We build mobile apps the way a machinist builds a part.
No loose fittings, no guesswork. NutsNTech designs, engineers, and ships native and cross-platform apps for teams who need them to hold up under real usage — from first install to the App Store review queue.
What we build
Four disciplines, one shop. We take on the whole build or bolt onto a team that already has parts moving.
Swift and Kotlin builds for apps where platform feel matters — smooth animations, correct gesture behavior, and full use of what each OS actually offers.
React Native or Flutter where one codebase genuinely saves you money without costing you feel. Shipped to both stores, not just a prototype build.
The server side built to match how mobile actually behaves — offline sync, push infrastructure, and APIs that handle a spotty connection gracefully.
Store listing prep, review-guideline compliance, crash monitoring, and the release pipeline set up so your team can ship updates without us in the loop.
How a build goes together
Same four stages on every app, whether it's a two-week fix or a year-long build heading for both stores.
Spec
We sit with your team, map the real requirements, and write a spec you can hold us to — not a slide deck.
Prototype
A working build on a real device ships within the first sprint, so we're arguing about the real thing, not a mockup.
Build
Two-week cycles, a demo at the end of every one, and a changelog you actually get to read.
Torque check
Device-lab testing, store-review compliance, and a handover doc thorough enough that your team can ship updates without us.
Recent builds
A few of the apps currently live in the App Store and Play Store.
Fleetmark
Driver-facing native app with offline-first routing for a regional delivery fleet of 300+ vehicles, syncing the moment signal returns.
Ledgerhouse
Cross-platform companion app for a reconciliation platform, letting finance teams approve transactions from a phone instead of waiting for a desk.
Clinic Relay
HIPAA-compliant patient app for appointment booking and secure messaging, built to pass App Store health-data review on the first submission.
Shelfline
Staff-facing inventory scanner app unifying 14 store locations onto one real-time stock ledger, running on handheld Android scanners.
NutsNTech is a small mobile app studio that builds like tolerances matter — because on a phone, they do.
We started as three engineers tired of watching apps ship with the wrong platform feel and a launch date that slipped past the store review queue. So we built a shop that specializes in exactly one thing: mobile.
Every build gets the same treatment regardless of size: a real spec, a working build on a real device early, and a torque check before we submit to either store.
Real devices, always
We test on physical phones and tablets throughout the build, not just a simulator that never drops signal.
Store-ready, not store-hopeful
We know the App Store and Play Store guidelines cold, so submission isn't where the timeline goes sideways.
Built to be maintained
We write code assuming someone else reads it in two years, because someone usually does.
Small team, direct line
You talk to the engineers building your app, not an account manager relaying notes.
