Well - not that easy as shown in the videos.... And I shouldn't have a language problem as the guy explaining the new app in the German video is an Austrian (and so am I).
Couldn't find a possibility to get the data over into the android app.
So leave the phone aside and go for the I-pad. Ok, this works. I can email the old data to myself, and then open with the new z21 app. Now the easy way to move it to the other devices: tried the export function, no device found. Well 2 of them are next to me on the table. May be not then.
A bit later I uploaded the old data also to the android phone. But this is not what I expected - the easy upgrade from one device to another needs to be found.
As a general impression I can say that the display of the new app is darker than it was. As model railway is a subject also (or mainly) used by the rather settled or experienced generation - not to say by older people - this is a disadvantage.
Looking into the database story: It is not clear what is the search key to get info and a loco picture from their database. I put in a new Roco loco (Well - new - I don't know for how long it was waiting for a customer on the shelves of A&H models) and the system doesn't find anything. I checked the article number as I thought this might be the search key - well it is correct as far as I can see.
OK. Give them a chance. I start creating a new loco, and I scroll through their database. Lovely, my loco is not in the database, and the database searches "in circles - means when you at the end it starts with the beginning. Took me some time to say - bother they are repeating the same loco again and again....
Well - what do we learn? Buy yourself a popular loco, then everything is available. Buy yourself an OBB 1141 and you can do it yourself.
For the more popular locos - yes the article number is the key. It still makes sense if you think of a more complicated (popular) loco with sound. You get all your function keys set in a flash.
As it looks there is currently no new software version for the I-pod.
Hope you do not consider everything I wrote as moaning - but it is not that user friendly as said in the video.
I still like that there is something moving, and new versions are created. Lets hope it gets a bit better described in the near future.
Will look into programming later.
