Choosing a tool
Most lash artists already have a booking app, so the real question is whether anything on your screen is watching the fill interval.
The tools below are the ones that come up when a lash artist starts looking for software: full front of house systems for beauty professionals, wide salon and spa platforms, and general booking tied to a card reader. They are all built to take an appointment and take a payment. LashRetention is built for the gap after that, when a client who should sit down again in three weeks quietly turns into a client who books again in seven.
These pages are written as fit questions, not scorecards. Each one describes what kind of operator the other product is built for, what shape of workflow it assumes, and which lash studios are better served by it. Where the honest answer is to keep your current booking system and add fill cycle tracking beside it, the page says so. We do not publish other companies pricing or feature lists here, because those change and you should read them at the source before you decide.
LashRetention vs GlossGenius
GlossGenius is built for an independent beauty professional who wants booking, checkout and client marketing in one place, while LashRetention is built for the artist whose calendar already works but whose fill interval keeps slipping.
LashRetention vs Vagaro
Vagaro suits a studio with several service categories, staff to schedule and a front desk to run, while LashRetention suits the artist whose only real problem is that fills keep landing in week six.
LashRetention vs Square Appointments
Square Appointments suits a lash artist who wants a straightforward calendar sitting next to her card reader, while LashRetention suits the artist who needs to know which clients are sliding out of their fill cycle before they go quiet.
Free tools
Two working calculators for the numbers that decide whether a lash studio pays for itself: what a set costs you, and what your bed can actually carry.
Working document
One page per lash client that turns guesswork about her rebook date into a record you can read before she sits down.
Every product named on this page can hold a lash appointment and take a card. Only one of them counts the days between a set and its fill and tells you which clients are drifting toward a rescue set. Book a demo, bring the shortlist and your own client list, and see the fill cycle record before you commit to any of them.
