Thought I would mention four apps for Mac and iOS devices I started using recently. So far they are working well.
I absolutely hate Mail on Mac PCs. Everytime I get a new Mac I try it again and about sixty days later I find an alternative. (Mail works fine on iPad and iPhone.) My latest alternative is MailTab. It is a small app that appears in the upper icon tray (next to the Dropbox icon below second from left). If you use Gmail, MailTab is viable alternative to Mail with near full functionality. Also, MailTab has a very nice design that Google should copy.
I am addicted to calendar apps. I have always disliked the calendar app for Mac partly because the icon is so ugly. I used Agenda but it did nothing to address any of my issues, although the design is first class. Now I am using Tempo. This is a terrific app with a beautiful design but what makes it valuable is the contextual information it provides for an event: email address for attendees, profile of each attendee (LinkedIn, etc.) map of location for event, website of company where event is and more. It only works on iPhone but that is where I need the contextual information. Screen shot below.
Eventbrite is an app for event tickets. No big deal. What is very nice is the event calendar of all events in your city using Eventbrite. For Miami it is one of the best event calendars I have seen. If you are a big networker, the event calendar alone is worthwhile.
Paybyphone is a great app if you park on the street in Miami or Coral Gables. Nice design and simple to use. Only way I see to make it better is if it told you where the empty parking spaces were. Also works in many other U.S. and Canadian cities and at certain universities including the University of Miami.
Most of these apps are also available on Android and all are free.
