## What is Keto Logger?

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: missing-feature@ketologger.com

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 support@ketologger.com so we can figure out what's wrong and fix it.)

### 4/5 — Needs a place to put notes in

*2023-04-22, version 1.1.5*

I like the app but it would help if I could put notes in saying that the reading was after a 24 fast or the reading was an hour after a meal.

### 5/5 — Simple and easy to use

*2021-02-13, version 1.1.5*

This is a basic and easy to use app that assist you in tracking glucose and ketone. I wish you could also track weight so you could view how changes effect weight more easily.

### 1/5 — Cannot edit once recorded

*2020-08-05, version 1.1.5*

Not sure why this app has such a high rating. This app is way worse and frustrating than the free one I was already using. This app does not allow to edit the entry once a record is saved. That’s a bad design.

Note to developer: if you are going to charge for an app, first please provide the most basic feature for a tool. No editing... that’s laughable for a logging app. 

I hope this concern is fixed soon in upcoming updates; then it may deserve a 3 star. UI and controls need a lot of work too. It is messy and clunky AF.

### 5/5 — Beautifully Simple Data Tracker

*2020-07-21, version 1.1.5*

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!

### 5/5 — FIXED: Currently does not work with KetoMojo device

*2019-12-01, version 1.1.1*

Exporting from KetoMojo app start KetoLogger app but no results ever appear!

Edited. 

Well the developer responded quickly an released a fix. Great support. Worth our support!

### 5/5 — Exactly what I need!

*2019-10-26, version 1.1.1*

This app is great, its exactly what I need. Simple, yet powerful. You can log blood sugar glucose as well as ketones. It automatically gives graphs cor Day/Week/Month. You can export data and print or graph and give to your doctor. 

Its pretty much perfect!

### 5/5 — UPDATED Review

*2019-08-21, version 1.1.0*

****UPDATE 8/21****

The developer responded to me quickly and helped me to make changes to my file (which had been corrupted and had some minor errors e.g. capitalizing the header fields). The import worked perfectly...five stars for the app and the quick service. Thanks Rob!

I have tried to edit my .csv to the exact detail required and it will still not import. I have sent a file forward and will re-evaluate my rating and review if/when the developer can fix the app.

### 5/5 — Perfect

*2019-08-15, version 1.1.0*

Love it, meets my needs. And doesn't pilfer my information. Also there are no monthly subscription fees.

### 5/5 — Messwerte

*2019-08-01*

Super App, benutze Sie im Rahmen der Ketogenen Ernährung, bei meinen Schwerbehindertem Kind mit Epilepsie 
gleich die richtige Tabelle und graphische Darstellung
Export klappt super, jedenfalls mit dem IPhone
Danke an die Entwickler dieser App

### 5/5 — Tracks GKI

*2019-07-12, version 1.0.4*

Nothing fancy gets the job done, tracks GKI.
