Chronos a Drag-and-Drop Scheduler

I built this because every scheduler I tried starts you on the calendar. I always found the easiest way to plan is to have a list of tasks and then put them on the schedule. Chronos is built around that flow. Tasks live in a panel on the right, you drag them onto the calendar on the left, and done.

I'm a high school student and built this primarily for my own scheduling. Sharing it as I think it's a better way to schedule. I wrote it with AI assistance just to speed up the process.

A few things that might be interesting technically: - The entire app is a single HTML file with no frameworks, no build step, no backend. You can download it and open it in a browser with no setup. - Save/load works via a base64 JSON blob you copy and paste to load your schedule. - There's a Telegram bot assistant that reads the save code and sends you reminders before events. Keeping it free to run was a challenge. - I think all the functions I ever needed are there. You can schedule the normal way ofcourse as well.

Known issues: the PDF export and iCal integration are kinda bad. If you run into problems with those I'd genuinely like to know. Built this around my own needs so it might have blind spots once again. Would appreciate any feedback on the UX, thank you!!
