About this app

GELD VERSTEHEN is your household budget book for everyone who wants to keep track of their spending without spending hours maintaining numbers. Developed from the coaching practice of financial coach Per Schippl.

FIXED COSTS AND FLEXIBLE COSTS SEPARATELY AT A GLANCE
Rent, insurance, subscriptions: you enter your fixed costs once – including those that are only debited from your account annually or quarterly. Your daily expenses, the flexible costs, are recorded in seconds. The dashboard shows you your monthly balance at any time.

CLEAR INSTEAD OF CLUTTERED
No frills, no flood of charts. One glance is enough to see how much money you have left this month. If you know your costs, you save along the way – without going without and without drastic measures.

PLAN AHEAD AND LOOK BACK
You can switch between months, make entries retroactively and plan your income and expenses for the coming months in advance. Even with a fluctuating income, you keep track of the whole year.

KEEP AND SHARE MULTIPLE BUDGET BOOKS
Separate your finances into several budget books – for example "Personal", "Family" or "Household". You can share selected budget books with your partner or family and manage shared costs together.

KNOWLEDGE SECTION INCLUDED
Strategies and content from coaching practice help you understand your money better and hold on to it.

START WITHOUT REGISTRATION
No sign-up, no bank account to connect. Open the app, enter your first numbers, done.

This app is brilliant. Nice & easy to use to keep all your finances in check, plus it's free. This app to me is the best I've tried & I've tried far to many budgeting apps, many paid for.

What’s new

OnePeek is now called GELD VERSTEHEN.

New name, same app. Your data, your budget books and your subscription stay exactly as they are – there is nothing you need to do.

Why the name? GELD VERSTEHEN is the podcast and the brand of financial coach Per Schippl, out of whose coaching practice this app grew. From now on both are called the same, so it is easier to find.

On the home screen the name may appear shortened, because it is longer than the old one. That is normal.
