Finance Apps Compared: What Each Category Is Actually Built For

There is a reason comparison lists for finance apps rarely help: they line up products that answer different questions. It is about as useful as comparing an estate car, a racing bike and a camper van by number of seats.

This guide takes a different route. It sorts the field by category, names the blind spot of each — and helps you settle the question you actually want answered before you install anything.

First the question, then the app

Four questions cover nearly every use case. They do not exclude each other, but one of them is the pressing one for you right now:

1. “How much is in my accounts?” — liquidity, payments, day-to-day.
2. “Where is my money going?” — spending behaviour, fixed costs, subscriptions.
3. “How is my portfolio doing?” — returns, allocation, individual holdings.
4. “What do I own in total — and which way is it moving?” — net worth across all asset classes, debts included.

If you have question 4 and buy an app built for question 1, you were not badly advised. You picked the wrong category.

The five categories

This overview deliberately describes categories and not individual products. Feature sets change constantly; a product comparison that is accurate today is stale in six months and misleading in twelve. What stays stable is how an app is built — and that determines what it can show you at all.

Banking and multibanking

Principle: accounts at several banks are connected, transactions merged, balances displayed.

Strength: unbeatable for day-to-day life. One look, every account, current state.

Blind spot: whatever produces no transactions does not exist. The flat is missing, the mortgage appears only as a monthly payment and never as remaining debt. The result is a liquidity overview that is easily mistaken for a wealth overview.

Budgeting

Principle: spending is categorised, budgets are set per category and monitored.

Strength: the best category for genuinely understanding and changing how you spend.

Blind spot: the asset side — and the upkeep, which is where most implementations quietly die after a few weeks. Why that happens and what the alternative looks like: budgeting without category upkeep.

Portfolio tracker

Principle: securities positions are recorded and their performance followed.

Strength: depth on the portfolio — returns, weighting, individual holdings.

Blind spot: everything else. A portfolio is one part of your wealth, and rarely the largest. What the category does — and why two apps can show different returns for the same portfolio: Portfolio tracker.

Spreadsheet

Principle: self-built, usually grown over time.

Strength: maximum freedom. Anyone who keeps a spreadsheet going for years often has the most honest picture of all.

Blind spot: its half-life. Spreadsheets need you. After two skipped months the numbers no longer hold, and getting back in costs more resolve than keeping it running ever would have. When the spreadsheet stays the better choice and when it does not: Spreadsheet or app?

Net worth app

Principle: both sides of the balance sheet are represented — assets and liabilities — including items that produce no transactions.

Strength: the only category that answers question 4 completely, and it makes the movement over time visible.

Blind spot: less depth on the individual transaction than a dedicated budgeting app. What matters here: net worth trackers compared.

The costliest misconception: transactions are not wealth

If you take one thing from this guide, take this: an app can only show what its data source contains.

Connect accounts and you get transactions. From transactions you can derive spending, fixed costs and subscriptions beautifully. You cannot derive a net worth from them, because the largest items in a typical household produce no transactions at all: the property, the car, the remaining mortgage.

That is precisely why many apps show a sum across your accounts and call it “wealth”. The arithmetic is right — the label is not.

If you want to know where you stand, work it out once yourself:

Bank connections: useful, not a seal of quality

Automatic syncing is convenient, and for daily balances it is the right thing. For tracking wealth it is not strictly necessary — there, the monthly figure is what counts, not the hourly one.

This is more than a question of effort. A connection means a third party has standing read access to your transactions. For many people that is a fair trade. For others, a monthly export from online banking is the route with fewer dependencies — and for the wealth question it gives the same answer. The full trade-off: finance apps without a bank connection.

Three things worth checking in any category:

• Where does the data sit? Server location and jurisdiction are in the privacy policy, not the store listing.
• What access does the app request? Read access to transactions is a different thing from permission to initiate payments.
• Can you get back out? Building wealth takes decades; providers rarely last that long. Without an export, your history is only on loan to you.

A note if you are not German

This site is written for people living in Germany, and one point deserves spelling out for anyone whose financial life is not entirely local: aggregator coverage is not evenly distributed. Connection-based apps are strongest with German institutions and noticeably thinner abroad. If a meaningful share of your money sits in accounts outside Germany, a connection-first app may simply be blind to part of it — and the completeness you were buying is exactly what you do not get.

In that situation, an app that also accepts file imports and manually maintained items will usually give you the more truthful picture, even though it asks a little more of you each month.

What sum is built for — and what it is not

We are building sum in the net worth category. Concretely:

What sum is for: your net worth across every asset class — accounts, portfolios, property and valuables as pure value items, loans and outstanding balances on the liabilities side — with history and breakdown. On top of that: automatically categorised spending, detected fixed costs and subscriptions, a flexible budget and goals with a rate and a forecast.

What sum is not for: sum is not a bank and not a broker. You cannot make transfers, set up standing orders or trade with it — that is a deliberate decision, not a missing feature. If you are looking for an app to pay with, the banking category serves you better.

And where sum stands today: your transactions come in via CSV import from online banking; the automatic bank connection (PSD2) is in the works. That is one more manual step per month today — and at the same time the route where no third party sees your transactions on an ongoing basis.

Frequently asked questions

Which finance app is the best?

There is no general answer, because the categories answer different questions. Decide first what you want to know — account balance, spending behaviour, portfolio performance or total wealth — and pick the category from there. Within a category, the differences are usually smaller than between categories.

What is the difference between multibanking and a net worth app?

Multibanking pulls accounts and their transactions together and answers questions about balances and payments. A net worth app answers what you own in total — including items with no transactions, such as property and valuables, and minus your debts.

Do I need an app with an automatic bank connection?

For daily balances yes, for tracking wealth not necessarily. If you update your net worth once a month, a CSV import does the same job — and no third party gets standing read access to your transactions.

I have accounts outside Germany. Does that change the answer?

Often yes. Aggregator coverage is strongest for German banks and thinner abroad, so a connection-first app may simply not see part of your money. If a meaningful share of your accounts sits outside Germany, an app that also accepts file imports and manual items will give you a more complete picture.
