Yesterday was my first time trying to go downwind. I'm in Cumbuco - Brazil, and i'm still learning to kite.

For the past 7 days I've been mostly practicing and learning upwind so that I can try to stay in the same place. With teacher!

Going downwind is such a different way of doing it. I managed to go around 8km down but then got really tired. Also fell a lot, didn't have a good flow. Any tips for today? (going again in 4 hours).

This was my session, almost 1200kcals, went to bed at 10pm :D

At the gym, I see many people eating only rice and chicken. Carbs and Protein.
What about pasta, is it worse? Why don't more people eat pasta and chicken for example?

Any Americans here who spend most of the year outside the US?

I’m curious how you keep track of where you’ve physically been throughout the year for tax purposes,especially if you’re moving between several countries.

Do you actually keep a spreadsheet/calendar of every entry and exit, or do you reconstruct everything from flights/passport stamps when tax time comes?

I’m particularly curious about people dealing with things like the 330-day physical presence test or potentially becoming tax resident somewhere because they stayed too long.

Has keeping accurate records ever actually been a problem for you? What have your CPA told you about this?

Thank you team 🤘

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.

My girlfriend and I both travel a lot and we kept losing track of how many days we'd spent in each country. Tax residency rules (the 183-day threshold), visa limits, Schengen 90/180, it all adds up and spreadsheets were always out of date.

So I built DaysAbroad for iPhone. It runs in the background using GPS and logs which country you're in each day. Nothing to remember, it just counts.

The build:

- SwiftUI, targeting iOS 16+

- RevenueCat for subscriptions, restores, entitlement status, and revenue analytics

- CloudKit for automatic iCloud backup, no server needed, data stays in the user's own iCloud account

- Cloudflare Workers + D1 for an optional debug logging backend

- XcodeGen to avoid .pbxproj merge conflicts

- Firebase Analytics (which I forgot to enable for the first release, so I had zero data for a week)

Hardest problems:

- GPS accuracy near borders. If you're standing 50 meters from the French-German border, your phone might flip between countries. I added a confidence scoring system based on GPS accuracy so low-quality readings don't overwrite good ones

- Background location tracking without killing battery. Using significant location monitoring (cell tower based) instead of continuous GPS. The phone only wakes the app when you move ~500m

- The Schengen calculator. Different countries, different join dates, bilateral agreements, and users want to customize which countries count. Ended up making the country list editable

- CloudKit schema not deploying to production automatically. Tested locally, everything worked. Pushed to App Store, sync was broken. Had to manually deploy the schema from the CloudKit Console. Cost me a few hours of confusion

What I'd do differently:

- Start with StoreKit 2 from day one instead of integrating RevenueCat and then removing it

- Add iCloud backup earlier, it was surprisingly easy and users expect it

- Enable Firebase Analytics before launch (rookie mistake)

Revenue model: Free for 2 countries, Pro unlocks unlimited countries, background GPS, multi-year history, CSV export. Monthly ($2.99), yearly ($23.99), or lifetime ($69.99).

Currently a few days post-launch. Downloads are small but growing. The people who need it really need it.

App Store: https://apps.apple.com/app/id6760920831

Happy to answer questions about the technical side or the App Store process.

Hey team, is there an API to access the workout data, or is it in the roadmap? I saw a post from 6 years ago. I want to integrate it on vitaltrends, and right now we only have hevy, would be awesome to also add strong! :)

Playing with the data, trying to improve the way we can visualize and understand, for me, I need to figure out how to improve my recovery, ungently :D

Just finished a light chest workout! Thinking what can I do with all this information!

I am looking for alternatives to send my newsletters.

I've done beehiiv (very expensive), instead of going on SES, I like CF services much more. Can I use it to send, let's say one email per month to 150k users?

Thanks

I've been struggling with getting my "recovery" data up, I usually sleep around 6 hours, but last night I managed to get almost 9 hours, and still bad recovery :(

I am trying, making the room cooler, maybe darker? Also I even built a small diy CO2 sensor to see if the levels are high, as I was reading its supposed to make your sleep quality worse.

Any tips and tricks you do?

Appreciate it!!!

For me it's hard, I usually don't sleep much, last night I had almost 9 hours of sleep, and still tired! Ive event built a CO2 sensor for the bedroom. Maybe no screens one hour before bed? cooler room? darker room? What do you do?

This is the CO2 sensors I built, I can share it if you want :)

Other than google, do you use other authentication methods?
