I am launching the Expensinator - an expenses tracking web app. Here are the core features:
You can have multiple accounts which can be imported or exported.
Each account can hold multiple receipts, they could be categorized for better understanding of the data
The data in the account can be analyzed in the chart section
The data is stored on your browser local storage called IndexedDB which can hold multiple gigabytes of data.
The bigger bonus of using the web app is that you never need to create an account and share your email or any other personal data, you can start to use it straight away
