Piranha: shooting range hit marker 1.0.0

for Sony Xperia XZ1 Compact

With this app you can mark the hits with a spotting scope and thus avoid unnecessarily changing targets and save time and money in the process.
This works as follows:
- A smartphone is attached to a spotting scope using an adapter so that the target is clearly visible on the screen.
- Little by little you can mark the hit series and look at them later.
