Love it


Love this app. Only wish I could connect the info I’ve been saving and journaling to my overall ‘Health’ app, the one that comes on iPhone.

I’ve recently decided to start trying to track more of my lifestyle info. Seems I’ve had a sudden desire to see how healthy my everyday life truly is. Then, the plan is to, anyhow, compare and contrast to c ifin I should rethink my fitness status. Never been one to really think much about this stuff nor track it. It’s new to me.

That makes this a nice app. It is easy to use with many options. U can be as simple or as complex with ur notes as u like. Ur able to track periods, sexual activity, moods, medications, and many many more, with nearly ea having more sub-options.

Totally worth a try. I love it. Just want to suggest that app becomes linkable to ‘Health’

It’s very valuable, but...


It’s not crossing to my other Apple devices. It’s on my iPad, but I can’t download to my iPhone. It would be nice if they added an account option, so the information can cross to every device you have. I tried it on my iPhone and it wants me to input all my information again. If I had known, I would have downloaded it to my iPhone first, so I can carry that information around with me. Please add an account option!

Developer Response

Hello! Thank you for the feedback. We do have plans to add option to synchronize the app between Apple devices in one of the future updates, thank you for the suggestion. With more comments please contact us at Thank you.

Easy and Clear


This app is very easy and clear to use. I would recommend this app more towards younger girls who have just started their period but this can also work for others. The only question I have is why this app is for 4 year olds and up?
