The 50/30/20 rule, simply explained
50% needs, 30% wants, 20% savings: a simple rule to take back control of your budget.
Cash leaves no statement behind. Pennoway gives every note and coin a record, so your budget includes the money banks never see.
Cards keep a history for you. Cash does not. You withdraw 100 EUR on Monday, and by Thursday 15 EUR is left with no idea where the rest went. If a large part of your daily life is paid in notes and coins, you need a budget app for cash that makes logging faster than forgetting.
Cash is still everywhere: markets, taxis, small shops, tips, school contributions, the café. In Tunisia and much of the Maghreb it is the default for daily purchases, and many people in Europe and the Gulf use it on purpose to spend less. The problem is never the cash itself, it is the missing record. Without one, your monthly budget only shows your card, which may be half the picture.
Pennoway lets you keep several wallets side by side: cash, card, savings, or as many as you need. A simple routine works for most people:
The monthly wallet shows a daily “left to spend” figure that includes your cash, so you know whether today’s market trip fits the plan.
The envelope method is the classic cash budget: you divide your money into envelopes for groceries, transport and outings, and when an envelope is empty, spending in that category stops. It works, but carrying five envelopes is not practical.
You can reproduce the idea in Pennoway with one wallet per envelope and a simple transfer at the start of the month. For example, on a monthly 800 EUR cash budget:
Each time you log a purchase from one of these wallets, you see what remains in that envelope. Our step-by-step cash envelope system guide explains how to set the amounts and what to do when one envelope runs dry.
The hardest part of tracking cash is the moment of entry. You are holding change, a bag and maybe a child’s hand. With the AI assistant, you can type or dictate a short sentence like “8 dirhams bread and 25 dirhams fruit” and confirm the expenses it prepares. If you forget a purchase, the GPS module can remind you of the places you visited during the day, so you can fill the gap that evening.
After four weeks of honest logging, the numbers usually surprise people. A typical finding: daily coffees and snacks paid in cash total 90 TND a month, or more than 1,000 TND a year. The statistics screen shows the yearly cost of each habit, and the weekly comparison tells you whether this week was better or worse than the last.
You do not have to cut everything. Choose one habit, set a lower envelope for it, and keep the rest. Small, visible wins are what keep a cash budget alive.
Few people are 100 % cash. Pennoway puts all wallets in the same budget, so a card payment for rent and a cash payment for vegetables both count toward the month. Transfers between wallets are not counted as spending, which keeps your totals clean.

Pennoway is free, works without any bank connection and is available on Android as a direct APK download.
Withdraw a planned amount once a week, log every purchase right when you pay, and compare the app balance with the cash in your wallet every few days. A dedicated cash wallet in an app makes this take seconds instead of a notebook.
Yes, and that is exactly what cash needs, since banks never see what you pay in notes. In Pennoway you record withdrawals as transfers to a cash wallet, then log each purchase from that wallet.
Count your cash and use a balance adjustment to correct the wallet. Note the difference: if it keeps happening, you are probably forgetting a recurring small purchase, such as tips or snacks.
Yes. The principle of giving each category a fixed amount and stopping when it is empty works with paper or with an app. Digital envelopes simply remove the need to carry several envelopes around.
At the start of each month, Pennoway asks for your income and computes how much you can spend per day.
