Cross-platform apps that feel native, built from one codebase and shipped to both stores. Our longest mobile engagement ran 18 months, across five production releases, in a client's repos, kept on because the work held up.
- Ionic, Capacitor and Expo
- Offline resilience and realtime sync
- Both store submissions handled
what we build
What Goes Into a Mobile Build
New apps and apps we keep releasing after launch. The household platform is client work we ran for 18 months. NutriHygiene is our own nutrition product, not a client endorsement.

- Ionic React, Capacitor and Expo / React Native
- Realtime sync and offline resilience
- Subscription billing and trial paywalls
- Device features: calendar, camera, notifications
- Kiosk and tablet builds alongside phones
- Both App Store and Play Store submissions
- Over-the-air updates and monitoring
how we work
How a Mobile Build Goes
Scope
A free call and fit review. Once the features and release requirements are clear, we agree a written scope, timeline and quote before paid work starts.
Design & build
Figma-first design, then a cross-platform build the same team ships.
Test
Real-device testing, offline cases and billing flows, before anything goes near the stores.
Launch & maintain
We handle both store submissions. What we keep releasing after launch — store updates, monitoring, over-the-air fixes — is written into the quote. Otherwise we hand it over with documentation.
“I was blown away by the professionalism and commitment of the Prograsec team. They took on a project that was outside the standard functionalities and custom-coded a solution that perfectly fit our needs. Their expertise and attention to detail ensured we met our launch date on time. Can't recommend Prograsec enough!”
questions
Before we start
One app for both iOS and Android?
Yes. We build cross-platform from one codebase with Ionic/Capacitor or Expo, so you get both stores without maintaining two native apps.
Can you handle the App Store and Play Store submissions?
Yes, both. We've shipped a European app suite through five major releases, so store review and release management are familiar ground.
Do you build tablet or kiosk apps?
Yes. One engagement was a wall-mounted kitchen touchscreen plus companion phone apps, all from one codebase.
How much does a mobile app cost?
A basic single-purpose app sits at the low end; anything larger is scoped. You get the exact figure in writing before you commit.
Is NutriHygiene a client project?
No. It is our own nutrition product. The household productivity platform is client work under NDA, and that is the 18-month retained engagement.
Who handles store updates after launch?
Whoever the quote names. Ongoing release and maintenance is a separate, written arrangement, not an unspoken extra. If you want a clean handover instead, we document it and step back.
