Psst is a shared shopping list. The useful part is that it remembers what you paid. Photograph a receipt and the lines come back structured, each one showing a crop of the row it came from and what that item cost last time, and where. Most of the work went into not saying so when it isn't sure. Two prices in different units are never compared, and comparison is on unit price, not the line total: buying 2kg instead of 1kg is not a price rise. iOS and Android.
maker here.
the thing that started this was a shared grocery list that was really a screenshot of a notes app, sent back and forth, always one version behind. every to-do app I tried was built for one person and had sharing added later, so the moment two people touched the same list it fell apart or turned into a paid team plan.
so Psst is built the other way round. a list is an invite. add the people it concerns and they see every change as it happens, with roles so the wrong edit cannot happen, comments on any item so decisions live next to the task, an activity feed, and presence so you can see who is on the list with you. all of that is in the free tier. it is not a crippled demo with the collaboration paywalled, because collaboration is the entire point of the app.
it works fully offline and syncs when you are back, which matters more than it sounds when you are standing in a supermarket with no signal.
being straight about where it is: it is early, and the review count reflects that. iOS, Android and web, no ads, no tracking, no selling data. I would rather hear that something is missing than have you be polite about it.
what I am most curious about: if you share lists with someone today, what breaks first?
the receipt-to-structured-line-items part is the actual product here, the shared list part is table stakes at this point. does the price memory match on the item name from the receipt text, or did you have to build some fuzzy matching for when the same product shows up worded differently between stores
curious about the $0.99 for 3 months pro offer. does that convert to paid better than a normal free trial? always wonder if a tiny paid step filters out people who'd never pay anyway
The price history is what makes this more interesting to me than a normal shared list.
I like the idea of keeping little decisions on the item itself instead of losing them in chat.
This is basically what my partner and I use WhatsApp for when we’re shopping.
Honestly the unit price comparison makes way more sense than comparing the total.
The receipt crop is a really nice touch I’d definitely want to see what it picked up.
