About Holt
Holt is a GLP-1 tracker for iPhone. It helps people taking medications like Ozempic®, Wegovy®, Zepbound® and Mounjaro® keep a calm, complete record of their treatment — doses, meals, side effects, weight and water — and see how it all connects.

Why we built Holt
Starting a GLP-1 changes a lot at once: a new routine, a quieter appetite, side effects to understand. We built Holt so that keeping track takes seconds, and so the record you keep is genuinely useful — to you, and in the conversations you have with your prescriber.
What we believe
- Calm over pressure. No streak-shaming, no guilt — just a clear picture of your week.
- Eat enough of the right things. Protein, fiber and water matter as much as eating less.
- Your health data is yours. We never sell it or share it for advertising.
- A tracker, not a clinician. Holt never tells you to change your dose — that’s your prescriber’s job.
Who makes Holt
Holt is made by Ace Studio, an independent software studio. Otto the otter keeps everyone company along the way.
