The 67% also confused me at first. I don't know if I'm the only one but I first thought of a "loading animation" more than the point where you currently are in your development. Now that I know you reference your work in progress, it would be nice to know if you have an idea of a deadline for the 100%. If you're at 67% but started last week or two years ago it's not the same.
I don't know if it's wanted but when selecting text/image the cursor change to look as if I can "edit" your content. And the second screenshot (of the map) in your presentation looks "deformed" (don't know the proper english word, but like it's not to scale).
I'm not sure I would buy this app as is but maybe if you offered more options like export the trips/memories online, share it with friends easily? But it seems that this kind of app already exists in Free (such as travelog, trip journal, etc.) how are you different from them or what more do you offer?
Anyway keep up the good work and add new functionalities!
I find the design looks pretty :-) But what is confusing to me is, that you don't link your Social Media accounts - this should be possible prelaunch.
