Vitaltrends: the Whoop companion app I didn’t know I needed (recovery trends, multi-device HR, training logs, AI/MCP)
Hello fellow Whoop users.
I wanted to take a minute to share an app I found here on this subreddit about a month ago that has seriously changed how I analyze my fitness and health data.
https://www.vitaltrends.net is a dashboard that pulls in your historical Whoop data along with Apple Health, Withings, Oura, and others, then presents it in a clean, insightful way. The Whoop app is limited when it comes to true longitudinal views and broader historical context — this fills that gap really well.
One of my favorite views is the recovery history. Being able to see recovery trends over long periods and quickly spot the dips and peaks has been huge for me.

The biggest reason I keep coming back, though, is the ability to combine datasets into a single visual. I’ve been paying a lot more attention to heart rate accuracy lately because it’s the foundation of almost every Whoop metric. I wear Whoop, an Apple Watch, and a chest strap (Polar) during workouts. All of that data lands in Apple Health, and Vitaltrends lets me overlay the different HR sources on the same workout page so I can actually see how they compare. Below is a Pickleball session lasting almost 4 hours where I tracked all three and was really confident that Whoop is tracking my heart rate accurately compared to the other two devices.

The data categories doesn't stop there as recently the developer has incorporated a Training log section where you can see historical weight lifting activities including muscle groups worked and detailed pages on a session which can incorporate heart rate data into for a complete picture of your workout.

On top of that, the developer has added MCP support so you can connect Claude, Cursor, Grok, and others directly to the data. I keep a lot of other health info (bloodwork, nutrition, etc.) in Google Drive and can ask very specific questions that pull from both sources. It’s been useful for looking at training load, meal timing, and potential supplement adjustments.
u/danskubr is the developer and has been extremely responsive — fixing bugs quickly and adding features based on feedback. One recent addition I requested was blood pressure tracking from Apple Health (I use an Omron cuff a couple times a day). It now shows up cleanly in the dashboard alongside everything else.
As someone who prefers to review and analyze my data on a computer as opposed to being stuck on a small screen like an iPhone or Android phone I truly appreciate the capabilities and constant communication of Daniel and the Vitaltrends app.
