App Development
Mobile and web apps that people keep using.
Preview copy. Case studies for this service are coming soon.
App development is the design and build of mobile and web apps that people keep using. Altangle builds iOS, Android and installable web apps for the field, not just the demo, with offline-first data, secure sign-in, maps and notifications, and AR or 3D content when the product calls for it.
Overview
How we approach it
We build apps for places where the signal drops and people are in a hurry: temple circuits, clinics, survey sites. That means offline data, fast start-up and interfaces that work one-handed.
Every app ships with secure authentication, push or WhatsApp notifications where useful and a release process we run for you through the app stores.
