About this app

Boss Notebook is an ultra-lightweight work record app designed for small business owners and sole proprietors.

You can organize client notes, on-site photos, requests, outstanding receivables, and scheduled payments all in one place. It is designed to be lightweight like complex ERP systems, yet not as cluttered as a simple memo app.

You can start immediately without signing up and record information quickly as soon as you open the app. We prioritized a workflow that allows for one-handed use whether on-site, in a vehicle, at a store, in a warehouse, or while on the go.
