Still using this App. Cannot believe its free.

UI is why only 1 Star

First time user review after enjoying years of TripCase. This app cannot create and save a template that contains folders Notes-Flights-Ground Transport-Hotel-Map-Food-Photos then be able to copy paste that into a block of dates. It can only be done one day at a time and it’s hard based on the UI. Events I don’t want it sync to any calendar I want to create on my own a single event ! More later once I have used it some more.
I don’t need nor want my entire calendar in this app. Reducing this review from 2 stars down to 1 star and there is no undo feature.

Response from developer

Hi, sorry you didn't find the app useful. iStratus is a comprehensive personal organization app that focuses on daily planning rather than travel-specific needs. If you have suggestions we would appreciate it if you could contact us directly at support@istratus.com

Nice

It would be great if we could share files and calendar with other stratus users.

Also, if for some reason my app got deleted I lose all my saved data. I can’t put effort on something I might lose forever.

I really hope you work on my suggestion. And would be great to get a reply from the developer
