I have been using Todo for almost a month. I’m using it to keep track on the things I need to get done at work. I have to submit a TPS report every Friday, and Todo makes that simple. All I have to do is select a date range from the in-app calendar, select the items that were completed during that range, and then copy/paste them. Perfect. The only thing that would make it better is if it changed active voice to passive voice for me. e.g. “Add new SSL termination to load balancer” -> “Added new SSL termination to load balancer”. I use Dropbox to sync my tasks between my devices. Unfortunately, Todo does not create its data store in the “/Apps/“ directory within Dropbox and there is a crashing bug in the current version when trying to change the Dropbox location. Support has confirmed the bug and said a new version has been submitted to Apple. So I can hopefully fix that small quibble soon. I also had to contact support to figure out how to get back to my list of uncompleted tasks after selecting a date range. Turns out I was overlooking a simple “x” to clear the filter. Support was quick, patient, and helpful though. I’m deducting one star for the crash and non-standard Dropbox storage location. However, Dropbox support wouldn’t even be an issue for me if it supported the new iCloud Drive protocol. But I understand that is very new and will take them at least some time to catch up. Update 2015-04-15: this thing has flat out stopped launching. It doesn’t log anything to the system logs. It just bounces the icon a few times, stops, and then right clicking the icon shows the application is not responding. So, basically, it’s useless. I’m going to look for something else. This sort of application is not complicated; I don’t know how it is this messed up.
