Designing a booking app that protects the calendar.

Product Design UX / UI Design System AI Assistant 2026

GLAMIT business account screen in Hebrew: Galit Moran of Galit Nails, profit for August 2026 of 5,060 shekels before VAT and income tax with a plus 5 percent pill against July, income of 6,240 and expenses of 1,180 broken out beneath it, a row through to expenses and profit, and a list of account sections for personal details, the client list, the bank account, payment methods, bookkeeping and business settings.

GLAMIT client home in Hebrew: a good morning Dana greeting, a search field with a camera icon, a location and filter row, four service categories in terracotta on tinted circles, and upcoming appointments with photos, addresses, times and a Book button on each.

GLAMIT is a dual-sided beauty app. One side is where clients find and book. The other is a smart business management system, where business owners run the calendar, the clients and the income, with an AI assistant working across both. I was the sole designer and owned both sides end to end, from the research to the design system that holds them together.

From the research

82%

Often look for an appointment today

92%

Re-fill a cancelled slot by hand

94%

Say a clear daily calendar is critical

89.7%

Need new versus returning at a glance

Survey of 60 clients and beauty business owners.

The Challenge

Time on one side, income on the other.

Client view

Urgent needs do not wait for business hours. A broken nail before an event, a fill that cannot slip another week. Finding availability on short notice means calling and messaging one business after another, and the answer arrives one reply at a time.

Business owner view

A last-minute cancellation is a hole in the day and in the month. Filling it means messaging regular clients one by one, hoping someone answers in time. Most owners do exactly that, and most of the time the hour stays empty.

Research

The same problem, seen from two ends.

I surveyed clients and beauty business owners separately, to check whether the two problems I suspected were in fact one. They were: the hour one client cannot find is the hour sitting empty in someone else's calendar.

For clients

82%Look for a last-minute appointment often

91%Want same-day or next-day availability as a filter

86%Want to see photos and work style before booking

80%Want location and price range as filters

76%Say seeing a portfolio before booking is very important

For business owners

92%Message clients manually when someone cancels

94%Say a clear daily calendar view is critical

89.7%Need to distinguish new from returning clients

87%Say seeing expected income by day or month is very important

From a finding to a feature

92% re-fill slots by hand

Slot recovery engine

The window opens on its own, and the assistant invites the clients who searched for it.

91% rank same-day first

Availability-first search

The feed opens on what is bookable now, and every result carries its nearest open hour.

94% need a clear daily view

The day, and what it earned

Appointments, revenue and costs share one day view, so the month adds up while it runs.

Competitive Analysis

Everyone fills the hour. Nobody asks who wanted it.

I benchmarked the Israeli beauty apps a business here actually runs on, the general scheduling tools around them, and the global marketplaces that share GLAMIT's model. The Israeli tools manage a calendar and stop there. The marketplaces do fill a cancelled hour, by notifying whoever joined the waitlist first. The question none of them asks is who was looking for that hour.

Who it's for

One app, two sides.

Two people, opposite sides of the same hour.

Dana, the client

35 · Rishon LeZion

A full-time job and three kids. She gives up appointments more often than she books them, because finding an open hour costs more time than the appointment does.

Drives the decision

Availability · Price · Proof of work

Galit, the owner

38 · Nail technician

Her day is usually full. A cancellation is not a free hour, it is income she has no time to chase. She wants the calendar updated in seconds, and then to get back to the chair.

Drives the decision

Simplicity · Automation · Reach

The AI assistant

The work is the assistant's, the decisions are the user's.

On both sides the assistant collapses multi-step work into a single action. For clients it turns a photo and a sentence into businesses filtered on style, area, availability and price, and surfaces an earlier opening when one appears with the reason it fits. For business owners it matches the clients whose recent searches fit a cancelled slot, compares takings across eight weeks to find the weakest day, and composes the outreach to a client who has stopped returning.

Each capability was classified before it was designed, by one question: what may it do without being asked. Anything reversible runs on its own, anything prepared for the user waits at the button, and anything that commits money or closes an appointment is the user's, including the appointments the assistant found itself.

A GLAMIT assistant insight card: Sundays are the weakest day, a reasoning line stating that eight weeks were checked and that Sunday averages 780 shekels while the other days are over 880, a line reading advice only with no promotion going out without approval, and a button offering to build a Sunday promotion. — Eight weeks checked, Sunday averaging 780 ₪ against over 880 ₪ on the other days. The button hands the owner a promotion to approve.

The GLAMIT assistant screen: a header card stating that it knows the calendar, the clients and the money, and that every action touching money stays with the owner; six tappable starter questions covering retention, drafting, scheduling, reporting and pricing; and an answer listing four clients who stopped returning with the date each one last booked, a line explaining that all four were regulars who stopped, and a note that every draft waits for approval before it is sent.

Design system

Two identities, one system.

Many GLAMIT users are on both sides of it, running a business in the morning and booking for themselves at night, one tap apart. So the color is orientation: one component set, one accent token, and a theme per side.

A cancellation, answered in minutes.

92% of owners re-fill a cancelled slot by messaging clients one at a time. So the empty hour carries a price on screen: a cancellation arrives as 180 ₪ lost and 105 minutes free, and the recovery engine starts from that number. It opens the window, finds candidates and explains each one. The owner picks. The owner confirms.

One door, two sides

For clients and for businesses, on the first screen.

2 · The dashboard

GLAMIT business dashboard in Hebrew: profit for August 2026 of 5,060 shekels, up 5 percent on July, with income of 6,240 against expenses of 1,180 and a five month bar chart pairing the two; a needs attention card carrying three items, a client tomorrow at 17:30 the assistant has marked as a cancellation risk, two clients waiting on a reply in chat, and a VAT filing due in fifteen days with three unreceipted expenses; and the day itself, two appointments worth 300 shekels.

3 · The morning

GLAMIT business calendar in Hebrew: a week strip, counters showing three appointments, 450 shekels of revenue and one cancellation, and an assistant card headed two things are waiting for you this morning, with the cancelled appointment, 180 shekels lost and 105 minutes freed, a line saying it filled the slot automatically by publishing it and inviting eight matching clients, two of whom have replied, and a button to view the candidates.

4 · Candidates

GLAMIT candidates screen in Hebrew: a summary card saying the slot was published 18 minutes ago to eight matching clients and two have applied, ranked by fit, and that the chosen client will be confirmed while the others are told the hour is taken; then Yael Ohana marked returning client with six visits and no cancellations, and Shira Cohen marked new, each with a Choose button.

5 · Filled

GLAMIT confirmation screen in Hebrew: a green check, a line saying the appointment was booked for Yael Ohana today at 11:00 for a 105 minute gel build, a green note that 180 shekels are back in the day, a button to view the calendar, and an assistant card saying it has filled three cancellations worth 480 shekels since the start of the month and will keep watching for freed windows.

6 · The day, closed

GLAMIT business calendar in Hebrew after recovery: the counters now read three appointments, 450 shekels and zero cancellations, and the assistant card is headed I closed the cancellation, one thing left, showing Yael Ohana scheduled with 180 shekels returned and the 11:00 hour taken, followed by Noy Shalom at 15:15 who has not confirmed and who cancelled twice in recent months, with a reminder button.

From a photo to a booked chair.

76% of clients want to see the work before they book, and 91% want availability first. So the search starts with a picture already saved and ends at a chair bookable tonight.

1 · Home

GLAMIT client home in Hebrew: a good morning Dana greeting, a search field with a camera icon, a location line for Rishon LeZion with a filter control, four service categories, and a nearby appointments list whose first card offers a classic facial today at 20:00 with a Book button.

2 · The ask

GLAMIT assistant chat in Hebrew: the assistant invites the client to describe what they want or send an inspiration photo; the client replies about a wedding tomorrow and needs the earliest appointment today, elegant and not too expensive, like the attached photo of almond nails; below, a progress card shows three steps, the photo read as short almond, businesses in Rishon LeZion filtered to that style, and a third step checking who is free today and at what price.

3 · The answer

GLAMIT assistant results in Hebrew: the assistant states what it identified in the photo, short almond, natural tone and matte finish, and says it found two businesses that do this style ordered by who is free earliest; the first result card carries an 87 percent match badge, Galit Nails rated 4.8, a reason line about a similar elegant French style inside the requested price range, the nearest opening today at 16:00, and a Book button.

5 · Choosing a time

GLAMIT booking step one of four in Hebrew: a progress bar, a card confirming Galit Nails and a hand gel manicure, the question when suits you, a July calendar with dots on the days that have availability and the second selected, and a free hours block for Thursday listing 16:00 selected under afternoon and 17:00 and 18:00 under evening.

6 · Before paying

GLAMIT booking step two of four in Hebrew: a heading asking the client to check everything is right, a card with the business, the service, the date and the 16:00 time plus a map and address, an amber band warning that cancelling less than 24 hours before the appointment incurs the full charge, a total of 120 shekels, and buttons to pay or change the appointment.

7 · Payment

GLAMIT booking step three of four in Hebrew: a summary row for the booked service, an Apple Pay button, a saved credit card selected with an option to add another, digital wallet options for Bit, PayBox, Google Pay and PayPal, a secure payment note, the 120 shekel total and a confirm and pay button.

8 · Confirmed

GLAMIT booking step four of four in Hebrew: a green check, the appointment received message, a chip with the service, duration and 16:00 time, the business, date and price, a question asking whether to add the appointment to a personal calendar with add and not now buttons, and an assistant card with a maintenance tip about avoiding very hot water and wearing gloves so the gel lasts three weeks or more.

9 · It stays with the client

GLAMIT client calendar in Hebrew: a July month view with dots on the days that carry appointments and the second selected, then the appointments for that day, the first card showing the hand gel manicure at Galit Nails with its address, a warm footer band carrying the date and 16:00 time, a reschedule button and a cancel link, and a second card for a classic facial.

Beyond the appointment

Bookkeeping, inside the app.

Every two months the owner reports VAT, and every deducted expense needs a receipt behind it. The app already knew what the business earned, so I decided it should hold the expense side too. Now the whole period is handled in one place.

The bookkeeping screen for a two month reporting period, showing the client receipts that were issued automatically, the supplier receipts still to be filed, a card for the expenses missing a receipt, the VAT owed with the amounts collected and paid beside it, recent transactions and suppliers. — The screen opens on where the period stands, both sides of the ledger at once, so the owner knows what is settled before doing anything. Below it an expense can be added, what still needs attention appears with its cost and its deadline, and the VAT owed sits beside the two amounts it came from.

The period arrives already assembled, which is where the time is saved. Attention goes straight to the part that still needs a decision, and from there it can be closed and passed to the accountant.

A sheet over the bookkeeping screen confirming the period is prepared: the documents gathered into a single summary file, a button to send them to her accountant, a note that the period is locked but can be sent again at any time, and the option to keep a copy on her device. — The sheet opens over the screen underneath, so the owner keeps their place while checking it. It describes the bundle before anything is sent: how many documents, the single file they gather into, and how they split between clients and suppliers.

It also says the period locks and can be sent again at any time. Saying so at the moment of commitment is what makes the last step easy to take. Sending is the only filled action, and keeping a copy sits below it as a quiet link.

The same system, wider

The owner's side, on a desk.

A nail technician works from a phone. A salon owner with three chairs and a bookkeeper works from a desk. Same tokens, same components, same assistant, laid out for 1440: the bottom bar becomes a sidebar, and the raised AI action moves into it and keeps its violet.

Three screens, enough to prove the system carries. Not a second product.

GLAMIT calendar on desktop in Hebrew: a right-hand sidebar for business, calendar, chat and personal with a violet ask the assistant action pinned at its foot, the day's hours, counters for appointments, revenue and cancellations, three appointment rows carrying status, and a month grid beside them.

The day and the month sit side by side instead of one under the other, and the appointment rows keep the phone's status badges and the assistant's line about the cancellation.

GLAMIT expenses and profit on desktop in Hebrew: four KPI cards for profit of 5,060 shekels up 5 percent on July, income of 6,240 across 34 appointments, expenses of 1,180 at 19 percent of income, and 27 returning clients; a donut of expenses by category beside income broken down by service; a receipts card flagging three expenses without one and 40 shekels of VAT to reclaim; and the assistant proposing a price update for the fill service with the market range it read, marked advice only.

The KPIs answer whether the month is fine, the charts answer why, and the card points at what needs attention. The assistant reads the same numbers and advises on the business.

GLAMIT assistant on desktop in Hebrew: the same six starter questions, the answer listing four clients who stopped coming with their last visit dates, the reasoning line, a note that every draft waits for approval, and a message field along the bottom.

The assistant keeps its own entry point rather than becoming a widget in a corner. Same six questions, same answer, same line about drafts waiting for approval.
