It is fantastic and definitely warrants five stars. It’s disappointing that it’s Apple only – I was hoping to switch between my laptop and iPhone, and although it’s expensive monthly, five minutes into the free trial I understood exactly why. This app is intuitive, you can create sub-timelines, add categories and filter by category, color code, and add photos. The option to click your event and have a world of further presentation options is amazing. My one complaint would be that the default text size is very small on my phone when I type into a textbook – an option to increase the default text size would be great. Again, this is Apple only, but it’s impressed me so much that I won’t rate lower than five stars.
