Everything you need to join the VivaLynx beta on an iPhone or iPad, from your invitation email to your first bug report.
Before you start
The Apple ID you were invited with, signed in on the device you'll test with
The email address the VivaLynx team used to send your invitation
iOS 16 or later, with at least 500 MB of free storage
A stable Wi-Fi or mobile data connection
Use the Apple ID we invited
The Apple ID signed in to TestFlight and the App Store has to be the exact address we sent your invitation to.
If a different Apple ID is signed in, TestFlight won't recognize your invitation. You'll see a "Redeem code" screen instead of VivaLynx — that's the symptom, and it means the wrong account is signed in.
Two ways out:
Sign in with the Apple ID we invited, then open the invitation again.
Email [email protected] and we'll resend the invitation to whichever Apple ID you'd rather use.
To check which one you're on: Settings → tap your name at the top. The email under your name is your Apple ID.
Install VivaLynx
1 — Open your invitation email. Look for a message from Apple TestFlight or the VivaLynx team, with a subject line like "You're invited to test VivaLynx." Open it on the device you'll test with.
2 — Install TestFlight. If you don't have it, download it free from the App Store. TestFlight is Apple's official platform for testing pre-release apps, and VivaLynx can't be installed without it.
3 — Redeem your invitation. Tap View in TestFlight in the email. If you have a code instead, open TestFlight and tap Redeem. Check you're signed in with the invited Apple ID before you tap.
4 — Install. Find VivaLynx in your TestFlight app list and tap Install. When it finishes, tap Open.
5 — Sign in. Follow the onboarding in the app to create your account, or sign in if one was already created for you.
Turn on Face ID or Touch ID
VivaLynx can offer faster sign-in, but only if biometrics are already set up on your device.
Settings → Face ID & Passcode (or Touch ID & Passcode) — check a face or fingerprint is registered.
Settings → VivaLynx — check Face ID is allowed.
Open VivaLynx, go to User Profile, and turn on biometric sign-in.
If VivaLynx doesn't offer it, or forgets it after you close the app, check those two device settings first. If it still doesn't work, tell us your device model and iOS version.
If your invitation never arrived
Check spam or junk for a message from
[email protected].Check the address matches. The invitation goes to one specific Apple ID — see above.
Still nothing after 24 hours? Email [email protected].
Getting app updates
We ship new builds regularly during the beta.
TestFlight sends a push notification when one is ready.
Open TestFlight, find VivaLynx, tap Update.
Builds expire 90 days after release. We'll reinvite you before that happens. If you're suddenly locked out and nothing else changed, that's usually why — tell us and we'll issue a fresh build.
Telling us what you find
Anything confusing, broken, slow, or worth improving. Small things count — they're often the ones nobody else mentions.
For quick issues, use TestFlight. Take a screenshot (Side button + Volume Up), tap the preview, choose Share → TestFlight, add a short note and tap Submit. Or open TestFlight → VivaLynx → Send Beta Feedback to write without a screenshot.
For anything detailed, anything about your account, or anything sensitive, email [email protected] or use the chat button in the bottom-right corner of this page. We respond within 1–2 business days during the beta.
What to include
What you were trying to do, and what happened instead
Steps to reproduce it, numbered if you can
Your device model and iOS version — Settings → General → About → Software Version
Your VivaLynx build number — Settings → About, inside the app
A screenshot or short screen recording, for anything visual
Your role — Care Recipient, Family Caregiver, or Professional Caregiver
What to leave out
VivaLynx is a HIPAA-adjacent health app, and bug reports get read by several people. Keep real medical details, exact addresses and other sensitive personal information out of screenshots and reports. Use placeholder or test data where you can.
If a screenshot only makes sense with real content in it, crop or black out the sensitive parts before sending.
