The Design Sprint
A proven 6-week framework that takes your idea from whiteboard to the App Store — no surprises, no scope creep.
Week 1
Discovery & Wireframes
Stakeholder workshops, user journey mapping, and low-fidelity wireframes to lock in scope before a single line of code is written.
Weeks 2 – 3
Design & Prototype
High-fidelity Figma screens, branded design system, and a clickable prototype for stakeholder sign-off before we build.
Weeks 4 – 5
Development Sprint
Agile sprints with daily builds. You get a TestFlight or Google Play internal track link to review progress in real time.
Week 6
Testing & Launch
QA across 15+ real devices, App Store & Google Play submission, ASO metadata optimisation, and go-live support.
Built With Industry-Leading Tools
We choose the right technology for your product — not the trendiest one.
Backend Infrastructure & Services
Every app we build ships with a production-grade backend — secure, scalable, and fully observable from day one.
Authentication & Auth0
Passwordless, social login, MFA, and enterprise SSO via Auth0. JWT sessions, refresh token rotation, and RBAC out of the box.
Real-Time with WebSockets
Live chat, collaborative features, and live dashboards powered by Socket.io or AWS API Gateway WebSocket APIs.
Payment Processing (Stripe)
One-off payments, subscriptions, in-app purchases, and marketplace splits. PCI-DSS compliant, webhook-verified.
Push Notifications
Segmented campaigns via FCM & APNS. Rich media pushes, A/B title testing, delivery analytics, and scheduled triggers.
Analytics Dashboard
Custom event tracking, funnel analysis, crash reporting (Sentry), and live KPI dashboards — all in one place.
Cloud Storage (AWS S3)
CDN-backed media delivery, presigned upload URLs, lifecycle rules, and server-side encryption for every file.

Transparent, fixed-fee packages — choose the scope that fits your stage.

What Our Clients Say
Real feedback from founders and teams who shipped with SixVM App Studio.
"SixVM delivered our entire React Native app in exactly 6 weeks. TestFlight builds were dropping daily — the team's communication was flawless. We launched on time with zero critical bugs."
"The Stripe integration and the admin dashboard they built saved us days of manual work every single month. Our app hit 4.9 stars on the App Store within the first three months."
"As a non-technical founder I was nervous. SixVM walked me through every decision, gave me Figma prototypes before writing code, and the final product exceeded every expectation."
