Affordable Alternative to Natural Cycles – Works Perfectly with Manual Input.
I’m a total numbers girl and love keeping track of what’s going on with my body. I’d used Natural Cycles before, but when I saw how much the subscription had shot up (ouch!) I started looking for an alternative. I went for this one after finding out about the Femometer app. This particular thermometer isn’t Bluetooth (so it doesn’t link automatically), but honestly, the app still works perfectly well with manual input. Most importantly ... it’s free! The thermometer itself is really good quality, super easy to use, and comes in a sturdy plastic case to keep it safe. It gives accurate two-decimal readings and feels well made. I have had no issues with battery life and it's super easy to clean. In terms of storage - its pretty small so slips into a bedside draw easily without taking up loads of space. Overall highly recommend! Great value for money, and I’d definitely purchase again.

The best thing I used to NOT get pregnant!
I got this thermometer, because my partner had had a vasectomy after us having a devastating loss. we decided we didn’t want any more children, so he went for a vasectomy and I purchased this so it made peace of mind for me knowing to abstain when I was ovulating. It worked a treat! Knowing how my body works is so empowering, and I highly recommend this to anybody who is trying to get pregnant or not! It’s also very handy because I know exactly when I’m due on my period too, and it has never been wrong!

Really simple to use and great app!!
Why did you choose this product over others?: Really simple to use and has an app that is really easy to use. There's an option to pay a subscription fee to upgrade the app to a better version but I've just been using the free version and it seems alright so far! Would definitely recommend a is a much cheaper option that others found.

Not reliable
Seems very unreliable. I take my temp 3 times in a row and it's very different (up to .13) every time. Considering it's meant to be highly accurate to track fertility, it's not very udeful

It is NOT reliable
It doesn’t work, it is very variable, I take the first three temps and then average them. I would say you should use this to measure your basal body. I would return but I’m now outside the return window. I ordered a different thermometer to see if I can get a more realizable reading

Good
I had to correct my review. I have to say that the app is very much into detail and so it’s not the easiest. The free version is good but it took me a while to understand how to use it free. My advice is to pop a step by step on how to use it free as its actually great and the paid version looks amazing So I’m editing my review as it was me and not the app!
