Questions per survey
One codebase. Two app stores. A dataset that shapes education.
Triptelligence® gives teachers a structured voice on everything that happens beyond the classroom — educational visits, sport, extracurricular activities. Teachers answer five quick questions twice a week. Results land the next day, benchmarked against peer settings.
Points and streaks keep engagement high. The goal: aggregate real teacher opinion into a dataset that shapes how the education sector plans and invests in experiences beyond the school gates.
Evolve Advice Ltd needed a full-stack, mobile-first platform that could collect structured feedback from teachers at scale. The app had to work natively on iOS and Android while keeping development costs proportional to an early-stage product budget. It needed real-time survey delivery, same-day result processing, gamification, and a separate admin backend for managing schools, users, and content.
Strength 9 built the entire platform from scratch — the teacher-facing mobile app, the admin backend, the database, the authentication system, the infrastructure, and the CI/CD pipeline — all from a single developer, all shipping to iOS and Android in September 2026.
Evolve Advice Ltd
Evolve Advice Ltd is the company behind EVOLVE — the UK’s leading educational visits management system. They provide guidance, software, and expertise to help schools plan and approve learning outside the classroom safely and confidently.
Building separate native apps for iOS and Android means two codebases, two build pipelines, and twice the maintenance burden — a cost structure that rarely makes sense for an early-stage product. The challenge was delivering genuine native behaviour on both platforms: safe-area-aware layouts, bottom sheet navigation, home screen installation — at a fraction of what two separate native apps would require to build and sustain long term.
What We Built
- Teacher-facing progressive web app (iOS, Android, and web)
- Admin portal for managing schools, surveys, users, and content
- Survey engine delivering two 5-question surveys per week per teacher
- Same-day result processing and school benchmarking
- Points, streaks, and rewards engine
- Better Auth with isolated authentication pools for admin and teacher users
- DigitalOcean Spaces CDN for media storage
- Automated CI/CD pipeline via GitHub Actions, path-triggered per app
- Nginx reverse proxy on a DigitalOcean Droplet
One codebase, three platforms.
Rather than building separate native apps for iOS and Android — two codebases, two build pipelines, twice the maintenance — we built a single SvelteKit 5 progressive web app and wrapped it with Capacitor for native distribution. One codebase ships to the web, the App Store, and Google Play simultaneously. Teachers get genuine native behaviour: safe-area-aware layouts, bottom sheet navigation, home screen installation. The cost: a fraction of what two separate native apps would require to build and sustain.
SvelteKit 5’s Runes syntax — the framework’s newest reactivity model — gave us fine-grained reactive state without the overhead of a virtual DOM. The admin portal and teacher PWA share the same tech foundation but run as completely separate applications. Better Auth manages authentication across both, using a pwa_ table prefix to isolate teacher sessions from admin sessions — no risk of collision between the two user pools.
