Know what you can spend today. Before you spend it.
JarSlice splits every paycheck into jars (needs, wants and savings), then
tells you one number each morning: how much is safe to spend today and still
finish the month on plan. No bank login. No account. No subscription. Your
numbers never leave your phone.
-------------------------------------------
YOUR DAY AT A GLANCE
-------------------------------------------
• Safe to spend today, worked out from what's left and the days to payday
• Month pace: on track, ahead, or over, with an even-pace marker
• Living Jars: each jar is a glass jar whose level drains as you spend
• A daily logging streak and an optional 8 pm check-in
• Saved so far, and your savings goal with the month you'll reach it
-------------------------------------------
PICK A PLAN THAT FITS YOU
-------------------------------------------
• 50/30/20: needs, wants, savings and debt payoff. The most widely
recommended budgeting rule, and the easiest place to start.
• 6 Jars: the classic money-jar system. Essentials, emergency fund,
investing, generosity, fun and personal growth.
• 5 Jars · Faith: tithe and give first, then invest, save and live.
• Custom: build your own jars for debt, holidays, kids, pets, anything.

HOW IT WORKS
-------------------------------------------
1. Payday: add your paycheck and watch it split into jars.
2. Spend: tap + and log it in seconds. JarSlice suggests the jar from
your past entries.
3. Overspend one jar? JarSlice shows exactly which jars covered it.
4. Close the month: review planned vs spent, then start fresh.
It works like cash stuffing or the envelope method, without the cash.
