Hello world!
Announcing Costpad!
It is a purchases log service that I wanted to develop as a “supermarket” companion, but it can be used for any kind of purchases.
The basic philosophy behind it is: “By logging your purchases, you keep a track of your expenditures and at the same time you inform the community of the price of the products you bought”.
The site is in alpha stage, but in a minimum useful condition (my girlfriend and I use it daily).
As all community-based sites, the “chicken-and-egg” problem exists: The site’s value increases when users use it, but users use it only after it has gained enough value… For now, the database is small and contains only products/shops found near me, in Greece ;), but I hope I have made it easy enough to add more content.
Features:
- Submit/Log your purchases
- View your basic monthly/overall spending statistics
- Separate accounts
- Shop map location
- View product’s latest market price
- View product’s cheapest vendor
- Smart shopping lists (automatically remove/decrease items when bought)
- Finger friendly for touchscreen devices
To come:
- “Downloading” a shopping list via SMS to your mobile (for low-tech, no data-plan users)
- Automatically “solve” the shopping list “equation” and propose cheapest location to buy the items
- Coupling with Barcorama is on its way naturally… The vision: “Return home from the supermarket and use your pda to quickly+accurately log the purchases…”
- Voting system to filter out the bad/inaccurate information
- Automatic logging of purchases (e.g. using Paypal receipt emails)
- Database security: encryption of user private entries
- Own data export/import
- Bug fixes!
I’m not a web developer so please, bear with me…
have fun
