Customer apps
Sign-up, profiles, notifications and the core journey your customers came for, with analytics to see what they use.
What we build Mobile apps
iOS and Android apps, built once and published to both stores.
One React Native codebase serves iPhone and Android, so you pay for one team and ship to both stores together. We plan for weak signal, sync conflicts and store review from the start, not the week before launch.
What we build
Field and staff apps
Apps that keep working offline and sync safely when the signal returns, so nobody loses a morning of work.
Companion apps for a web product
A mobile app that shares the same APIs and accounts as your web app, so data stays in one place.
Store release and updates
App Store and Google Play submission, test builds for your team, and over-the-air fixes where the stores allow them.
Questions buyers ask
Native or cross-platform?
For most business apps one React Native codebase is faster and cheaper, and users cannot tell the difference. If your app needs heavy native features, we say so on the first call.
Do you publish the app to the stores?
Yes. We prepare the listings, handle review feedback and publish under your developer accounts, so the app always belongs to you.
Can the app work without a connection?
Yes. We decide with you which data lives on the phone, how edits queue while offline, and what happens when two people change the same record.
How a project runs
From the first call to a working release, with a clear next step at every stage.

Tell us about your goals, users, current systems and constraints. We suggest a sensible first step, with no obligation.
Scope and estimate
We agree on a focused first release, with priorities, milestones and an estimate you can plan around.
Build with regular demos
You see working software early and often, so decisions stay grounded in what you can use.
First release in 4–8 weeks
A focused first release typically ships within that window. Larger systems such as ERP platforms ship in phases, followed by ongoing support.

Field notes from our engineers that apply to mobile apps.
All field notes
Consumer & wellness apps
Offline-first app architecture: backups that merge, deletes that stick, DST-safe streaks
Users switch phones, restore old backups and log at 1 a.m. on DST weekends. Here is the offline-first design we built for each moment, and where it still falls short.
Healthcare & pharmacy
E-prescription software development: printouts pharmacists can verify by QR scan
Pharmacists can’t tell a genuine prescription from an edited one. Here is how we built prescriptions they verify with a QR scan that holds no patient data and opens a deliberately minimal page.
