Call for Laevo user study participants


With great pleasure I can finally announce the first public installer of Laevo, a project I started out working on as part of my master’s thesis, and am now continuing working on as part of my PhD. In short, it allows you to organize your work in new ways which Windows traditionally doesn’t offer you. In case you spend most time of the day working on your PC you might be interested in trying it out. The project has come a long way and is finally ready for the greater public, hence I am looking forward to your input on what you think about the system. You would help me out greatly by installing Laevo, trying it out for one to two weeks, and giving feedback on it afterwards. Please send me an email (sjeu at or simply contact me in case you are interested in participating.


You can download the latest version (v0.1.3) here. This is a more recent version than the one I linked to on twitter earlier this week. In case you already installed the previous version, simply uninstall the old version and install the new one. Your data and settings will be saved. To get you started I strongly advise you to quickly read through the manual so you know about the functionality offered.

    This does sound interesting in that it’s a calendar with highly enhanced functionality in which a lot of thought is being put, but sadly, unless it fully and seamlessly syncs with my Android phone’s calendar, this is absolutely useless to me…

    It’s definitely an interesting initiative, though. I’ll keep an eye on it.

      Naturally, eventually that’s (part of) the idea. Hence Alpha v0.1. ;p Unfortunately it’s a research project and I have to prioritize what to work on first. Synchronization isn’t that straight forward to implement and poses many new design questions. What would it mean to ‘seamlessly sync’, and is that even desirable? Therefore I am first releasing this version to collect initial impressions. Thank you for your interest!

    It sounded promising and I decided to give it a try, however I got it crashing after just 3 minutes of use. Is there anywhere you save a log which I can provide you? or should I just describe what happened that made the application crash?

      Yes, check the folder “C:\Users\username\Documents\Laevo”. There should be a “log.txt” file there. Please email this to me. Describing what happened is also really helpful, especially if the steps are reproducible. P.s. I just fixed a bug where you had a to-do item (the icons at the bottom) open (thus a yellow border), which you then dragged to an activity on the time line. This is now fixed:
