Wall of TruthThe wall doesn’t lie.
Wall of Truth turns your Apple Health data into a GitHub-style activity wall — one square per day, colored by how hard you showed up. See a whole year of effort at a glance, and keep the streak alive.
Your health data never leaves your iPhone.
Six metrics, straight from Apple Health
- Steps
- Hours of Sleep
- Calories Burned
- Exercise Time
- Standing Time
- Floors Climbed
Consistency you can see
Averages flatter you. A wall of daily squares tells the truth — and that’s exactly what makes it work.
One year on one screen
Every metric gets its own GitHub-style heatmap. Dense green weeks, pale gaps, comebacks after a cold — your training history becomes a pattern you can actually read, not a number buried in a chart.
Zero manual logging
Wall of Truth reads steps, sleep, calories, exercise, standing time and floors climbed directly from Apple Health. Open the app, the wall is already up to date. Tap any day for detailed stats: totals, averages, best days.
Your wall, your rules
Pick custom colors for every metric, set your own thresholds for what counts as a green day, switch between light and dark themes, and lay a full year out in multiple rows. Your definition of a good day, not ours.
A streak that stares back
Home Screen widgets put your wall where you can’t ignore it. Every time you unlock your iPhone, the empty square for today asks the same quiet question: are you going to fill it?
Private by design
Your health data stays on your device. No account, no cloud, no analytics on your workouts, nothing to sell. The only person watching your wall is you.
Frequently asked questions
What is Wall of Truth?
Wall of Truth is a fitness tracking app for iPhone that visualizes your Apple Health data as GitHub-style activity heatmaps. Each day is a square, colored by how active you were, so a full year of steps, sleep, calories or workouts fits on one screen.
How does the GitHub-style heatmap work?
Just like a GitHub contribution graph, every day is one cell in a grid. The more you move, the darker the green. You set the thresholds, so you decide how many steps or minutes of exercise it takes to earn the deepest color.
Which health metrics can I track?
Wall of Truth tracks six metrics from Apple Health: steps, hours of sleep, calories burned, exercise time, standing time and floors climbed. You can enable or disable each metric individually.
Do I have to log workouts manually?
No. Wall of Truth syncs automatically with Apple Health (HealthKit). Anything your iPhone or Apple Watch already records — walks, workouts, sleep — appears on your wall without any manual entry.
Is my health data private?
Yes. All health data stays on your device. Wall of Truth has no account system, no cloud sync and no third-party analytics on your health data. Deleting the app deletes the data.
Can I customize colors and goals?
Yes. Every metric has a customizable color palette with a full color picker, plus configurable thresholds for each intensity level. Light mode, dark mode and a multi-row year layout are included.
Which languages does the app support?
Wall of Truth is available in English, Spanish, Catalan, French, German, Italian and Japanese.
