About this app

**KNOWN ISSUES** We have discovered that the latest android engine causes an issue with some users not being able to get past the initial screen. This is due to the new way permissions are authorized. To fix this, you will need to go into your phone’s app settings, locate Trasol and manually allow all required permissions. We are working on an update to address this issue.

Required Permissions:
• Camera: This is needed for the HUD display.
• Location: This is required for auto accessing atmospheric conditions and altitude.
• Microphone: This is for recording shots.
• Storage: This is required to save pictures and rifle / bullet profiles.
All permissions can be set to only use while app is in use.
Thank you,
Trasol development team

So got this and used it during a long range class put on by Snipers Hide. Running on my older S5 Active, it was pretty damn accurate. I usually only needed some minor tweaking to get solid hits at 1000. The day I got a new S9, the program would not run. Thought I was screwed. Read thru the reviews, and a user said you had to enable all the permissions... seeing it was dated in 2019 I figured I'd try it. IT WORKED! Manually turning on permissions in app settings worked for me.

This app worked great on my S5 but can't get past the splash screen on my new S21. I don't think it's being updated so it's time has come to an end. Update 1/25/2022 - It appears this app just isn't being updated to conform to Google's runtime permissions requirement. Works on one device but not my S21 following system update.

Greg, we are sorry to hear you are having problems. We have discovered an issue in the latest Android update that we are working on fixing. To fix the problem now, you will need to go into your app settings, find Trasol and then manually allow all permissions.

Bought this app shortly after it launched. Use it for years with no problems. All of a sudden, over the last year it has refused to work. I've tried it on different devices and then waited for them to update it, but I think I'm going to give up because these people obviously don't care about their app.
