Fitness App UI Concept

Last Updated on August 4, 2026 by Editorial Team

A minimalistic design concept of a Fitness Application created and released by Ronan Buckley. The Sketch file contains a style guide (typography, logo, and color) and 9 different mobile screens:

• login
• create identity
• plan a run
• run map
• run route
• calories progress
• calories graph
• calories bar
• calendar (with deadlines)

Happy downloading!

Look at the arrangement of screens and a clear visual logic starts to emerge: white and light-grey surfaces carry most of the interface, while a single red-to-orange gradient is reserved for the moments that matter most, like the “Plan Run” call to action and the pulsing location marker on the map screen.

That kind of restraint is the real lesson here. Instead of spreading color evenly across every screen, the gradient acts as a signal for action and progress, while calmer states like login, create identity, and the calendar stay quiet and neutral.

The calorie tracking screens push this idea further with a navy-and-red wave chart and a bold circular progress ring showing “3500 of 5000 calories.” Both are strong examples of turning raw numbers into something glanceable, which matters a lot in a fitness UI concept where users are often checking stats mid-workout rather than sitting and reading.

The food list screen breaks from the flat UI style with real photography, pineapple, coconut, dragon fruit, shot in warm, saturated tones against soft pastel backgrounds.

It is a nice reminder that even a minimal mobile app design can use texture and photography selectively, as a way to make nutrition content feel more tactile and appetizing than another row of icons and text would.

Where This Concept Works Best

This kit reads as a strong reference point for anyone designing or pitching a running, calorie counting, or general health and wellness app.

The screen set already covers a realistic user journey: onboarding and identity creation, planning and tracking a run, visualizing calorie intake in more than one chart style, and managing goal deadlines on a calendar.

That makes it useful in a few different ways:

• As a mobile app UI kit to study when structuring your own fitness or activity tracker flow
• As a moodboard for how much (or how little) color to use in a health-focused product
• As a starting point for client presentations, mockups, or portfolio case studies about fitness app design
• As inspiration for data visualization patterns, since the calorie graph and progress ring solve the “show progress at a glance” problem cleanly

If you plan to adapt these screens for your own project, start with the color system before touching layout.

Because the gradient is used so sparingly, swapping it for a brand’s own accent color, blue for a swimming app, green for a plant-based nutrition tracker, is usually enough to make the whole concept feel native to a new product without redrawing components.

From there, the typography and spacing in the style guide give you a consistent baseline, so headings like “Create Identity” or “Calorie Stats” can be relabeled for different features while keeping the same rhythm of whitespace and alignment.

When editing the chart-heavy screens, keep the same trick the original uses: let one or two colors carry the data, and leave everything else, backgrounds, icons, secondary text, in neutral greys so the numbers stay the focus.

Pair these screens with a simple icon set for navigation and stat categories, and reserve any photography, like the fruit imagery on the food list screen, for content that benefits from a more sensory, real-world feel.
