Multiple exchanges
Holdings spread across different markets and brokers, reconciled into one consistent view.
A portfolio tracker for the holdings you enter on every exchange you use. It converts them into a single currency you choose, and keeps the dividend and tax detail that most trackers leave out.
Holdings spread across different markets and brokers, reconciled into one consistent view.
Every position converted to your base currency, so the total actually means something.
Payment history, yield on cost, and what is scheduled to arrive next.
Cost basis and realised gains kept alongside each position, not buried in an export.
Fully translated interface rather than an English app with labels swapped out.
Your portfolio lives on your device. No account to create. Crash reports carry no holdings, and full diagnostic logs only if you allow them.
Free to use, with a paid tier for larger portfolios.
OneSum is free up to a set number of holdings — enough for most portfolios, and not a trial that expires. Beyond that limit, a yearly subscription unlocks unlimited holdings.
Subscription is the only way OneSum makes money. No advertising, no selling or sharing your data, no commission from any broker, exchange, or fund.
The limit and the price will be published here before the paid tier begins. Until then, everything is free.
OneSum is a read-only software product. It shows you what you already own. It never moves anything.
OneSum does not connect to your broker. You enter your holdings yourself; the app only fetches market prices, dividends and exchange rates.
Figures shown in the app are for information only. They may be delayed or incomplete — always check your broker’s own statements before acting on anything you see here.
Questions, bug reports, or feature requests — email is the fastest way to reach me.
I read every message and reply personally, usually within a couple of days.
