I've spent the past months building pikapp.in, program for distributing photos effortlessly. So, what we've have noticed is usually, we have lots of events, weddings, school events, etc.
But there is not a reliable way to distribute photos.
So, we've built pikdapp, where the host can upload all the photos they have, get a QR/link and then share that with the guests at the party.
The guests then, can easily scan their face, and get all their photos.
Would love to hear feedback!
