User Reviews

Users praise MyDays X Pro for its simple, no-frills design and accurate cycle predictions after accumulating data, plus reliable backups for device switching. However, feedback highlights recurring problems: backup failures and data loss; persistent ads or ad-related prompts even in paid versions; privacy-related prompts and data collection; app crashes/freezes after updates; and missing or broken moon phase/prediction features. These issues raise reliability and data-migration concerns.
Pros
  • Simple, no-frills, easy-to-use interface.
  • Accurate period/start date predictions after accumulating data.
  • Reliable backups and easy device switching to preserve long-term data.
Cons
  • Backup failures and data loss when backups fail or are unavailable.
  • Ads persist or ad-related prompts even in paid versions; intrusive monetization.
  • Privacy concerns: prompts to share personal data, data collection, and location tracking; data selling.
  • Crashes or freezes, especially after updates or when using the paid version.
  • Moon phase feature missing or not functioning / predictions unreliable.

I’ve been using this app for years and it’s been very accurate as to when I would be starting my period. I do wish there was an option to sync my data history with Apple Health.

I’ve used this app for so many years and I love it. The only thing I think is missing are the moon phases that I would like to keep track of beside my period.

I’ve loved this app for as long as it’s been a thing. I hate the newer apps because they aren’t as simplified to me as this one. I don’t want an all girly and baby-like app. I’m not against either things, I just haven’t liked any other app layouts or anything. This app isn’t all about the frills but allows you to make changes. The problem is, within the last month or so I feel as if something has happened to ruin it and I’m just now seeing it. It could be further back since I haven’t played around with things lately but I’ve continued to log my periods and they aren’t there. I have my account set to auto-backup but it seems that it hasn’t done that. When I try to reload, it goes back nearly a year! This is unacceptable. Where’s my info?! As for ads, I don’t have them…just pay for it. It’s worth it.
