About this app

Have you ever received your paycheck but weren't sure how much you could spend today?

Daydon is not a complicated ledger. It is a living expenses app that first subtracts savings, fixed costs, and major future expenses from your monthly income, then tells you "It is okay to spend up to this amount today" based on the remaining money.

■ Recommended Amount for Today

It divides your remaining living expenses by the number of remaining days to show you the amount you can safely spend today.

It is okay to go over a little. We automatically recalculate the remaining amount for you. We help you adjust your budget without pointing out budget failures.

■ Home Widget

You can check the amount you can spend today right on your home screen without even opening the app.

The small size displays only the amount and remaining days, while the large size shows the recommended amount for tomorrow and the amount spent today as well.

The widget changes immediately as you record your expenses.

■ Should I Buy It or Not — Calculate Before You Buy

If there is an item you are considering, just enter the name and price. We will immediately show you how much your recommended daily spending will change if you buy it now.

We do not tell you to buy it or not to. We will only show you the numbers; you make the decision yourself.

Items that are difficult to purchase immediately can be prepared in the safe over several months.

■ Postponing Spending

If you find it difficult to decide right away, put it on hold for a while. If you still think of it 30 days later, you can buy it then.

Items you decide not to buy accumulate as "money saved." We do not pressure you to hold back; instead, we gather and show you items you are glad you didn't buy.

■ Setting Aside Savings and Fixed Expenses

Exclude monthly expenses, such as installment savings, rent, and insurance premiums, from your living expenses in advance. This reduces the likelihood of mistaking money remaining in your account for living expenses.

Changes in the amount are reflected starting from that month, while past records are preserved. For items that have ended, such as an installment savings maturity, you can set them to "only until this month."

■ Preparing the Safe in Advance

Large lump sums like car tax, property tax, and family birthday gifts.

We will tell you how much you should transfer separately each month leading up to your target month. The amount transferred in advance will not be removed again in that month, so you won't falter even in months with large expenses.

■ Monthly Budget and Calendar

Your budget may vary each month. You can record this month's budget separately and view your spending flow and days spent without spending at a glance on the calendar.

You can also adjust the budget reference period to your desired date (such as payday or credit card payment date) instead of just the 1st.

■ Period Report

While in progress, it displays your pace relative to your budget, frequently used items, and a guide for the remaining period. Once the period ends, you can review the month with a settlement report.

Categories such as cafes, food, and transportation are automatically grouped simply by entering the expense name, eliminating the hassle of selecting classifications when entering data.

■ No-Spending Challenge

You can challenge yourself to go no-spending by setting a desired number of days. Choose the standard that suits you best from options such as complete no-spending, allowing essential expenses, or a daily spending limit.

Completed challenges are recorded.

■ Notifications That Come Only When You Need Them

Notifications are all turned off by default. Please enable only the items you want in the settings.

You can receive today's recommended spending amount in the morning, record reminders in the evening (only when there are no records for that day), reminders the evening before when savings or rent payments are due tomorrow, 30-day hold notifications, period settlement reports, and notifications for months with concentrated large expenses.

We do not send warning alerts on days when you exceed your budget. If there are multiple notifications at the same time, they are combined into a single message.

■ Data Backup

You can export and restore your data as a file in the settings. It can be transferred exactly as is even if you change devices.

■ Suitable for:

· Young professionals, office workers, and single-person households

· Those who have received their salary but are anxious about how much they can actually spend

· Those whose budgets are shaken by irregular expenses such as car tax and insurance premiums

· Those who find complex data entry burdensome but want to know their daily baseline

■ Personal Information

There is no login required. Data entered is stored only on the device and is not transmitted to a server. It is not linked to banks or credit cards. The app asks for the only permission from the user for notifications, and even then, it only asks when you first turn them on. If you do not turn on notifications, it asks for nothing.

It does not request sensitive permissions such as location, contacts, photos, or text messages.

Day Done is not an app that analyzes spending; it is an app that protects your money for today.

You saved today's money. Day Done.
A daily budget ledger that sets aside savings and fixed expenses first, telling you only the amount you can afford to spend today.
