Cognify is a mobile product studio. We design, build and publish our own apps on the App Store and Google Play — and bring that same team to yours. Fixed scope, a build on your phone every fortnight, and care long after launch.
Our apps
The best proof a studio can offer is software you can download today. These are ours — designed, engineered and published by the same team that builds for clients.
Utilities
Phone-to-phone transfer. No cable, no cloud.
Nimbo moves photos, videos, files, contacts and apps straight from one phone to the one beside it over a direct Wi-Fi link. No account, no internet, and nothing ever touches a server.
Productivity
Cloud storage that starts without a sign-up.
Vault gives everyday files a place in the cloud. Start with 5 GB free and no account, upload photos, videos and documents, and keep them organised in folders you control.
Health & Fitness
Your health, finally explained.
Symptra is an AI health companion for the questions between appointments: a symptom at 11 p.m., a side effect you are unsure about, lab results that arrived with no explanation.
The stack we build on
Why projects stall
They fail at three predictable points. Our process exists because of them, not in spite of them.
Every feature sounds essential in a kickoff meeting. Six months later the budget is spent on things no user asked for and the app still is not live. We cut v1 down to what proves the idea, and we put the rest in writing for later.
Account deletion, subscription disclosure, permission strings, sign-in walls, data safety forms. Almost every rejection traces back to a decision made during design. We audit against both guideline sets before we submit, not after.
iOS and Android ship breaking changes every year. Without someone watching, a working app becomes a crashing app, then a delisted one. Care is a service we sell, not a favour we forget.
What we do
Six disciplines, one team. You are not stitching together a designer, an agency and a freelancer who stopped replying.
Before a line of code: what to build, what to cut, and what it will cost. You leave discovery with a scoped backlog and a fixed launch date — not an estimate range.
What you get02Interfaces built on Material 3 and Apple Human Interface Guidelines, so the app feels native on each platform instead of a web page in a shell.
What you get03Swift and Kotlin when the app lives or dies on performance. Flutter or React Native when one codebase on two stores is the right trade. We will tell you which you actually need.
What you get04The part users never see and never forgive. Authentication, data, payments, notifications and realtime — sized to your actual load, not a conference demo.
What you get05Review rejection is the most common cause of a missed launch date, and almost all of it is preventable. We handle submission end to end.
What you get06Version 1 is where the work starts. OS releases, SDK deprecations, crash regressions and review replies do not pause because the project ended.
What you getHow we work
You always know which phase you are in, what comes out of it, and when. Here is the whole thing.
Discovery
Most failed app projects were scoped as v3. We pull your idea apart, map the flows, cut everything that will not change a launch decision, and write it down as a fixed scope.
Design
Screens and a tappable prototype. Changing a flow in design costs an afternoon; changing it after the backend is built costs a sprint. You sign off on something you have held in your hand.
Build
You get a build on your device every two weeks, a written release note, and access to the board and repository the whole time. No demo-day surprises.
Hardening
Real devices, bad networks, low storage, denied permissions, interrupted payments. Plus a full pass against both stores’ review guidelines before we ever hit submit.
Launch
Listings, assets, privacy declarations and submission on both stores. If a reviewer pushes back we write the response — that is our job, not yours.
Care
iOS and Android ship breaking changes every year. We handle upgrades, watch crash rates against an agreed threshold, and plan the next release with you.
Non-negotiables
These are not upsells or a premium tier. They are the floor — the things that decide whether an app is still healthy a year after launch.
No lock-in, by design. The code, the accounts and the credentials are yours throughout. If you want to move the work in-house or elsewhere, we will help you do it.
Code lives in your GitHub or GitLab organisation from the first day, not ours. You can clone it, read it and take it elsewhere at any point.
TestFlight for iOS, internal testing track for Android, every two weeks. Progress you can tap, not a status percentage in a spreadsheet.
Type checks, linting, unit and widget tests, and a signed build run on every pull request. Nothing reaches main on trust alone.
We agree a crash-free session threshold before launch and monitor against it. If a release drops below it, fixing that outranks new features.
VoiceOver and TalkBack labels, contrast ratios, dynamic type and 44pt touch targets are acceptance criteria on every screen we build.
Architecture notes, environment setup, credentials inventory, runbook and a walkthrough call. Another team could pick this up without calling us.
Straight answers
A focused v1 on both platforms typically lands between a small, single-purpose utility and a full marketplace with payments and realtime features — the range is wide because the scope is. That is exactly why we start with a paid product sprint: you get a fixed number against a written scope instead of an estimate that moves. If the sprint tells you the idea is not worth building, that is a good outcome and a cheap one.
It depends on what the app does. Heavy camera, audio, Bluetooth, background processing or platform-specific UI: native Swift and Kotlin. Content, commerce, booking, social and dashboard apps where the two platforms should behave identically: Flutter or React Native, one codebase, roughly 60–70% of the cost of two native builds. We make the recommendation in discovery, in writing, with the trade-offs stated.
For a well-scoped v1: 3–5 months from kickoff to a live listing, including store review. Discovery is 1–2 weeks, design 2–4, build 6–14, hardening 1–2, then submission. Apple review is typically 24–48 hours once you submit something that passes the guidelines — the delay people remember is usually a rejection loop, which is what our pre-submission audit exists to prevent.
You do, entirely. The repository sits in your organisation from the first commit. The App Store Connect and Google Play accounts are registered to your company, with us added as users you can remove. Every credential, key and certificate is inventoried and handed to you. There is no lock-in mechanism in our contracts because we do not want clients who stay for that reason.
We handle it — writing the response, making the change, resubmitting. It is included, not billed as extra. We also audit against both guideline sets before submitting, which is why it rarely gets that far. The rejections that do happen are usually about account deletion, subscription disclosure, permission usage strings or login requirements, and all of those are decided during design, not at submission.
