A few weeks ago I said "I should open source it some day" in Reddit comment here. They told me to do it. So I did. Here's how it's going.

When I opened Fleche, “1 in 7 means about once a week, never on the same day” left me unsure whether consecutive days are possible or a cooldown prevents them. Spell that out beside the example: it matters much more for watering plants than surprise push-ups. Showing a sample week would also help someone understand their rules before waiting for tomorrow’s list. I make ThreadFox. I went through Fleche as a first-time visitor and wrote up what I hit; the full check is free: https://threadfox.vip/p/fleche Does a skipped task carry forward, or does tomorrow get a fresh roll?

Thanks for the feedback, i'll have a look :) The "skipped task" just stays open in your todo list until you mark it as done. If you set the rule as "stackable", it can spawn multiple times. If not, it won't spawn again until the opened task is done.
