App Design & Development
Apps taken all the way to the store.
Writing the app is roughly half the job. Signing, store policy, subscription plumbing, release packaging, and the review rejection nobody warned you about are the other half — and they're where most first-time app projects stall.
Why us
We run this gauntlet for our own products.
R&T BrightLight builds and maintains its own applications alongside client work. Every store policy, signing certificate, and subscription edge case we would hit on your project, we have already hit on ours.
That means the estimate you get accounts for the unglamorous half of an app project — the parts that are invisible in a design mockup and expensive in a schedule.
Platforms
One codebase, every screen your customers use.
We build cross-platform with .NET MAUI, so Android, iOS, and Windows come from a single, maintainable codebase rather than three separate projects drifting apart.
Mobile
Android and iOS, published under your own developer accounts so the listing, reviews, and revenue belong to you from day one.
Desktop
Windows applications from the same codebase — useful when field staff use tablets and back-office staff use desktops with the same data.
The backend behind it
APIs, authentication, sync, and cloud infrastructure — designed together with the app rather than bolted on once the screens are done.
The path to launch
From idea to a live listing.
Every stage below is scoped and quoted up front, including the ones most proposals quietly leave out.
-
Define & design
What the app must do, for whom, and what it must never do. Screens and flows agreed before code, so changes happen in a design tool rather than a sprint.
-
Build
Layered architecture, automated tests, and a build pipeline from the first commit. You see running builds on real devices throughout, not at the end.
-
Store readiness
Signing, packaging, permissions, privacy declarations, data-safety disclosures, listing copy, and screenshots — prepared to each store's current requirements.
-
Monetization
Store-managed subscriptions, in-app purchases, or advertising, integrated and tested against the sandbox before a single real customer touches it.
-
Release & iterate
Staged rollout, crash and adoption monitoring, and a repeatable update pipeline so version two isn't a second project.
Included, not extra
The unglamorous parts, handled.
Signed release packaging
Certificates, keystores, and automated signed builds — documented so you're never one lost credential away from being unable to ship.
Store compliance
Privacy policies, data-safety forms, permission justifications, and age ratings prepared correctly the first time.
Subscriptions & ads
Google Play and App Store billing integrated and tested, including restore, upgrade, cancellation, and grace-period behavior.
Offline behavior
What your app does with no signal, designed deliberately — including on-device AI where it makes the product better.
