What does Phil Stone do?
By day I sell natural stone at Irish Stone — residential and trade across Northern Ireland and the Republic of Ireland, including The Hillsborough Collection.
Outside of that I build software for problems I’ve hit myself — including STOCut, sheet cutting plans from the stock and offcuts you already have. What’s ready, I share. What’s still being tested stays private until I’ve put enough time into it.

Steadfast — free for anyone who wants it
I built Steadfast for me first. I struggle with fitness, food and weight, and I’m a Christian — so the app is Bible-focused on purpose: Scripture and prayer sit alongside workouts, running and food tracking. It also meant I wasn’t paying for multiple subscription apps while I fight that battle daily. It’s still in development, free if you want to use it, and all feedback is welcome. You can install it on your phone like a normal app. It runs on AWS and Google Cloud.
Run coach
Structured walk-to-run programmes with voice cues, a timer that keeps going in the background, and your playlist playing inside the app — YouTube Music or Spotify.
Bible built in
Daily verse, full Bible reading with multiple translations, listen-aloud audio and reading programmes to work through Scripture over time.
Prayer list
Keep prayer requests in one place, go back over them during sessions, and mark answers as they come.
Food diary
UK-focused food tracking with supermarket products, realistic portion sizes, calorie goals for losing, maintaining or building, and meal ideas.
Measurements & photos
Body measurements, progress photos, workout stats and reminders — saved on your device when you sign in, not parked on my servers.
What else is on this site?
STOCut — cutting plans from real stock. DupeStack — branded pack teardowns into bulk actives. Todayworks — UK site diary, photos and handover packs from the phone. CertPing — crew matrix, vault and expiry emails. Horizon and Locktight are private 12-month trials on my own work and money — not advice, not an invitation to invest. The drone library sits beside those — aerial stills and film from places I love to visit.
