Needs a place to put notes in

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.

Response from developer

Please scroll down in the reading entry screen to add notes.

Simple and easy to use

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.

Cannot edit once recorded

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.

Response from developer

Hello. To edit a reading just tap on the reading from any of the the "history" views. In the glucose or ketone views you can tap anywhere on the line. In the "both" view tap directly on the reading. Once you tap, the edit view will pop up. Do your change and press "update" on the top right.

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!

FIXED: Currently does not work with KetoMojo device

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!

Response from developer

Update: Please update to the latest version of Ketologger ( v1.1.1). It turns out that the generated KetoMojo CSV file can have either 12 or 24 hour time which was unexpected. The latest version adds support for 24 hour time. Another Canadian user experienced that problem. --- The Keto Mojo csv file is supported for import. You should either see the import helper screen or a screen that says there was an error and offers to upload a sample file securely and anonymously for analysis. That would indicate that the file was successfully sent to Ketologger. Please take a look at this FAQ entry for more information: http://ketologger.com/blog/2019-08-08-ketologger-import-export-readings-csv If that doesn't help then please send a mail to support@ketologger.com so we can figure out what the problem is.
