About Dynvybrigh Tir
Dynvybrigh Tir is an independent editorial project that compares nutrition apps and supplement brands for readers in the United States. We do not sell any of these products and we have no ownership tie to the brands we list. The aim is straightforward: tell you what we found using each one ourselves, the way an ordinary customer would.
How we work
For every brand in the comparison we buy a real subscription or order the supplement and use it for weeks. We compare features, plans and how the product feels in daily life, weigh how it handles your data, and check whether the habit actually holds. Only then does a brand get a score. We do not copy descriptions off product pages, and a brand cannot pay for a better place.
How we're funded
Affiliate links pay for the site. If you sign up or buy through one of our links, the brand may pay us a commission, at no extra cost to you. This does not change the order of the ranking; a brand only moves up if it performs better in our testing.
The desk
Marisa Ellery
Senior Reviewer
Marisa has written about nutrition apps and consumer supplements for more than six years and keeps an active account on every service we recommend. The testing here runs out of a home kitchen in Austin, across calorie trackers, a behaviour-change app and a handful of daily supplements, judging each over weeks rather than a first impression.
