This or That

Two photos, ten seconds, one answer — with reasons under it.

You are in the fitting room holding two things. There is nobody to ask. The message you sent your friend has been sitting unread for twenty minutes, and the assistant has already said “they both suit you”. So you either buy the wrong one or you leave with neither.

This or That ends that in ten seconds. Add two photos, tap where you are wearing it, and shake the phone. One of them gets the light. The other goes dark.

What it does

Names a winner. Never “both are lovely” — that is the problem, not the answer.
Shows its working. Four reasons with a score on each: right for the room, colour under this light, line and shape, and whether it sounds like you.
Tells you what would have flipped it. One line: the condition under which the other one wins.
Judges the price too, if you want. Type what each one costs and a fifth reason joins in.
Knows your taste. Tell it your colours and your style once; it shows up as a reason you can actually see.

What it will not do

It scores the item, never the person. If you are in the photo, the analysis stays on what you are wearing — there is no attractiveness score, no body assessment, no comment on you. That is a permanent rule, not a setting.

There is no feed, no voting, no strangers. Nothing you photograph is ever visible to anyone else.

Your photos go nowhere

Your two photos are sent for analysis only after you have agreed, and they are discarded the moment the answer comes back. They are never written to storage — the app does not even include a storage library, so no code path can. Your history and your photos stay on your phone, and nothing syncs.
