The logo is not simple enough to clearly see on small mobile screens and the name sounds (to my ears) neither ‚professional‘ (Photoprism or LibrePhotos) nor ‚playful‘ (Tiddlywiki, Lychee). This is both quite subjective, so your mileage may differ wildly.
Of course, it takes nothing away from the app – I use it very happily on a daily basis. I just wish these things will be changed one day, then I will be even happier. 😁
