Why the two categories never overlap
Link-in-bio tools grew out of the creator economy. They optimise for a musician sending fans to Spotify or a creator selling a digital product — traffic routing and monetisation, measured in clicks.
Loyalty platforms grew out of retail. They optimise for a café turning a first visit into a tenth — repeat-visit mechanics, measured in redemptions. Different buyer, different problem, so the products never converged.
The business that needs both is the small local one: a barbershop that gets discovered on Instagram and survives on regulars. That customer has been buying two products and paying twice.
What running two tools actually costs
The cheapest honest pairing is Linktree Starter at $8 plus Loopy Loyalty Starter at $25 — $33/month, two logins, two dashboards, and no connection between the page a customer lands on and the loyalty card they could join.
That disconnect is the real cost. When the enrolment QR lives inside the same page your Instagram bio already points at, joining is one tap from where the customer already is. When it lives in a separate platform, someone has to print a sign and hope.
Where the loyalty specialists are genuinely better
Loopy Loyalty, Stamp Me and the other dedicated platforms issue native Apple Wallet and Google Wallet passes. That means lock-screen notifications and a card that sits next to the customer's payment cards. Bioflow's loyalty cards are web-based and do not do this today.
If lock-screen reminders are central to how you plan to bring people back, buy the specialist. That is a real capability gap and no amount of price advantage closes it.
