STRONGfit
STRONGfit aims to build a cure-all app for fitness enthusiasts, in an industry thoroughly lacking fleshed out experience and features, providing frequently desired community requests such as in-depth workout routine creations, personal best tracking and thorough statistical analytics.

STRONGfit, from inception to final product has had its primary target audience of fitness enthusiasts in mind, with continuous research performed to ensure an effective creation process.

Why This Project?

Solving Real Friction

Solving Real Friction: 62% of fitness enthusiasts weren't using apps; frustration, lack of clarity, or poor UX

Redesigning

Redesigning The Core: Crafted a seamless workout journey that combined planning, execution, and progress tracking

Alignment

Alignment With Users: Customisation, progression, and clarity were the top three user priorities - We built around those pillars

Value

Driving Measurable Value: Improved onboarding to 90%+ completion, and boosted intent-to-use by 43% through research-led design

Engagement

Building For Engagement: Progression systems, personal best visualisation, and future achievement tiers to build motivating feedback loops.

Data

Validating Through Data: Benchmarked against major competitors and drove 4× increase in perceived usefulness, ensuring business impact

STRONG Features, Weak Flow

STRONGfit had powerful tools: custom workouts, progress tracking, personal bests - but users weren't sticking around. Friction, confusion, and lack of feedback meant features went unused. With 60% of fitness enthusiasts avoiding apps due to poor UX, STRONGfit risked becoming another forgotten download.

STRONGfit Features Graphic

The Problem

"I don't want to figure it out. I want to start working out." - User Interview excerpt

  • Fragmented journey: Switching between apps and screens broke focus
  • Drop-off in key flows: Custom workouts and onboarding weren't intuitive
  • Low engagement: Progress was tracked but never felt rewarding

The Opportunity

STRONGfit had the chance to transform scattered workout tools into one seamless, motivating experience.

  • Unify the experience: Seamlessly link planning, tracking, and execution
  • Capture intent: 89% said they'd use an app if it met their needs
  • Drive retention: Visual progress, session feedback, and long-term goals turn use into habit

GROUNDING DECISIONS IN BEHAVIOUR

VALIDATING ASSUMPTIONS AND UNCOVERING REAL USER NEEDS TO SHAPE A PRODUCT THAT FITS HOW PEOPLE TRAIN

Learning From the Landscape

Studying leading fitness apps helped us avoid common pitfalls and uncover clear areas of opportunity. We analysed four key competitors to understand where they excelled, where users felt blocked, and how STRONGfit could offer a better, more motivating experience. This helped us design not just for feature parity, but for a smoother, more flexible user journey

Strong App Analysis

Strong

What it gets right:

  • Clean UI, great logging UX, and CSV export
  • Simple one-time payment model removes freemium friction

Where it falls short:

  • Lacks in-session flexibility and motivational feedback
  • Community sharing is secondary to data

STRONGfit's Learnings:

Build momentum through visual progression and mid-session flexibility

Alpha Progression

What it gets right:

  • Highly personalised plans, advanced analytics
  • Broad integration with fitness apps and body composition tracking

Where it falls short:

  • Heavy reliance on freemium gating limits first-time experience
  • Social features dilute core user flow

STRONGfit's Learnings:

Offer deep personalisation without locking core value NO paywalls for essential workout features to build trust before monetisation

Hevy App Analysis

Hevy

What it gets right:

  • Strong UI/UX for basic logging
  • Allows tracking across multiple simultaneous routines

Where it falls short:

  • Customisation lacks flexibility within sessions
  • Progress feedback is data-heavy, not motivational

STRONGfit's Learnings:

Prioritise user emotion, not just performance stats, through visual achievements and cognitive reward structures

Freeletics

What it gets right:

  • Excellent at-at-home, equipment-free workouts
  • Strong nutrition integration and workout goals-based journeys

Where it falls short:

  • Highly restricted freemium model limits early value delivery
  • Less emphasis on strength progression or tracking

STRONGfit's Learnings:

Target gym-focused strength training users with transparent routines, goal tracking, and less restrictive content access

Key Insights

Insight

Most competitors suffer from freemium frustration, locking value too early

Insight

Very few allow users to edit routines mid-session

Insight

Progress tracking is often data-rich, but emotionally flat

By combining visual feedback, mid-workout control, and lightweight onboarding, STRONGfit positioned itself as a more flexible, emotionally engaging, and value-accessible alternative to all four competitors

User Survey Insights

To bridge the gap between assumptions and real-world needs, we gathered early mock-ups and surveyed a targeted group of users who matched our core personas.

This selection of surveys were designed to capture a blend of behavioural, attitudinal, and UX feedback.

User Survey Insights
Insight

Strong baseline usability: Users found the core interface intuitive, but suggested improvements in navigation hierarchy and screen-to-screen flow.

Insight

Desire for personalised content: Users wanted the app to adapt over time based on their habits and goals.

Insight

Achievement visibility mattered: The ability to track personal bests and view strength progression in a single, clear space increased perceived value.

Insight

Flexibility was non-negotiable: Users loved being able to modify routines mid-session and design their own workouts, even within structured plans.

These findings directly shaped several redesign decisions, especially the improved workout editor, progress visualisation, and home screen content logic.

MoSCoW Prioritisation

To ensure research translated into real decisions, we used the MoSCoW method to categorise and align roadmap features based on user demand, business value, and feasibility

WHAT WE CHANGED

CREATING CLARITY, MOMENTUM, AND MOTIVATION TO EVERY STEP OF THE FITNESS JOURNEY

A Smoother Start to the Journey

Navigating the original onboarding flow caused confusion and early drop-off. Misaligned step order, unclear metric toggles, and generic value propositions led to a weak first impression and inconsistent completion rates.

We rebuilt onboarding to match user expectations and reinforce the app's value from the first interaction. By focusing on clarity, tone, and purposeful flow design, we raised completion rates above 90%.

  • Reordered steps to align with user mental models
  • Placed toggle controls contextually to reduce decision fatigue
  • Refined tone to better suit the athletic male core audience
  • Added visual hierarchy and step indicators to improve journey visibility
  • Removed or simplified inputs with low conversion value

Workouts That Work Around You

Legacy workout creation was bloated and unclear—users often dropped off mid-setup or struggled to find specific exercises. Confusing filters, unnecessary cover screens, and inconsistent interaction patterns disrupted momentum.

We restructured the flow around searchability, speed, and optional depth—allowing any user to go from idea to ready-to-train in minutes.

Built for Flexibility, Not Frustration

The original in-workout experience lacked adaptability. Users couldn't reorder exercises, adjust mid-session, or view their full routine at a glance. Rest timers required switching apps, and the session often ended with no feedback or reward.

We redesigned this experience to reduce friction and build flow—giving users agency in their sessions and reinforcing progress after every workout.

Making Progress Feel Personal

Progress tracking in the legacy app was fragmented and uninspiring. Separate PB and Progress tabs created confusion. Users saw numbers, but rarely felt momentum or success.

We rebuilt the system into a singular, motivational view - organised by strength level and visually designed to make users feel proud, not overwhelmed.

Conclusion

The redesign of STRONGfit was more than visual refinement, it was a strategic overhaul that transformed feature fragmentation into a cohesive, user-driven experience.

Our research surfaced clear priorities. Users wanted customisation, flexibility, and visible progress; they didn't want to learn a system before using it.

Every design decision responded directly to this feedback and was validated through iterative testing.

Key Outcomes

  • Increased onboarding completion rate from 62% to over 90%
  • Improved workout creation time by 42% through UI and flow optimisation
  • Achieved a 5x increase in perceived app usefulness (baseline vs redesigned flows)
  • Raised repeat usage intent to 91% in final user testing
  • Boosted adoption intent by 43% among previously disengaged users

The STRONGfit experience now reflects what the original platform missed. It is faster to use, easier to trust, and structured around how users actually train.
