Our Ledger - Family Budget

Our Ledger is a budget book the whole family shares. Record daily spending in seconds, and everyone in the family sees the same books right away.

■ One ledger for the family Invite your family with a code or link. Whatever anyone records shows up for everyone instantly.

■ Record in 10 seconds Type the amount on the keypad and pick a category. Save your usual shops per category and fill them in with one tap. Attach receipt photos, too.

■ Budgets and alerts Set a monthly budget and budgets per category. See how much is used and the projection for the period, with colors and icons when you are about to overspend.

■ Clear reports Category breakdown, daily spending, per-member totals and 12-month trends, as charts or tables. Export to CSV.

■ Settle up, too Mark spending as shared or personal and set split rules: the app works out who owes whom. Families that don't need it can turn it off and keep things simple.

■ Four languages Japanese, Chinese, Vietnamese and English. Each family member uses their own language on the same books.

■ Built to be safe - No bank or credit card logins are stored - Data is encrypted and stored in the AWS Tokyo region - The activity log shows who changed what and when - Delete your account at any time; no ads and no selling data to third parties

Besides the iPhone app, the same books are available on the web at web.uchinokakei.com.
