Description by Dmitry Petrushin Written by the developer, not by AppBrain. Click to read.
Clients app — amazingly simple and beautiful app to comfortably and effortlessly store and operate your client data.

Universal solution
It doesn't matter if you are self employed or part of a big corporation, Clients app will organize client communication in a completely new way.

Benefits
Clients app provide you new ways to interact with your clients — your physical presence at the desk is no longer required, as the same tasks can now be performed remotely, wherever you may find yourself — external meetings, on the road, at home. Make notes, import contacts, add reminders, send emails and SMS, call your customers from Clients app.

The perfection lies in simplicity
Unlike your typical CRM, while developing Clients, we preferred to keep it clean from a variety of functions, the effectiveness of which was questionable, in favor of keeping it simple yet efficient. And at the same time, based on your feedback, in the coming months we will develop add-ons to extend the app functionality even further without compromising its usability. Stay tuned!
