I'm publishing 6 MEP mobile apps to Google Play, built for detailers and field engineers. Before they can go live, Google requires 12 testers opted in for 14 days. All you need is an Android phone and a Google account. Every app is just $0.99 during initial testing.

How it works

Four steps. Two minutes.

1

Send me your Google email

I have to add you to the approved tester list first, or Play will show the apps as unavailable. Use the email tied to the Play Store on your Android phone.

2

Scan or tap an app below

Scan the QR code with your phone camera, or tap the "Become a Tester" button if you're reading this on your phone.

3

Opt in and install

Tap "Become a tester" on the Google Play page that opens, then install the app. Sign in with your Google account if prompted.

4

Keep it for 14 days

Google's counter only counts testers who stay opted in for 14 consecutive days. Use it in the field, break it, and email me what you find.

⚠️ Important: email me your Google account first

The QR codes only work after I add you to the approved tester list. Email jergrif73@gmail.com with the Google account on your Android phone (Gmail or Google Workspace) and I'll get you added right away. Apps are $0.99 during initial testing. Android only for now.

Pick your apps

Six apps. Test one, test them all.
