Why Kygo
There's a better way to understand your health
Your wearable shows what's happening. We show you why.
The old way
You log for months and learn nothing
Your score drops and you never find out why
You cut foods that were never the problem
Logging takes so long you quit by week two
The Kygo way
Answers start showing up in 7 days
See what moved your HRV, and by how much
Stop cutting foods that don't affect you
Photo, voice or chat, all under 10 seconds a meal
How it works
From first meal to real answers
Three steps. About a week of logging. Patterns you can actually act on.

Why I built Kygo
Ryan · Founder, Kygo Health
I wanted logging that takes seconds, not minutes — and insights that align to your individual metrics and diet, not generic advice. That's why I built Kygo.
"Your sleep latency increases 8 minutes when you consume caffeine after 3pm." That's not from a study—that's YOUR body telling you something specifically.
Kygo brings everything together and automatically finds the correlations that matter. No more guessing. No more generic advice. Just personalized insights based on YOUR data.
I hope Kygo can make a positive impact in your life as well.

Web
Read your correlations on a full-size screen at app.kygo.app, and connect Oura, Garmin, Fitbit, WHOOP, and Polar right in the browser.
One account and one plan cover all three. Sign up once and iPhone, Android, and the web app are included, so nothing is bought twice and nothing has to be re-entered.
Questions & answers
Frequently asked questions
Everything you need to know before you start. See the full help center.
Is my health data secure?
Yes, protected end to end. All traffic is encrypted with modern TLS and your data is encrypted at rest with AES-256, on accounts secured with bcrypt hashing and token-based authentication, with every request scoped so only you can reach your own data. We never sell your data. Your wearable connections use official OAuth you can revoke anytime, and deleting your account permanently purges your data. Read our privacy policy →
What is Kygo?
Most apps show you a sleep or HRV score and stop there. Kygo, available on iPhone and Android, connects your wearable data to your food and supplements so you can see why your numbers move, not just what they are. Logging is effortless: snap a photo, use your voice, type it, or scan, with no manual database searching. Connect Garmin, Fitbit, Oura, Apple Health, and Health Connect to pull the most accurate metrics from each device.
How is Kygo different from MyFitnessPal?
MyFitnessPal tracks calories for weight loss. Kygo shows you how food affects your sleep, HRV, energy, and recovery by correlating your nutrition with your wearable data. It’s not about dieting, it’s about understanding your body’s unique responses.
Which devices do you support?
We integrate with Oura Ring, Garmin, Fitbit, WHOOP, Polar, Apple Health, and Health Connect. You can connect one device or multiple, we’ll combine the data to fill gaps and give you the most complete picture.
How long until I see correlations?
Basic trends show immediately. Meaningful correlations typically appear after about seven days of consistent logging. The more data you provide, the better and more accurate your insights become.
Is it really free?
Yes! Voice, barcode, and text logging, wearable sync, and trend tracking are free forever, plus 5 AI photo scans a month. Pro adds food-body insights, supplement tracking, unlimited photo logging, a daily factor spotlight, and nutrition write-back to Apple Health and Health Connect, for $9.99/month, $49.99/year in the apps or $39.99/year on the web, or $99.99 once for lifetime access. The yearly plan includes a 7-day free trial.
