Fit
Is this right for you?
Usually the right call when one of these sounds familiar.
Customers expect an app
A website alone no longer meets how they want to reach you.
Staff work away from a desk
They need tools that work on a phone, sometimes without signal.
One platform covered, not both
You have an iPhone app and Android users are waiting.
An app that feels slow or dated
Updates are difficult and reviews keep mentioning it.
Not the right service? A service that runs in the browser: Web apps. Only the screens, not the build: UI design.
Scope
Scope and what you get
Each piece of work has a matching thing you receive.
- What we do
Platform choice
We compare one shared codebase with separate native apps and recommend one, with reasons.
What you receiveA written recommendation
The approach, the trade-offs and why it suits your product.
- What we do
Build for both platforms
Screens, navigation and logic are built and tested on real iOS and Android devices.
What you receiveWorking apps on both platforms
Builds you can install and try as the work progresses.
- What we do
Notifications and offline use
Push messages and sensible behaviour when the connection drops.
What you receiveBehaviour people can rely on
Clear rules for what works offline and how data syncs when the connection returns.
- What we do
Store submission
We prepare listings, assets and builds for App Store and Google Play review.
What you receiveReady for review
Submission materials and guidance, with the store accounts held by you.

Sample use cases, drafted as placeholders. The Plethora team confirms the final list.
Process
How it works
Each stage is agreed with you as we go. Each shows what we do and what we need from you.
Understand
We doWe learn who uses the app, on which devices, and what must work without a connection.
You doYou describe your users and share any existing designs or back end.
Plan
We doWe choose the build approach and agree the first release and its screens.
You doYou confirm the scope and name who approves each release.
Build
We doWe build in short releases and test on real devices, sharing builds as we go.
You doYou install the builds, try them and tell us what to change.
Release
We doWe prepare the store submission and hand over the code and notes.
You doYou hold the store accounts, approve the listing and decide on support.
Quality
Quality and handover
How the work is checked, accepted and passed to you.
Tested on real devices
Builds are tried on a range of phones and system versions, not only in simulators.
Reviewed before release
Every change is checked by a second engineer before it joins a build.
Your store accounts
Developer accounts and signing keys belong to you from the start.
A defined handover
Code, build steps and release notes pass to your team with a walk-through.
Tools
Tools and technology
Tools we use in delivery. We choose them to suit your team, and the list does not imply any partnership. Logos belong to their owners.

What shapes scope, timing and cost
- Which platforms and device types are involved
- Whether one shared codebase or native code fits
- Offline, notification and device features needed
- The back end the app connects to
- Store requirements and review time
- How much support you want after launch
Scope and cost are confirmed with you in writing before work starts.
