I am looking for client management software, for example someone has 100 clients, to some of them need to send email, to someone need to pay a visit, someone call back after few days for regualar follow up, and other client activity.
Preferbale to have available on both windows and android app to both have sync and send reminders on phone/mails.

I was looking for some like Wonderlist, Asana, they are free also.
Wonduerlist i found good and availableon both window and andorid.

Anybody has used another one with good success/interface?
Just wanted to know what else free software/apps available for this?
