Contra and Lovable just ran a challenge: build an appointment business where "can I book?" turns into "you're booked" with as little work for the owner as possible.
We liked the brief because it makes you design both sides at once: what the customer sees, and what the owner has to do afterwards.
Our entry was a horror escape room in New York. The site is a small pixel game that ends in a booking, and behind it the owner gets bookings, a waitlist for sold-out slots and a dashboard, all running on Lovable Cloud.
Choosing a nail color at the salon shouldn’t feel like a timed exam.
You know the moment: you’re staring at a wall of shades, the nail technician is impatiently waiting, and you can feel the pressure to just pick one. Then you spend the next two weeks wishing you’d chosen differently. The worst.
So I built Polly, an express nail studio in downtown Toronto. The problem I wanted to solve: help customers book while giving them time to choose a shade at home that they’ll actually love.

The booking flow lets customers choose their service, polish type, and up to three favourite shades. When they arrive, their shortlist is ready at their station where they can make the final call in person.
On the salon side, the team can see upcoming appointments and shade selections, manage availability, and keep the color collection up to date. It’s less decision pressure for the customer and less scrambling for the staff.
The appointment is express. The colour choice doesn’t have to be. 💅
SoHo is a boutique photography studio in New York, offering private portraits, editorial shoots, and handcrafted photo albums. Its small team has to manage booking requests, session details, discounts, and customer photos while preparing for shoots.
I built SoHo in Lovable to bring that work into one connected experience.
Clients can choose a session, request a date and time, and track their booking status from their account. The studio can review requests, set approval rules, and see AI-assisted equipment suggestions for each shoot. Discounts become available at the right stage of the booking journey.
For custom albums, clients select a cover and place their photos into a digital version of the physical album box. The studio can manage the order and download all submitted photos as one ZIP file.
The goal was simple: help a small studio spend less time coordinating messages and files, and more time making the work its clients came for.

Meet Sam. He runs a highly requested mobile pet grooming van in Denver, but standard booking calendars are quietly killing his margins. Because generic apps let customers pick any time slot they want, Sam spends two to three hours a day zig-zagging across the city in traffic, burning fuel and losing out on actual appointments just to accommodate a messy schedule.
To fix this, I built Paws & Puddle, a web app that solves his geographic routing nightmare before a booking ever hits the calendar. Instead of a basic form, I engineered a zero-click geo-gate. It automatically fetches a user's zip code via location services and dynamically filters the calendar to only show availability for the specific days Sam’s van is already assigned to their neighborhood.
Because forced logins instantly kill conversion rates, I designed a completely frictionless guest checkout. But to ensure long-term retention, the Thank You page features a "Guest-to-Auth" funnel that seamlessly converts their inputted data into an account post-booking, simply by asking the user to "set a password to track your van's ETA."
Backed by a full operator console where Sam can manage custom service zones, assign route days, and trigger automated status emails, this build proves that premium, minimalist design and aggressive problem-solving belong in the exact same app.
