For those having trouble keeping track of all their commitments and tasks on a daily basis, look to a personal information manager app like Astonsoft's Essential PIM Pro. The app organizes appointments, notes, to-do lists, contacts and other important data together in one place. Essential PIM Pro can also house email and various passwords, plus synchronize that data with other devices (Android, iOS) as well as cloud services (Google, iCloud, etc.). Data is encrypted with an AES 256-bit key and the cloud service synchronization is protected via SSL.
