CLI - TOTP/2FA tool with fuzzy search - A script on top of timetrap, to type a number and change your current activity (emulating a Timeflip) - A simple view of % of time spent for each activity - A few scripts on Python, PHP or Go to automate stuff at work

Web - A site to ask people of their preferred time for a meeting, trying to find one working for all (quite difficult :) - https://eapl.mx/price/ Compare price and sizes/weights of 2 products to know which one is 'more' convenient - https://eapl.mx/twtxt/ A public view of my twtxt microblogging, and a single-user admin view - http://gemugami.com/time/ Get your browser's timezone

Not tools, but quite interesting - http://gemugami.com/hexclock/ An hexadecimal clock - http://gemugami.com/clock/ A decimal clock ('hours' from 0 to 1000) - http://gemugami.com/kcolc/ Time goes in reverse from 24h to 0 - http://gemugami.com/solar/ Shifts the time to be 7am at sunrise, based on your location - http://gemugami.com/holmes/ A scoring app for a board game
