Hello everyone. I am a developer and HLL player. I have finished building a new Artillery Calculator and I am looking for 12 testers to complete the Google Play requirements for production.

Some features:

* **Full Faction Support:** Precise MIL calculations for US, German, and Soviet forces. Works for both standard howitzers and mobile SPA (Self-Propelled Artillery).
* **Combat-Ready Input:** Custom-built keypad designed for fast distance entry during heavy fire missions. No clunky system keyboards.
* **Tactical Dark Mode:** High-contrast, low-light interface to keep your eyes adjusted to the screen during night maps.
* **Haptic Feedback:** Optional vibration on keypress so you can confirm inputs purely by touch without losing focus on the frontline.
* **Keep Screen On:** Dedicated toggle to prevent your phone from locking, so your fire solutions are always visible when the spotter updates the mark.
* **Total Offline Reliability:** Zero lag and no data usage. All calculations happen locally on your device, even without a connection.

If you are interested in helping, the process is:

1. **Join the testing group:** [https://groups.google.com/g/hll-app-testers](https://groups.google.com/g/hll-app-testers)
2. **Download the app on Google Play:** [https://play.google.com/store/apps/details?id=com.kishinnext.artycalc](https://play.google.com/store/apps/details?id=com.kishinnext.artycalc) 
3. **Download the app using the web**: [https://play.google.com/apps/testing/com.kishinnext.artycalc](https://play.google.com/apps/testing/com.kishinnext.artycalc)

I am looking for honest feedback to improve the tool for the community.



Thanks for your time.
