Don’t just look — use it

This is a real application, running right here.

Not a screenshot, not a video. Click into it, search, submit a form, switch roles, trigger an error. Every demo runs on realistic sample data and nothing is connected to a production system.

The trainer’s pocket CFO — use it right here.

Try this
  • Open the “$500 at risk” card and recover a failed payment
  • Search the client list, then log a session with an invalid amount to see validation
  • Switch to the accountant role and try the same action
How this works

See it. Test it. Specify it. Build it.

01

See it

Open any application in the demo library and watch it work.

02

Test it

Use it yourself — click, type, filter, submit, switch roles.

03

Specify it

Pick the capabilities you need and generate an app blueprint.

04

Build it

Send the blueprint. We reply with what we’d build and in what order.

The work

Every app here opens a demo you can use.

Each one has its own interface, its own data and its own workflows — because the range is the point. Open one and spend two minutes inside it.

How we work

Concept to App Store in 4–8 weeks.

A clear, corporate-friendly process built for trust: fixed scope, weekly demos, and a beta you can test.

01

Discover

A short call and a fixed scope. We understand the business, users, and goals — then quote a flat price.

02

Design

A clickable prototype in week one — you see and feel the UI before a line of production code.

03

Build

Weekly builds you can actually run, plus the backend and integrations your app needs.

04

Test

QA, real-device testing, and a TestFlight / Play beta so you test the real app yourself.

05

Launch

App Store & Google Play submission, review rejections handled — it’s not done until it’s live.

Why corporates trust us

Built for companies that can’t afford to get it wrong.

Clear ownership, fixed pricing, and a process designed so you always know exactly what you’re getting.

You own everything

Source code, App Store listing and IP are yours. We can build in your own developer account.

NDA-friendly

Happy to sign an NDA before we talk specifics. Your idea stays yours.

Fixed scope & price

A written scope and a flat quote up front — no open-ended hourly surprises.

You test the real app

A TestFlight / Play beta every week means you’re never guessing what you’re getting.

Approval handled

We know Apple’s and Google’s review rules and fix rejections — it’s not done until it’s live.

Privacy & security first

Secure auth, encrypted data, and privacy-compliant handling built in from day one.

What does an app cost to get onto the stores?
Two developer accounts, and they’re yours: an Apple Developer account is $99/year, and a Google Play developer account is a one-time $25. We handle the setup and submission — you keep the accounts and full ownership.
How long does it take?
Most apps go from idea to App Store in 4–8 weeks, depending on scope. You’ll see a clickable prototype in week one and a working build every week after.
Do I own the code and the app?
Completely. Source code, the store listings, and all IP are yours. We can build directly in your own Apple and Google developer accounts.
What if Apple rejects the app?
We know the review guidelines and handle rejections as part of the job. It’s not finished until it’s live on the store.
