Is this right for me?

The signs your app needs intervention

These are the patterns we see in wellness apps that were built once but never properly evolved. If two or more apply, a Growth & Rebuild will have material impact.

Retention is dropping

Users download the app but disappear within a week. Day-7 retention is below 20% and getting worse. The onboarding flow isn't converting.

Ratings are slipping

Your App Store rating has drifted below 4.0. Reviews mention bugs, confusing navigation, or missing features. New users see the reviews and bounce.

Subscribers aren't converting

Free users don't upgrade. Your paywall isn't positioned at the right moment, the value proposition isn't clear, or the free tier gives away too much.

The design feels dated

Competitors have raised the bar. Your app looks like it was built three years ago (because it was). The brand experience doesn't match your other touchpoints.

Technical debt is piling up

Every new feature takes twice as long as it should. Your previous developer left, or the codebase has become unmanageable. You're afraid to touch it.

You don't know what to fix first

There are 50 things wrong and you're not sure which ones matter. You need someone who's seen this before to tell you where to focus.

What we do

Targeted fixes rather than a total teardown

You’ll know exactly which 20% of changes drive 80% of the improvement. Every engagement starts with an audit and ends with measurable progress.

Product & UX Audit

A comprehensive review of your app's user experience, technical health, analytics, and App Store reviews. We identify exactly what's broken and prioritise by impact.

User Research & Churn Analysis

Interviews with existing users, analysis of drop-off points, and churn pattern identification. We find out why people leave.

Improvement Roadmap

A prioritised, phased plan of targeted fixes. Scored by effort vs. impact so you know exactly what to tackle first and what the expected outcomes are.

High-Impact Flow Redesign

Redesign and rebuild of the flows that matter most — typically onboarding, paywall, core habit loop, and notification strategy. New UX, new code, shipped.

AI Feature Integration

Personalised recommendations, adaptive content, intelligent coaching prompts, or AI-powered journaling. Features that modernise the experience and boost engagement.

A/B Testing Framework

Set up proper experimentation infrastructure so you can continue optimising after we're done. No more guessing, measure what works.

How it works

Three phases, clear milestones

Unlike an open-ended retainer, every Growth & Rebuild has a defined scope, timeline, and set of measurable outcomes.

Phase 1

Audit & Research

2–4 weeks

Deep dive into analytics, user interviews, competitor benchmarking, technical assessment, and App Store review analysis. We identify the critical issues and rank them by ROI.

Phase 2

Redesign & Build

4–12 weeks

We redesign and rebuild the highest-impact flows. New UX design, user testing, and iterative development. You see working updates every two weeks.

Phase 3

Ship & Measure

2–4 weeks

Push updates to the App Store, set up A/B tests, and monitor key metrics. We stay for 30 days post-release to measure impact and iterate on what we've shipped as needed.

AI-powered growth

Add AI features that actually matter

Users are intrigued by AI-powered features. But most implementations are superficial. We integrate AI as a core part of the experience when necessary.

Personalised Coaching

AI that adapts to the user's progress, preferences, and patterns. Coaching that feels individual, delivered at scale.

Intelligent Journaling

AI-generated prompts that respond to what the user has written. Reflective, supportive, and contextually aware.

Adaptive Content

Workout plans, recipes, or practices that evolve with the user. A genuinely personalised experience.

Smart Notifications

ML-driven notification timing and content. Send the right message at the right moment, reducing opt-outs while increasing engagement.

Proof: Five Minute Journal

From a false start to 4.8 stars and 25k+ reviews

The Five Minute Journal app didn’t start with us. The first version was built by a different developer and wasn’t working. Here’s what happened next.

Before All Shapes

The false start

Intelligent Change hired a developer to build their first app. It launched with poor reviews, limited functionality, and no habit-forming mechanics. The digital product was hurting the brand.

2015 — V2 Rebuild

Complete rebuild

We audited the existing app, identified the critical gaps, and rebuilt from scratch. New UX centred on the five-minute habit loop. Ratings climbed immediately.

2020 — V3 Subscription

Revenue model redesign

Introduced subscription billing, premium content, and deeper personalisation. Unlocked recurring revenue while maintaining the core simplicity that users loved.

Today

4.8 stars, 25k+ reviews, 60k MAU

The app has been featured by Apple multiple times, expanded to Android and web, and become the digital home for Intelligent Change's brand.

How it compares

Rebuild vs. Start Over

A full rebuild from scratch isn’t always the answer. Here’s how the Growth & Rebuild compares to commissioning a new app.

Full New Build

When the codebase is unsalvageable or the product vision has completely changed.

Investment: £80–250k+
Timeline: 4–12 months
Risk: Starting over — losing existing users, data, reviews
App Store continuity: May need new listing, lose reviews
When to choose: Codebase is unsalvageable or the product vision has completely changed

Growth & Rebuild

When the product concept is sound but execution needs improvement.

Investment: £30–80k
Timeline: 2–6 months
Risk: Incremental — keep what works, fix what doesn't
App Store continuity: Same listing, reviews preserved
When to choose: The product concept is sound but execution needs improvement

Common questions

Before you book

"How do you know what to fix without seeing the codebase?"

The audit phase gives us full visibility. We review your analytics, App Store reviews, technical stack, and talk to your users. By the time we start building, we know exactly where the leverage is.
"Can you work with our existing codebase?"

Yes. We've worked with codebases in Swift, React Native, Flutter, and Kotlin. If the code is genuinely unsalvageable, we'll tell you during the audit and recommend a full build instead.
"What happens after the engagement?"

You get the A/B testing framework, an optimisation playbook, and all source code. You can continue with your team, hire internally, or retain us for ongoing development.
"Do you offer AI integration as a standalone service?"

AI work is always paired with a product audit. Bolting AI onto a broken UX makes the UX worse, not better. We need to understand the full picture before recommending where AI adds genuine value.
