Custom Mobile App Development Company

As a custom mobile app development company, NXTMT builds for the way an app actually gets used: one-handed, in bad light, on a three-year-old phone with two bars. Our native app development services and cross platform app development both start with an honest recommendation — a crew app with camera, GPS and offline sync usually wants native; a companion app to a web product is often better served cross-platform, shipping to both stores from one codebase for a fraction of the cost. Either way we handle the parts founders underestimate: store review, push notifications, versioning against your API, and the update path when someone's still on the build from launch week. See our dedicated iOS and Android app development pages for platform-specific detail, or the living-room and voice pages if the target screen isn't a phone at all.

Native, Cross-Platform, or Both?

Mobile apps built for the field, not the demo.

We'll tell you honestly which you need. A crew app with camera, GPS and offline sync usually wants native. A companion app to a web product is often better served cross-platform, shipping to both stores from one codebase for a fraction of the cost.

Either way we handle the parts founders underestimate: store review, push notifications, versioning against your API, and the update path when someone's still on the build from launch week.
