Hi everyone, I’m a solo dev working on a utility called **FrameForce**. I wanted to create a tool for mobile gamers to stabilize frame pacing and customize overlays without needing to root their devices—which was a massive technical headache to get working smoothly.

**The Tech Stack & Challenges:**

* **The Overlay:** I’m using the `SYSTEM_ALERT_WINDOW` permission to handle the crosshair. The main challenge was minimizing input lag and ensuring it doesn't get killed by Android’s aggressive battery management.
* **FPS Stabilization:** I’ve implemented logic to monitor frame latencies and attempt to stabilize the render thread. I’m currently testing how this interacts with different GPU drivers (Mali vs. Adreno).
* **Hardware Compatibility:** It’s built to be lightweight, but I’m seeing inconsistent results on devices with 4GB RAM vs 8GB RAM.

**How to test it:**

Since Reddit filters often remove direct APK links, I have hosted the beta on **itch.io**. You can find it by adding the link below to your browser :

I’d love to hear your phone model and if you notice any "ghosting" or lag with the overlay active. Thanks for helping a solo dev out!

**Transparency & Safety:**  
I know sideloading is a risk. I have posted the **full VirusTotal scan report and SHA-256 hash** directly on the [**itch.io**](http://itch.io) **project page** so you can verify it before downloading.
