Sumio: Net Worth Tracker screenshots
Most people who hold a few investments end up with their financial picture split across a brokerage login, a crypto exchange and a spreadsheet that was accurate six months ago. Sumio is built to close that gap. It is a free net worth and portfolio tracker from the developer Fiduciary, and its promise is a single place where assets, debts and market positions add up to one number you can actually watch.
The app has been on Google Play since December 2021 and sits at a 3.8 average from 79 ratings, with more than 10,000 installs. That is a modest audience rather than a mass-market one, which fits the subject matter: this is a tool for people who already keep track of what they own and want the arithmetic done for them.
Sumio is free to install and carries no advertising, with a premium subscription behind the fuller feature set. That combination tells you something about the developer's intended audience straight away. Rather than selling attention to advertisers, the app is pitched at users who are willing to pay for a financial tool once it proves useful to them.
One number that updates itself
The core of the app is automatic calculation. Sumio derives net worth, total assets and total liabilities from whatever you enter, so you are not maintaining formulas by hand or reconciling totals after every purchase. For anyone who has kept a net worth spreadsheet, that alone is the main draw: the figures refresh as the underlying holdings change rather than when you remember to update them.
Prices for stocks, ETFs, crypto and metals update on their own. The developer also describes an AI assistant that generates summaries and insights for stock and fund portfolios, which is the kind of feature worth treating as a starting point for your own thinking rather than an answer in itself. What I find more immediately useful is the gains and losses view, which shows how market value has moved over time instead of only where things stand today.
Allocation charts round out the picture by showing how your assets and liabilities are distributed. That is the part of tracking that tends to get neglected, because a total can look healthy while most of it sits in one holding. Seeing the split laid out is what turns a net worth figure into something you can act on.
Stocks, crypto and everything else in one ledger
A watchlist follows holdings on American and international markets, updating live and alerting you when values shift. The notifications are the feature I would expect to matter most in daily use, since they mean you do not have to open the app to notice that something has shifted.
The tracker is not limited to market positions. You can record other assets and debts alongside them, and organize both with custom categories and indicators that carry their own colors and descriptions. The summary screen can be personalized with the indicators, categories and individual holdings you care about, which matters more than it sounds: a net worth app is only useful if the first screen shows the numbers you personally check.
Multi-currency support covers over 100 world currencies with automatic conversion into your default currency, and exchange rates are kept current. For anyone holding accounts, property or income in more than one country, that removes a recurring manual step. It is also the feature that makes the app plausible for people whose finances are not neatly contained in a single banking system.
Looking forward, not just backward
Projection models let you forecast how your net worth might evolve, which shifts the app from a record of the past into something closer to a planning tool. The value here depends on how much you trust the assumptions behind any projection, but as a way to compare scenarios, it is a reasonable addition to a tracker that otherwise only reports.
The developer's AI integration is presented as a way to turn market data into insights, and the assistant produces written summaries of stock and fund portfolios. I would treat both the projections and the generated commentary as prompts for your own judgment. They are described as decision support, not as advice, and the distinction is worth keeping in mind.
Between the two, the app covers both directions of the same question: where your money stands now, and where it is heading if nothing changes. That combination is what separates a net worth tracker from a plain account aggregator.
Getting your holdings in
Setup is more involved than installing and signing in, because a tracker is only as good as the positions you feed it. Sumio supports importing stock and fund purchases from an XLSX file, which is the quickest route if your brokerage or fund provider lets you export a transaction history. Anyone with a long investing record will appreciate not typing each purchase by hand.
For everything else, holdings are entered and organized within the app, using the custom categories and indicators described above. The developer's stated approach is that you build the structure yourself, which gives you control over how assets and debts are grouped but also means the initial setup reflects the effort you put into it.
There is a security lock using a passcode, Face ID or Touch ID, so the app can be protected on a shared or unlocked device. The developer also mentions exporting your data, which is how holdings stay consistent if you use more than one phone or tablet.
Sumio is free to install and shows no ads, and the developer states that the business model rests on a premium subscription, which covers unlimited asset tracking, market data access and features such as enhanced security and backup.
Who gets the most from it
Sumio fits investors who hold a mix of things. If your money sits in stocks, funds, crypto and precious metals, and possibly across more than one currency, the app's automatic market data, allocation charts and currency conversion are doing real work for you. The more scattered your holdings, the more a single consolidated number is worth.
It also suits people who think in terms of net worth rather than monthly budgeting. Sumio tracks assets and liabilities and calculates the difference; that is a different job from categorizing spending, and the app is built for the first one. Anyone whose main question is where last month's salary went would be looking at the wrong tool.
The 3.8 average from 79 ratings suggests a small, mixed audience rather than unanimous enthusiasm, which is typical for finance apps where expectations vary widely. The absence of ads and the subscription model point to a developer aiming at users who want a paid product rather than a free one supported by advertising. If you are comfortable paying for financial software and want your portfolio and net worth in one place, Sumio is built for exactly that.
A tracker for people who already invest
Sumio does one job and does it without much decoration: it collects your assets, debts and market positions, values them, and shows you the total. The automatic net worth calculation, allocation charts, gains and losses history and multi-currency handling are the reasons to consider it, and the projection models and portfolio summaries add a forward-looking layer on top.
The 3.8 rating from a modest user base is worth weighing if you like to see a long track record of reviews before committing.
My recommendation is for investors who already know what they own and want the totals, charts and currency conversions handled automatically, and who are open to paying for a subscription once the free install proves useful. If that describes how you manage your money, Sumio is worth trying.
The short verdict
A focused net worth and portfolio tracker for investors who want their holdings, debts and currencies consolidated automatically.
