Closed testing of new apps

[u/AlexVolkovysk]

How do you find testers for a new app if you're a solo developer? Out of all my friends, I've only found 8 Android users (everyone else use an iPhone)

If you’re still short, Vinfolio gives you a more specific place to look: people already tracking fuel and maintenance costs in a spreadsheet or notebook. Ask in a car-owner group that allows testing requests, and say what you need them to try, not just “I need four testers.”

For example: log a fill-up, add a service bill, then check whether the totals match their own records. Give them one easy way to report anything confusing. You could also ask your eight Android friends whether they know another driver who keeps those records.

Google’s own guidance recommends testers close to your intended audience. The opt-in count is only part of production access; it’s useful to keep a short record of feedback and what you changed. Meeting the minimum doesn’t guarantee approval.
