already use one of our builds and need help, the contact details below reach the people who maintain it.
Our Mission
To make everyday record-keeping so quick that people actually keep doing it, and so private that they never have to think about it.
Our Vision
A portfolio of small tools that each do one job better than the oversized applications they replace.
