The most intelligent
nutrition tracker,
built for peptides
Meals, protein, doses, and progress in one iPhone app, for the months when appetite is low and the details still matter.
Most trackers are built to count calories down. Peptides change the job. Appetite drops, muscle is at risk, and dose days shape everything around them.
CalTrak+ is a nutrition tracker rebuilt for that window. It adapts targets on low-appetite days, protects the muscle you've built, and keeps doses, side effects, and progress on one timeline.
Built for the window
Your peptide months are a window. CalTrak+ makes them count.
The window doesn't wait.
Peptides work, but what you do while they work decides what you keep.
Lean mass
40%
of the weight lost on a peptide can be lean muscle. Daily protein targets are how you keep yours.
After stopping
2 in 3
pounds can come back within a year of stopping. The habits you build now are the ones that last.
Logging
10 sec
to log a meal with Eve AI: a photo, a voice note, or plain words like “a large latte.”
