  • I've been using this web app since the beginning of 2018 and it has helped me immensely. I love being able to search my training logs for details I wrote down six months ago that are now a little blurry. I love being able to see graphs of the hours I've put in, with their different labels and categories all nicely laid out for me.

    The dashboard is organised and motivates me to go train (when you don't train that week/month it puts a little sad face instead of the number of hours and that sad face always gets me off my ass.)

    Also, as a developer myself, I really appreciate and recognise the efforts of the creator to keep the site constantly updated and respond to bug reports in a timely manner. I have gotten a response within 24 hours every time I have reported a bug or requested a feature! Hats off.
