What you need
- An Android phone running Android 8.0 or newer, with a rear camera.
- A laser training pistol or a laser training cartridge. Red or green both work.
- A printed target. The app’s targets print on ordinary letter paper.
- For a room-to-room course only: a Mac or Windows computer to run the free hub, and all devices on the same WiFi.
Shoot House is a dry-fire tool. Use it only with an unloaded firearm or a dedicated training device, and follow your own safety rules — the app does not and cannot verify that a firearm is clear.
Common problems
- Hits are not registering
- Re-run the target calibration so the app knows where the target’s corners are, and check the laser colour is set to match your device. A very bright room, or sunlight falling directly on the target, can wash out the flash — shade the target or lower the room lights.
- Shots register where I did not shoot
- Something else in frame is flashing — a TV, a phone screen, a reflective surface bouncing the laser. Move it out of the camera’s view, or narrow the framing so only the target is visible.
- Scores look wrong on printed targets
- Print at 100% or “Actual size”, never “Fit to page”. The ruler bar on the sheet must measure 100 mm. Scaling the print moves every scoring zone.
- Phones cannot find the hub
- Every device must be on the same WiFi network, and the hub must be allowed through the computer’s firewall — on Windows, tick Private networks when it asks. Guest networks and networks with client isolation will block phones from reaching the hub.
- The hub will not start
- If it says the port is already in use, the hub is most likely already running — look for its window before starting a second copy.
