About this app

Your Fitbit data, beautifully visualized — and entirely on your phone.

Apex Trace turns the health data you already track into a dark, animated dashboard worth opening every morning. It reads your data through the Google Health API and renders it as ring gauges, real hypnograms, activity heatmaps, and long-term trends. No flat charts. No monthly bill.

PRIVATE BY DESIGN — NOT BY PROMISE
Most health apps ask you to trust their servers. Apex Trace doesn't have any.
• No backend. Your health data never leaves your device — there's nowhere for it to go.
• No account, no tracking, no ads. Nothing to sign up for, nothing following you around.
• Limited Use. Apex Trace's use of Google data follows the Google API Services User Data Policy, including the Limited Use requirements: your data powers only the features you see — never advertising, never sold, never used to train AI.
• Optional crash reports are off by default, and never contain health data.
Disconnect anytime and Apex Trace revokes its access and wipes every cached byte from your device.

WHAT YOU GET
• Today — your whole day at a glance, with animated ring gauges and an at-a-glance readiness estimate computed from your own data.
• Sleep — a real hypnogram showing stages, timing, and how last night compares to your baseline. Finally readable.
• Fitness — activity heatmaps and heart-rate zones that show effort and consistency over time, not just a single number.
• Trends — long-term patterns across your metrics, so you can spot what's actually changing week over week and month over month.

PAY ONCE. $6.99.
No subscription. No in-app purchases. No ads. Buy it, own it. Get premium-style daily estimates without the premium-style monthly bill.

TRY IT BEFORE YOU CONNECT
Apex Trace ships with a full sample mode, so you can explore the entire dashboard with example data before you buy or connect anything.

WHAT YOU'LL NEED (companion app)
Apex Trace reads your data through the Google Health API, so it needs:
• The Google Health app installed, and
• A connected account syncing into it (a Fitbit account is the most common source).
Apex Trace does not connect to Fitbit directly, and there's no account to create with us.

A NOTE ON THE NUMBERS
Apex Trace's readiness, sleep, and cardio-load figures are its own estimates, computed on your device to help you spot patterns. They are not medical advice, and not any other product's official scores.
