GainUp compares
This week's prices and deals, per kilo or per litre, in stores near you.
You save
The cheapest plan, or the best store if you only want to go to one. Your savings are shown.
Everything you need to grab a bargain
Plans to choose from
Everything at the lowest price across several stores, or a single store, the best value for your list.
Every deal
"2nd at −50%", "1+1", "−30% for 3": every deal is turned into a real price per item.
Fake deals spotted
GainUp keeps a price history and warns you when a "deal" isn't really one.
Stores near you
Only the stores in your area count.
The whole family adds live
Send a link: everyone adds what's missing and ticks items off in store, and the list updates for everyone.
Told when the price drops
On every product, the price curve of the last 8 weeks and “Tell me if the price drops”, in the shops you choose. At most one notification every 2 days.
Your loyalty cards, even offline
Xtra, Lidl Plus, Intermarché…: the barcode shows at the till, even without a connection. The numbers stay on your phone.
Your list built around your shops' deals
GainUp puts each product where it's on offer this week, and sorts “In store” in aisle order.

An honest comparison, or no comparison
Comparing a 12-pack with one bottle, or organic with standard, skews everything. GainUp never does it.
