Customer Reviews

Great App!

I tried a couple of apps but iPeriod is far better than any other. You are able to track your period and ovulation but in detail. You are able to add syptoms or moods during any day which is especially important during the menstrual period. It is very helpfull that you cann save the data on the cloud, have them backed up and more importantly restore them or retrieve them using you account for any other device that uses the app. It automatically generates graphs giving a visual image of the cycle. It provides customization allowing 4 custom buttons for every day and also the theme of the app and the appearance of the calendar and notes can be customised using the inlcuding in the app options. Lastly it can be customised for the pregrancy period and has special section for fertility. Another advantage is the forum which provides a wide range of information. Lastly it has a search option for notes in the history, and it can provide an estimated period cycle for up to one year in the future, similarly for the fertility.

An excellent app imprtant for every woman!!

Handy Tool

A great tool to help track my period. I like being able to add mood and symptoms, it helps to understand the affect my hormones have on me. Easy to use. Great colours and glad I can 'individualise' my iperiod. I like the graphs and while I haven't yet used the print function I think that is a great tool to have too. Impressed with it. Only quibble is that sometimes I have to force quit it (it is still a great application, which is why I gave it 5 stars). But none of my data gets lost and it opens up no problem each time after. Really impressed.

Generally good but crashes

I've tried a couple of cycle-tracking apps on my iphone and tried this for the mac as it seemed comprehensive and allowed the tracking of lots of symptoms etc. It's generally a very good app but unfortunately it crashes or sticks and I have to force-quit. I'm happy with the information I can store but disappointed with the performance of this app.
