Kubera is as simple as Excel or Google Sheets, but better for portfolio tracking.
On the surface, Excel (or Google sheets) seems like a pretty simple program without much of a learning curve. Just enter the data into rows and columns and you can look it over at any time. Google Sheets has also the advantage of sharing features so others can access the same information if you allow them to. But in order to make the best use of Excel or Google Sheets as a financial planner, you need to learn how to use formulas - from simple summing up to pretty complex ones if you want automatic updates.
Kubera also allows you to quickly enter information into a simple table but you don't have to learn formulas to get your totals and percentages. The rows can be connected to your online banks, brokerage accounts, crypto wallets to update the account balances and to various other price feeds to get the latest value of your stocks, crypto coins, homes, cars, domain names etc. You can keep notes and upload documents in context against every row. And finally Kubera has unique sharing features that's designed to ensure this information pass on safely to your beneficiary only if you’re inactive for a certain number of days and don’t respond to Kubera’s attempts to reach you.
