How to Invite Your Partner to a Household App (Links That Actually Work)
Universal HTTPS invite links, App Store fallbacks, and token security for partner onboarding—how FairShare handles culi.app join URLs.
Why custom URL schemes fail partners
`myapp://invite` links break in Messages previews, email clients, and when the app is not installed yet. Partners abandon setup before the first shared card exists.
HTTPS universal links on your marketing domain survive taps from any app and can fall back to a web page with App Store CTA.
FairShare invite format
Partners receive `https://culi.app/apps/fairshare/join?token=…` with matching deep link fallback `fairshare://join?token=…` documented in product FAQ.
Tokens map to Supabase-backed accept flows with TTL and household isolation so old links expire safely.
Start solo, invite when ready
FairShare supports solo onboarding—capture Brain Dumps and stabilize your board before sending an invite when the rhythm feels sustainable.
Messages and WhatsApp shortcuts in the invite sheet reduce copy-paste friction on day one.
