Slyra works out what you need and tells you what’s left, meal after meal. And AI makes logging easier: when a food can’t be found, it fills in its values for you.
What research says about tracking, and what Slyra does with it.
Up to 66%
of dieters regain more weight than they lost. Slyra is not a diet: you keep what you like, and see where you stand each day.
Mann T. et al., American Psychologist, 2007
In a study of nearly 1,700 adults, those who kept a food record every day lost twice as much weight as those who kept none. That is what Slyra makes simple.
Hollis J. F. et al., Am J Prev Med, 2008
Noting your meals soon becomes a habit. Across 39 trials, regular digital tracking went with weight loss in 74% of cases. In Slyra, your recent foods come back in two taps.

I had tried several nutrition apps, but none of them was really easy to use, and I always ended up giving up. I created Slyra to finally have an effective, simple tool to track my health, with AI making everything you can do in it more effective, today and tomorrow.
