Just got this for my Apple devices and it is outstanding. If you are a regular traveller or doing a complex journey this helps so much and I really recommend it.
It takes your booking confirmations, diarizes them, keeps all the info in one place and automatically updates new aspects of the journey.
I am about to go 4 countries in 6 weeks with multiple flights, hotels, hire cars etc and it has slotted the lot into one beautiful itinery.
I love it!
