Hi HN,

I’m Wesley, an Android dev from São Paulo, Brazil. In 2023 made a commitment to launch real products and after 2 failed attempts an app that started as a simple clock turned into a huge project that I have been working on for 2 years.

---

### What it does - *Auto-launches* whenever the phone is docked or charging. - Supports dozens of usecases with multiple clocks, customizations, utilities and basically infinite possibilities with 3rd party widgets. - *Duo & quad layouts* for tablets/large screens, fully resizable and rearrangeable - *Burn-in grid, sleep timer, night mode* so it can be used for a long time - *Media controls* for Spotify/YouTube Music, and about 90 other apps. Works as a remote. - And much more!

---

### Tech bits - 100 % *Jetpack Compose* with MotionLayout + custom GLSL shaders. - Falls back to *DreamService* (Android’s official screensaver API) on devices that support it. - Telemetry is limited to crash/analytics events; no ad SDKs in the core experience.

---

### Traction so far - Bootstrapped; launched mid-2023. - *1 M+ installs* and a *4.7 rating* (in Brazil, varies for each country) on Google Play.

---

### Monetization Free tier includes core clocks & widgets; *Pro* unlocks extra features, weather and other things.

---

### Why I’m posting I’d love feedback on:

1. Feature ideas, UX improvements, etc 2. Bugs, specially in different form factors.

Happy to answer anything—technical deep dives, business questions, code snippets, you name it.

Thank you!
