There's usually something in testing. Real builds, shipping most days, and a direct line to tell me when something's wrong — which is the entire point of a tester.
One email puts you on it. You'll get a link whenever something new opens up for testing — on iPhone, Android, or both — and nothing else. No newsletter, no drip campaign.
Exact Print Studio — print envelopes, photos, labels and business cards at exactly the size you asked for. Email me and I'll send the TestFlight link straight back.
Life and Invoice Maker for Trades are out. You don't need a tester spot for either — they're on the store like any other app.
No. Testing is free, always, and nothing is ever charged to a tester.
Nothing — there's nothing to do. Life has no accounts and no server of mine. What you type stays on your phone unless you connect your own Google Calendar or Tasks, and that goes to Google, not to me.
Sometimes. That's what beta means, and it's why the in-app "something off here" button exists — it writes the report for you, two taps to send. Those reports are the single most useful thing a tester can do.
No. Your data lives on your device and carries over.
Almost always one of two things. Either the join email went from a different address than the Google account on your phone — that's the common one — or Google just hasn't caught up yet. Check the account first, then give it a few minutes and reload.
