AI assist

Replace five tools with one app.

Notebook + Excel + WhatsApp chats + a paper diary + a separate finance app — that's where most masters live. Custom AI is the one thing that replaces all of them.

Excel for clients
Client cards with photos, full visit history, debts and notes — searchable and AI-aware.
Paper diary or 3 calendar apps
One calendar: day, week, month, year. Drag-and-drop, recurring slots, public booking link.
Finance in your head
Real income, expenses, recurring payments and debts. Monthly totals that just appear.
Manual messaging clients
Share /book — your clients pick a free slot themselves on a beautiful page in their language.
Typing while doing nails
Voice AI: "Add Anna for 3 PM tomorrow" — done. Hands-free booking, hands-free finance.
App in only one language
43 European languages. Your clients see the booking page in theirs. Your AI talks in yours.
A whole working day of admin work, condensed into one calendar and one voice command.
— Built for solo masters and small studios
Inside the app

See it in action.

Three of the workflows you'll use every single day.

Calendar month view Day timeline with client cards Finance dashboard

Calendar that thinks like you do.

Day, week, month and year — every view, one tap away. Drag a booking to move it. Snap to your working hours. Recurring clients reappear automatically.

  • Day · Week · Month · Year — every view
  • Drag-and-drop bookings, no double-booking
  • Recurring slots: "every Tuesday at 10"
  • Banner: next appointment always visible
  • Works offline, syncs when back

Client cards with full memory.

Photos of every visit. Notes about preferences. Outstanding debts. Total revenue from this client. Last 50 visits scrollable. Phone, address, language.

  • Visit history with photos
  • Debts and prepayments per client
  • Personal notes the AI can read back
  • One-tap call, message, rebook
  • Import from phone contacts

Finance that adds itself up.

Every booking with a price logs the income automatically. Add expenses with one tap. Recurring payments (rent, software) appear on their own. Monthly totals — always one tap away.

  • Income auto-logged from bookings
  • Expenses and receipts by photo
  • Recurring payments on autopilot
  • Debts — who owes you, whom you owe
  • Charts: income, expenses, profit

Real app. Real screens.

Actual screenshots from the live app — calendar, finance and analytics. Nothing mocked up.
