Mobile App Design That Drives Downloads, Activation, and Retention
Onboarding, activation and retention designed for the phone, with the App Store assets the launch needs.
Trusted by funded B2B SaaS teams






Case Studies
A few of the products we've shaped.
PROJECTS
Install to habit
We follow a mobile-specific design process optimized for activation and retention.

Discovery & User Mapping
We start with your users, your business model and the metric you are judged on. What counts as activation here, and what brings someone back on day seven. Out of that comes a map of the journey from the store listing to a habit, with the moments marked where design decides whether it holds.
Typical outputs:
Who installs and why
The metric we are moving
Platform constraints, iOS and Android
What the first session must achieve
What you get
The design work that decides whether an install becomes a habit: the first session, the paywall and everything after.

The first session
The path from opening the app to the moment it is worth keeping.
Where most apps lose the user.

Platform-native screens
Designed for each platform's conventions rather than one layout stretched across both.
Your reviewers notice.

Activation and paywalls
Upgrade moments designed against the metric rather than dropped in at the end.
Tested before the build.

Retention design
The second week designed as deliberately as the first session.
Retention is a design problem.

A component set
So the next screen your team adds looks like the app.
In your stack.

Store assets and handoff
Everything the launch needs, plus files your engineers build from.

Industries We Work With
B2B SaaS first, with most of our work in fintech, healthtech and AI products.
Fintech
AI finance, fintech SaaS and B2B financial tools. Trust, density and compliance in the same screen.
Healthtech
Healthtech SaaS and compliance platforms, designed under HIPAA and OSHA constraints.
SaaS
B2B products moving upmarket, with design debt to pay down before the next release.
AI & ML
AI features that have to survive an enterprise demo: uncertainty, corrections, audit trail, failure states.
Why teams design the app with us
Downloads are cheap and retention is not. The work is scoped around the first session and the second week.
- Activation-obsessed
- We measure success by activation rate, not screens delivered. Every design decision is evaluated: does this help users reach value faster? Does this reduce friction in the critical first session?
- Retention mechanics expertise
- Streaks, rewards, notifications and social proof each work in some products and corrode trust in others. We know which is which, and we design the version people keep rather than the version that spikes for a month.
- Paywall conversion specialists
- Monetisation UX is its own discipline. We have designed paywalls around timing, value shown before the ask, and the way people actually decide on a subscription.
- Platform-native quality
- Apps we design feel like they belong on the platform they run on, with native patterns and animation that matches the system. A web app in a mobile shell reads as one within seconds.
- Full journey thinking
- The journey runs from the store screenshot to a habit, and we design all of it: store presence, first open, onboarding, activation, the second week, and the upgrade moment.
- Startup speed, premium quality
- MVPs in 4-6 weeks without cutting corners. We know how to ship fast while maintaining the quality bar that mobile users expect from top apps.
