KetoLogger will help you quickly and easily log and graph your ketone and glucose readings.

Enter your glucose and ketone readings with ease via the simple to use entry screens. Both mg/dL and mmol/L glucose units are supported.  

You can import the CSV files from the KetoMojo meter app*.

The graph tab helps you visualize your glucose vs. ketone readings with a line graph. Quickly see how you're doing with a glance. Jump quickly between date ranges to get the best picture of your progress.

The history view lets you see your readings. Either glucose, ketones or using a "Both" view. In the Both view matching glucose/ketones readings are paired and the GKI is calculated.

Easily export all your readings in CSV format (Two formats to chose from).

A "backup manager" maintains the last few versions of the database. These can be restored or exported. Share your database between devices.

If there's a feature that's missing please let us know at:

GKI graphing is in the works (not sure when it will be done) but was originally skipped because I figured that graphing ketones vs glucose creates a kind of visual GKI. See my thought on GKI here:

Keto Logger was inspired when a family member was following a ketogenic diet for health reasons. For a programmer logging and graphing ketones in a spreadsheet is not too challenging. For most other people probably a huge challenge. Keto Logger was created so that anyone with an iOS device can log and graph their ketone and glucose readings. (Also I personally have been following a low carb/ ketogenic diet since about 2003.)

(* CVS import is tricky and will break if the exported format changes. If import fails then please send a mail to so we can figure out what's wrong and fix it.)

Beautifully Simple Data Tracker

I’ve been keto for years now, but recently gotten into intermittent and extended fasting so I decided I wanted to do more comprehensive tracking to see how fasting affects my levels vs. just keto alone. I have pretty much tried every app available that tracks ketones and glucose, and only one even comes close to matching the functionality of KetoLogger. KetoLogger wins hands down because of its ease of use. No clutter from things I don’t need like meal logging/intro to keto articles/social functions. I have other apps for food logging and just wanted something where I could easily see my ketones and glucose in one place, and as a data lover the overlaid graphs is a huge plus. Don’t be afraid to pull the trigger on the price, you’ll get way more out of it than your daily Starbucks coffee. For advanced ketoers, this app is just pure gold.

Also, I contacted the developer about a small issue, and he his response was quick and thorough. He’s got plans for updates, so the app is only going to get better!

Simple Great App!

I make it a rule not to buy apps that do not offer free samples, and this one doesn't. I hesitated for a few days before I hit the "Buy" button, but I'm glad I did.

I had been searching for an app to log blood ketone and glucose levels. I've been on a low carb diet. I wanted to 1) make sure I'm in ketosis, which is my goal of being on a low carb diet, and 2) measure how much impact certain food has on my glucose/ketone levels.

I searched and tried a number of apps (free and freemiums) but none of them were satisfactory. Some require a lot of taps and key strokes. Others are designed for people with diabetes, which I am not, and lacking ability to track ketone levels. Most apps that have "keto-" in their names focus on diet, asking you to enter a whole bunch of information on what you eat. I don't care any of that. I have a ketone/glucose meter so I know if I am in ketosis or not by measuring the blood ketone level, without having to enter all the food data.

This app addresses my needs exactly. As the screenshots show, it has easy "dial" to enter values with time of entry, displays graphs to see the ups and downs. Very easy to use. Minimal taps required.

A few things to be desired in future updates... 1) Connectivity to iOS's Health App. 2) Option to enter food intake (meals & snacks) to track what triggers changes in ketone/glucose levels.

But overall, it's a perfect app. Highly recommended

Worth it

Experimenting with low carb, keto, and fasting. This app provides a visual representation, and helps me see important relations between
(On the one hand)
—my nutrition (or lack of!) in the last few hours, and
—how I feel

And (on the other)

—my blood sugar, and
—my ketone (alternate fuel/fuel from fat) levels

With this, in time, I hope to have a strong internal sense of these.

So, it’s incredibly important, what this app helps us do. And I’m pleased with how it does it.

One suggestion might be adding the readings for hematocrit and hemoglobin, which these blood tests also provide. Another would be allowing the app to sync with keto mojo, et al, test company apps. . .

And this brings me to another point. I suggested this to the maker of the app. He was incredibly responsive. And said he was already on one of those. My hat is off to him.

I have no relation, financial or otherwise, to the app or it’s maker. But I’ve found it useful. And given that the costs of a blood test or two exceed the cost of this app, I don’t think you can go wrong in using it to track many of these tests. It is the best app I’ve found to do so. And in doing so, it does not require sharing a lot of personal info either

Developer Response ,


Thanks for the very kind review. Version 1.1.0 has the ability to import from Keto Mojo (the formats I'm aware of or submit a sample file if it has changed). Hematocrit and hemoglobin aren't yet supported but some of the work "under the hood" for this last update is paving the way for addition of other reading types.
