Intelligent apps for specific situations. For beauty studios, they keep track of bookings, deposits and clients’ healing progress. For parents, they help make sense of proceedings concerning child contact and child support.

Welcome to Mertlin — where AI works for you, so you have time for what truly matters.

AI Applications

for Beauty artists

My Beauty Time

complete client management

I’m a certified PhiAcademy artist for PhiIon and PhiBright Microneedling, with several years of experience, including PMU. I’m building My Beauty Time to save us work from the first booking through to healing.

The app automatically sends your client a consent form, an appointment reminder, a request for a deposit, home care instructions and a request for a photo during healing. You have an overview of appointments, payments and treatment history, while your client knows how to care for the results at home. Open to all beauty artists.

Guide to child contact and child support proceedings
Moji rádcové logo

I’m building this app from personal experience. For several years, I’ve been going through proceedings concerning child contact and child support. I had three lawyers, yet I still had to prepare on my own to give evidence in court and answer questions from the opposing party.

Moji rádcové helps you understand the proceedings, organise your documents, keep track of important deadlines and arrive at hearings prepared, so the proceedings do not drag on unnecessarily. The app does not replace a lawyer, but prepares you for things a lawyer often does not help you with.
