Overview

A workout log that stays out of the way

Chalk is a mobile workout tracker designed to replace paper notebooks with a clean, distraction-free interface. The focus is on speed: open the app, log a set, get back to lifting.

Problem & Motivation

Why most gym apps miss the mark

Paper notebooks are impractical

At the gym, a smartphone is always within reach — a pen and notebook rarely are.

Existing apps are bloated

Most workout apps are crowded with social feeds, leaderboards, ads and paywalled basic features. 

The goal is speed

Create a clean, distraction-free tool that lets lifters record sets, reps and weights in seconds.

UX Process

Low-fidelity wireframes

Low-fidelity wireframes established the core structure across Home, Routines, History and Profile before any visual polish was applied.

High-fidelity wireframes

Refined screens that keep the same information architecture while adding visual hierarchy, clearer tap targets and a polished grayscale interface.

Final Deliverables

Final UI — Light mode

The shipped light theme: soft neutral surfaces, mint accents for progress and records, and high-contrast ink for everything you read mid-set.

Final UI — Dark mode

The dark theme keeps the same mint accents on deep ink surfaces for low-light gym environments and reduced eye strain during late sessions.

Project Status

Active work in progress

Chalk is currently being developed toward a public app release. The goal is to offer a minimalist alternative for everyday lifters who want to log workouts without the noise.
