I must admit, if I had a newer iPad I would rush and get this Clockwork for Harvest app. It just looks cool! It’s an iPad app (free at the moment) for iPad that let’s you interact with Harvest (for time tracking).
As a person who makes a living as a UI designer (in Phoenix, AZ) I can see some fairly significant issues with this design, but it’s cool and I like how different it looks. It looks like a nicely designed form from the 60s made with letterpress.
If you only track your time to a couple of projects, this would be a sweet way to track your time every day.
