Ratings and reviews

This app replaced the CycleGoPro app. In the years I used CycleGoPro, I can't think of a time I had an issue entering my data. Since the switch, I have had repeated issues entering data to where I am considering returning to paper charting for the first time in about 5 years because my charts are so incomplete. I need to try to keep intermittent paper records to accommodate the app errors, which defeats the purpose! PLUS, PeakDay costs almost twice as much as the old app which actually worked!

Guys, you HAVE to go back and optimize this thing. It's running SO slow. It loads for 10 seconds every time I switch months, and sometimes it takes 5 seconds to register my click on a day. And since whenever you finish entering data it automatically takes you back to the current day on the calendar, this makes going back to enter older data an absolute nightmare.

I used CycleProGo (the previous version of PeakDay) for years with no issues. I had high hopes for PeakDay. It looks nice and is intuitive to use. However, in the months since PeakDay came out, there have been regular outages (sometimes multiple times in one week). They do get resolved and my data is restored, usually within a day; but I want a reliable app that always opens every morning. Unfortunately, I will not be renewing my subscription.
