Conversation
You tell me the problem and who has it. I tell you honestly whether an app solves it, and what it would take.
I build Android apps. Six of mine are already on Google Play.
Most app developers can write the code. Far fewer can tell you whether the app should exist, who will actually open it on a Tuesday night, and what will make them come back.
I am an Industrial and Organizational Psychologist who builds software. That means the behavioural question gets answered before the technical one, which is usually the difference between an app that ships and an app that gets used.

What you get
From the idea to the store listing
01
Idea to spec
We start with the problem, not the feature list. If an app is the wrong answer, I will say so before you spend anything.
02
Psychology-led UX
I am an I/O psychologist. Screens are designed around how people actually behave under time pressure, not how a designer imagines they behave.
03
Flutter development
One codebase, native performance, offline-first where it matters. Clean architecture you or another developer can pick up later.
04
Real design system
Typography, colour and spacing with rules, so the app looks considered rather than assembled from a template.
05
Play Store compliance
Data safety declarations, privacy policy, target-audience settings, signing keys and developer verification. The paperwork that gets apps rejected.
06
Launch and listing
Store screenshots, description, keywords and release notes written to convert, not to fill a field.
Proof
Apps I have shipped myself
Not client work described in vague terms. These are live on Google Play under my own developer account, which means I have been through every part of the process that goes wrong: signing keys, data safety declarations, target audience rules, policy rejections, store listings and updates.

How it works
Five stages, each one visible
You get a test build at each milestone, not a surprise at the end.
Spec and design
Screen flow, design system and a clickable direction you approve before a line of code is written.
Build
Built in Flutter, in stages you can see. You get a test APK at each milestone, not a surprise at the end.
Store launch
Signing, Play Console setup, data safety, screenshots, listing copy, and submission.
After launch
Updates, review responses, and the fixes that only real users find.
FAQ
Questions people ask first
Cost, time, the Play Store, code ownership and iOS.
How much does an Android app cost?
It depends entirely on scope, and anyone who quotes before understanding the scope is guessing. A focused single-purpose app is a very different project from one with accounts, payments and a backend. Tell me what the app has to do and I will give you a real number and a real timeline, free of charge.
How long does it take?
A well-scoped first version is typically a few weeks, not months, because I build in stages you can see. You get a working test build early and often, so nothing is a surprise at the end.
Do you handle the Google Play submission?
Yes, all of it. Signing keys, data safety form, privacy policy page, target audience, content rating, screenshots, description and release notes. Most first-time rejections come from that paperwork rather than from the app itself.
Will I own the code?
Yes. You get the full source and the signing keys. Losing a signing key means never being able to update your own app, so I hand it over properly and show you how to back it up.
Can you also do iOS?
The apps are built in Flutter, which means one codebase can produce both. I currently ship Android, and an iOS build is possible as a separate stage with its own App Store process.
What if my idea is not worth building?
Then I will tell you in the first conversation, and it costs you nothing. I would rather lose a project than take money for an app nobody opens.
Everything on this site can be checked before you pay for anything. A free tool runs fourteen measurable checks on any public page in about thirty seconds, and 47 full brand psychology audits are published here in full, no email required.
Have an idea? Let's talk about it.
Tell me the problem, who has it, and what they do about it today. That is enough for me to tell you whether an app is the right answer, what it would take, and what it would cost.
