"As a bit of a twitter fan, I like the "cool" factor of logging time via twitter."
"Email, Twitter and SMS messages, mobile or desktop browsers, or even RSS feeds. The site is geared toward those tracking personal or group time spent on particular clients, with a tag-based tracking system and all the graphs and chart-y goodness you'd expect out of a data-rich site."
"Tempo is a simple and flexible, but one of its more compelling features is the ability it gives you to enter your time away from your desktop web browser via mobile phone, SMS, email or Twitter. And after you're done you can use Tempo to create a Blinksale invoice in no time at all. We think this is pretty cool."
"I've tested pretty much all of the web time tracking apps and Tempo is by far the best."
"I'd say it had everything I would need as a freelancer. As it is its well on the way to being one of my favorite applications."
"I've been using Tempo to track my hours with my first consulting job, and it's already saved my ****. When there was a typo on my Word time card I emailed PDF's of the reports from Tempo to prove it!"
"A really simple and effective take on time recording / management based on twitter. They have done a very good implementation of building an application which leverages the easy and simplicity of twitter."
"...I am finding Keep Tempo easy and convenient to use... I was using another popular product for a month, but the reporting features are much better with Tempo, and the pricing structure is much better."
"Thanks for a fantastic timesheet system - it is the first time sheet system I have ever used that makes me want to fill in my timesheet every day... and I used to hate timesheets!"
"In addition to offering a large number of reports and graphs to help you track what's going on with your time and tags, Tempo also gives you RSS feeds (so managers can monitor without even firing up the site) and the ability to invite free accounts to add time to your paid plan."
