Our Apps Work with Us

Our Apps

Showcase — Live in Production

Developed for real users across iOS and Android. Both are fully instrumented, production-grade Flutter applications — not prototypes. Complex algorithms, engagement mechanics, Cloud Functions pipelines, subscription management, and zero crashes.

My 12-Step Coach

My 12-Step Coach

Recovery structure in your pocket

A production-grade habit formation platform built on Flutter and Firebase. The technical challenge here was not content — it was behaviour change engineering at the app layer.

  • Onboarding wizard with complex state management — delivers an experience, not a setup form
  • Insights engine using z-score analysis to surface behavioural patterns with progressive reveal — complex data, no overwhelm, non-shaming language throughout
  • Habit loop mechanics: streak state management, victory badge system, smart nudge timing via FCM
  • Dormant-user re-engagement: detects drift and intervenes before churn
  • Firebase Analytics with sobriety cohort segmentation across 14 fellowships
  • Home screen widgets (iOS WidgetKit, Android Glance)
  • In-app subscription management, sharing mechanics with accountability signatures
  • Zero crashes in production

Surplus

Surplus

Financial clarity for households

A financial situational awareness platform with a custom algorithmic insights pipeline. The complexity is in the intelligence layer — five insight types, each with distinct detection logic designed to surface behavioural patterns without triggering anxiety.

  • Buffer engine: forward-looking runway calculation across linked accounts and obligations
  • Insights pipeline (Cloud Functions): Locked Income, Merchant Concentration, Recurring Cost Drift, Surplus Retention Rate, Financial Drift Timeline
  • Entropy detection for cost drift — YoY merchant-level comparison (sigma logic rejected: too noisy)
  • AI transaction categorisation (Claude Haiku) via OCR photo capture
  • Non-judgemental, observational output language — regulatory-safe by design
  • Household real-time sync, home screen widgets, onboarding wizard
  • Zero crashes in production

Studio

Have an idea for an app?

If you have a focused problem that deserves a focused app, we'd like to hear about it.

Flutter — iOS & Android from one codebase

Both our apps ship on iOS and Android from a single Flutter codebase. Faster to build, easier to maintain, consistent experience across platforms.

Production-grade from day one

Firebase backend, Cloud Functions, push notifications, subscription management, analytics instrumentation, webhooks, managed assets. Not MVPs — properly engineered software.

Founded by a high-performance operator

Stuart MacCormack is a Chartered Engineer with 25 years across military command, strategy consulting, and large-scale technology operations. He scaled Amazon's cross-border inventory programme from $12Bn to $24Bn, launched a new selection product from zero to $1Bn in 15 months, and delivered board-level transformation programmes at KPMG-McLaren across BP, BG Group, and Alltech. Previously a British Army Major who commanded engineering units on operations in Iraq. Apps are built to perform — not just to ship.

Small, focused engagements

We don't take on projects we can't give full attention to. If we say yes, we mean it.
