What's New in kegg

3.0.7

September 17, 2026

What's New: • Your Home screen and post-reading messages now show the same cycle phase as your fertility status, so you will no longer see "Luteal Phase" next to a high fertility reading. • Fixed an issue where the app could get stuck on a loading screen or sign you out unexpectedly. • Clearer options when logging a period: choose "Start new period" to begin a new cycle, or log spotting or unusual bleeding without starting one. • Stability and performance improvements.

New update terrible

New update is giving false readings and testing is way off so disappointed I really had high hopes for this and is not cheap either!

Great until recently.

I loved this before the update. Since then, I get "unknown" for both my score and fertility status, no matter how many times I take my reading.
I probably will no longer use this method of family planning.

Still not pregnant

I have been using kegg religiously since February and I’m still not pregnant. I did the app update this morning and it is, as respectfully as possible, horrible. The old interface was much more attractive. This new interface is zoomed in so far you can’t really see the big picture. not to mention it no longer shows the ovulation prediction bars. I wish there was a way to zoom out so you could see the whole cycle. This feels like it’s zoomed in for an 80 year old wearing reading glasses. It also is not very useful since it gives me about a 10 day fertile window. LH strips are much more accurate. I really wanted this to work. I was lured in by the six month guarantee (which looking back is quite predatory on women who are already struggling through so much grief and uncertainty), but having tried it for six months and reading the stipulations… I realize I’ll never get my money back. I used it every day for 6 months. Every day. But one month we were told to skip conception efforts by our doctor, which I guess resets the 6 month timer. They make it basically impossible to actually get your money back.

Got Pregnant Within 3 Cycles

I snagged the Kegg when it had a 6-month guarantee for pregnancy. I thought why not? First, I do feel like it’s very accurate with predictions. I had been using LH tests and had read they can sometimes read ovulation late. When using Kegg, my ovulation was a few days later than my LH tests indicated. The best part about this was I used it for about 3 cycles before deciding to try and get pregnant. So on my 3rd cycle, I listened to when it recommended intercourse, and I got pregnant first try! I highly recommend this even if you’re not trying to get pregnant. ***The only thing I wish it had was an included pregnancy tracker!!!***

Got pregnant on the first try

I have been using the tracker since February to gain an understanding of my cycle. When we decided it was time to start trying, it happened in the first month! I am 38 and never expected it to happen this quickly. Thank you, Kegg!
