Who makes Keel, and how.
Keel is made by one person. This page says who, why, and how the numbers on this site and in the app are sourced.
Who makes it
Keel is designed, built and supported by Ihor, one independent developer. There is no team behind a support queue: if you write in, he replies.
Why it exists
GLP-1 medication turns the usual problem around. With appetite suppressed, the risk is no longer eating too much — it is eating too little of what protects lean mass. The instruction most people are given, eat more protein and lift weights, comes with no number and no way to tell whether you did it.
Calorie apps are built for the opposite problem, and congratulate a day on which you barely ate. Keel gives you a protein floor instead of a calorie ceiling, and one word each day for whether you cleared it.
Where the numbers come from
Every number Keel shows traces to a record. Your protein floor is worked out from published research, and the calculator shows each step of it with its source. The same code runs on this site and in the app.
Food figures come from USDA FoodData Central and Open Food Facts. When you type what you ate, an AI model works out which food and how much. It never supplies the grams — those come from the database. If a figure cannot be sourced, Keel shows none rather than a guess.
The articles on this site cite their sources at the foot of each page. Where the evidence is thin, they say so: no trial has yet tested a protein target in people on GLP-1 medication specifically.
No account, and your data on your phone
Keel has no account and no password. Your subscription travels with your Apple Account. What you log stays in the app's own database on your phone and in your normal iPhone backup — there is no copy on a server. Analytics never receive a weight, a protein figure, a medication or a dose. The privacy policy says exactly what leaves the phone, and to whom.
It tracks and educates. It never prescribes.
Keel is not medical advice and does not diagnose or treat anything. It records the medication you were prescribed; it never recommends a dose, a titration schedule, or when or how to stop. A target your clinician sets always overrides Keel's number. Discuss your medication and your diet with your prescriber.
How this site is written and reviewed
The articles on this site, and the explainer under the calculator, are written by Ihor. They have not yet been reviewed by a clinician, and each one says so. Each carries the date it was last reviewed, and is revised when a source changes. If you find a claim that is wrong or out of date, please say — that is a fault worth fixing.
