An Android app that helps you track your spending and savings.

Note: This is a passion project that's developed for personal use. It is not intended to be released as a commercial product (yet).

Must-Haves:

• Add a new spend/income entry
  • Income or expenditure
  • Date
  • Amount
  • Category (defaults to uncategorised)
  • Image (optional)
    • From gallery or connect to phone camera
  • Description (optional)
• Edit an existing spend/income entry
  • Any of the fields
  • Upon changing the image, the old image will be discarded (unless it has been backed up, and the user restores the backup)
• Delete an existing spend/income entry
• View summary of spending/income
  • Different periods
    • By day
    • By month
    • By year
  • Pie chart
• Back up
  • Local storage (automatic, offline)
  • Google Drive (requires internet connection, can change backup location/file name)
  • "Back up now" to force an immediate local and Google Drive save (if connected to a Google Drive account)
  • "Sync from Google Drive" to pull Google Drive data, saves to local storage as well (can't undo!)

Nice-to-Haves:

• Different types of currency
  • Will be an app-wide change. All past entries will be updated with the new currency symbol.
  • User can provide an exchange rate to update past entries. Default rate is 1 (unchanged).
    • Some way to undo/confirm the change.
• More user options
  • Auto entries (e.g. automatically add salary entry on the 1st of the month)
    • Shortcut buttons (e.g. button to automatically add a $5 lunch expenditure)
  • Customise categories
    • Icon from provided list or gallery image
      • Notify if icon from provided list is being used as the icon for another category.
    • Category names must be unique
    • Able to have sub-categories (e.g. food -> snacks)
    • If a category is deleted, all past entries with that category is converted to "uncategorised"
      • "uncategorised" cannot be deleted, but can be renamed.
  • Default default entry options
  • Change back up options
    • Auto back up (will require internet connection to perform auto back up to Google Drive)
    • Back up only when button is clicked
  • Export data as .xml or excel spreadsheet etc.
• Payment methods for backing up to Google Drive
  • Only if the app is tailored to become a commercial product.
• Import some existing ML library to parse photos of receipts and auto-populate spend entries

• Define requirements
