Why FitLatch
Three reasons it’s different
01
Built on your data, not a quiz
FitLatch connects to the apps and wearables you already use — Apple Health, Whoop, Oura, Hevy, MyFitnessPal — and builds your stack from how you actually train, eat, sleep, and recover. No guesswork, no generic questionnaire.
02
"Did It Work?"
FitLatch tracks the metrics you care about and shows how they move alongside your stack — correlation in your own data, so you can see whether it's making a difference. The feedback loop no brand-locked competitor can replicate.
03
Brand-neutral and honest
We're not locked to any one brand. FitLatch recommends what fits your data — and tells you when to stop something that isn't pulling its weight. No upsell, no house brand to push.

FAQ
Questions & answers
How does FitLatch personalize my supplement stack?
FitLatch connects to the apps and wearables you already use — Apple Health, Whoop, Oura, Hevy, MyFitnessPal — and builds your stack from your real training, nutrition, sleep, and recovery data, not a one-time quiz. Your stack is organized into AM, pre-workout, PM, and bedtime packets.
What data sources does FitLatch use?
Apple Health, Whoop, Oura, Hevy, and MyFitnessPal at launch, with more integrations planned. You choose what to connect; recommendations are built from the data you share.
What is the "Did It Work?" report?
It tracks the metrics you care about and shows how they move alongside your stack — correlation in your own data — so you can see whether your supplements are making a difference instead of guessing.
Is FitLatch tied to one supplement brand?
No. FitLatch is brand-neutral: recommendations are chosen to fit your data, not to push a house brand — and FitLatch will tell you when to stop taking something that isn't earning its place.
