Sellf is very easy to use. It allows you to keep a list of clients in the pipeline. Everything on a single app, todo list, calendar, contact management and other features. Apple and android versions of the app is perfectly similar.

This is one of the best software for Customer Relationship Management that I ever tried! It's quick to learn how to use it, and it could sync totally all the features. There are no differences between Apple and Android version, I've tried both. It also increases the productivity, and I can also manage an entire team with monthly goals!

Easy sales tracking. The client managing is great and files management is best.
