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.

Dear Elisabeth, We appreciate your feedback and we apologize for the server and network issues. The issues you are experiencing are technically stemming from CycleProGo and that is why we are working diligently on a new release to move over to PeakDay 100%. Please contact peakday@peakday.com so we can assist you further during this transition.

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!

They communicate well with customers. I asked them to solve the problem that this app doesn't pair well with my Google phone and they updated it. Also, they sent me an email to let me know that they updated it. I'm so satisfied.
