Launch your first mobile app
in a matter of weeks
We take you from an idea to your logo in the App Store and Google Play. From UI/UX design to full development and launch, all under one single roof.
What we can do for you
From native iOS and Android App design and development, to crafting responsive web experiences, we support your needs by utilising a single code base in Flutter & FlutterFlow.
Our in-house UX experts engineer flows and screens optimized for long in-app usage, high retention, and low churn rates. They design apps that are intuitive to navigate and empower users instead of confusing them.
Our UI design team creates a unique identity for your app. One that stands out, builds brand recognition, and makes users feel at home while resonating with their values and personality.
Alongside our excellent frontend team we have Supabase-certified backend specialists who ensure your product is secure, reliable, and able to support millions of users.
Our team is Stripe and RevenueCat certified, ensuring your app supports secure payments. We enable smooth one-time charges and subscriptions with full visibility into in-app purchases and customer payment profiles.
We manage the project so you don’t have to. Our experienced project managers act as your single point of contact, keeping everything on track from start to finish. You receive weekly progress updates and can reach us anytime through Slack for quick answers to your questions
Before launch our quality assurance specialists run extensive tests to ensure every button, feature, and flow works properly. This guarantees that once your product goes live, users experience it exactly as you envisioned.
Once QA is complete we also publish the app for you. After launch we provide ongoing support so you never feel alone. Whether it is post-launch maintenance, new features, or a simple technical question, you can always count on us. Once a Calda client, always a Calda client.
