I'm Chris. I build practical software for schools, venues and small business — bells and PA that ring on time, screens that run themselves, quotes you can send from the driveway. Plus a few made purely for the fun of it.
Set-and-forget tools that run all day on their own. Each one has its own site with the full manual, screenshots and setup guide.
Run your school's bells, music and announcements from an iPad. Build the timetable once, plug into your PA, and it keeps ringing on time — through terms, holidays, assemblies and wet-weather days.
Turn an iPad into the server that drives every screen in the building. Drag in photos, video and notices, schedule what shows where, and the TVs keep playing even if the iPad walks out the door.
Turn any TV into a proper digital menu board for a cafe, pub or takeaway. Build the board on your iPad or phone, hit publish, and the screen updates over your own Wi-Fi. Change a price in seconds.
Quotes, invoices and job notes for tradies. Knock out a professional quote on site, add photos and materials, and send it before you leave the driveway. GST, deposits and payment terms handled.
Scheduled announcements, background music and chimes for libraries, pools, shops and community centres. Record it once, set the times, and the venue looks after itself — with a phone remote for live callouts.
A lockdown and evacuation PA that anyone on staff can trigger from their pocket — including a silent alarm. Pre-recorded doctrine, live voice override and a clear all, running on your own network.
Your own media server. Movies, TV, a shared music jukebox and photos on every telly, phone and tablet in the house — with artwork pulled in automatically. No subscription, no cloud. Completely free.
Wireless screen mirroring for classrooms, meeting rooms and venues. Cast to Android TVs, Fire TVs and touchscreen panels over your own network — annotate on top, no internet required.
Fast, simple video and photo editing — trim, crop, caption and export in seconds without wading through a timeline. Free to try, with a single one-time unlock for the lot.
Little apps built to scratch an itch — and finished properly anyway.

I've spent years installing and fixing audio, PA and display systems in schools, pools, libraries and venues around Melbourne. Most of these apps started as something a site actually needed and couldn't buy — so I built it, then finished it properly.
Every app here is meant to run unattended in a real building — a school office, a bar, a ute on a job site. That means sensible defaults, no surprise cloud outage, and behaviour you can predict at 8:45 on a wet morning.
Need something similar for your site, or a tweak to one of these? Have a chat with me — most of them started exactly that way.
Questions about any of the apps, support, pricing for a site licence, or an idea you want built — send me a note. I answer my own email.
