Oh Time

Are you also deeply trapped in the time black hole of “endless scrolling”? You intended to put down your phone after watching this video, yet the next automatically playing video captured your attention—only to realize, after repeating this cycle, that you’ve spent a large chunk of time on your phone without even knowing exactly how long. This app was designed precisely to address your “blurred time perception.” “Oh Time” is a floating mobile usage time tracker, built to heighten your awareness of time passing during smartphone use. ---------- Key Features: 1. Floating Persistent Timer: Upon launch, a “persistent timer” appears. With simple interactions, you can record usage duration for your phone or individual apps—no need to frequently switch between apps. 2. Intuitive Data Visualizations: Automatically generated charts clearly display your daily/weekly smartphone usage distribution. See at a glance where your time goes—and how much time you spend there. 3. Green Software—No Permissions Required: Collects no private data. Lightweight and clean—safer and more trustworthy to use. ---------- How “Oh Time” Differs from Built-in Screen Time Tools: Built-in screen time trackers operate retrospectively. For example, while actively using an app, you remain unaware of how long you’ve been using it—only learning, after the fact, that you wasted substantial time daily on certain apps. In one sentence: We focus on the process; other tools focus only on the outcome. ---------- Contact Us: If you have suggestions or feedback, please leave a message via the in-app channel—or email us directly at: shouheng2020@gmail.com.
