croat.dev — Kvitko and Modulo
croat.dev
Behind croat.dev is one developer in Zagreb. I build apps for myself first, for things I actually need, and publish them once they're good enough to be useful to others.
Kvitko is made for Croatian receipts, stores and payment slips: instead of copying receipts into a spreadsheet, you take a photo and see where your money goes. Modulo is for furniture makers and anyone who builds their own furniture: one project gives you the drawings, the cutting list and the assembly order. Receipts and projects are saved on your device, and nothing is shared until you turn it on.
Kvitko
Android · beta · Croatian and English
An app for store receipts, payment slips and household spending. Receipts are read on the phone, without being sent to a server.
-
Scanning receipts
A photo, an image from the gallery or a PDF. Kvitko reads the store, date and items, and you check them before saving.
-
Spending and budget
Spending by category for the month or the year, and what is left of the monthly budget.
-
Prices at stores
For the products you buy, you see their prices at other stores, from the chains' price lists.
-
Payment slips and bills
Kvitko reads a payment slip from its HUB-3 barcode, so utility bills count as spending too.
-
Household
Receipts are shared with the household without user accounts, encrypted with a key only its members hold.
-
Company receipts
A company's R1 receipts are kept apart from personal spending.
Modulo
