We build software, then we run it.
dev-test.uk is the software development arm of the Colloquize group. Two of our own products are live today: ticketFOMO, ticketing for small venues, and TherapyDesk, booking and practice management for therapists.
ticketFOMO, 60-second filmMusic, no speech
What's in the film
An animated tour of the nights ticketFOMO sells tickets for. It opens on "Tonight. Live. Loud. Yours." and "Small rooms. Big nights.", then moves through rock ("Loud. Sweaty. Unforgettable."), EDM ("Bass. Lights. No sleep."), comedy ("Laugh till it hurts."), drama ("Feel every scene.") and stage shows ("Lights up. Curtain up."). Four quick cards follow: discover (a feed made for you), book (official tickets, better prices), resell (verified and safe) and relive (memories of every night). It closes on "Don't miss out." with the ticketFOMO logo, "Small venues. Big nights." and App Store and Google Play buttons. Music, no speech. Read the timed transcript.
A short tour of the app. "Everyone's going. Your friends. Your feed. Except you?" The ticketFOMO logo with "Never miss the night: discover, book, resell, relive." Then "Made for you": a feed that learns what you love. "Official tickets": better prices than standard listings, with secure in-app checkout. "Can't make it?": resell with trust built in, verified ownership and a chat with the seller. "Relive it": every event becomes a memory, organised by category. It ends on "Don't miss out." Music, no speech. Read the timed transcript.
Real screens from the app, scene by scene. "Booking that feels effortless": clients pick a treatment and an open slot at any hour. "Never double-booked": live availability matched to opening hours and every therapist's calendar. "Every transaction, protected": card details never touch the server; payments run through SumUp, Stripe, PayPal or Square. "Every client, seen": intake forms, history and notes together. "On time, without chasing": automatic confirmations and reminders. "Gifting, beautifully made": printed or digital gift cards. "Your practice, clearly": bookings, revenue and returning clients in one view. "Your clients' data, guarded": encryption at rest, two-factor sign-in, a full audit trail and daily backups. It closes on "Your practice, calmly in order." Original generated score, no speech. Read the timed transcript.
Ticketing for small and mid-size venues: the gig in the back room, the comedy club, the 200-seat theatre. Venues sell official tickets; fans find nights they'll love and pass tickets on safely when plans change.

Software that ships with proof.
The habits behind both products, and behind this site. If it isn't tested, it isn't done.
- Checked before it leaves the laptop
- Type checks, unit tests and a smoke test against a scratch database run before every push.
- Tested in a real browser
- End-to-end tests drive the apps the way people use them, from signing in to checking out.
- On brand, every time
- A brand check compares logos, colours and type against each product's guidelines and stops a release that drifts.
- Released in one step
- Each release goes live in a single switch, keeps the last five for rollback, and rolls itself back if the live check fails.
- Secure by default
- Two-factor sign-in, encryption at rest, audit trails and daily backups, backed by Colloquize's data security practice.
- Watched after launch
- A daily monitor checks every site is up, its certificate is healthy and private files stay private.
