I like streaks when they get me to open the app. I don't like the tiny bargain I make with myself at 11:57: pick the easiest lesson, keep the numbe...

I keep seeing the gap between an edited note and a reviewed note. An edit says someone touched a sentence. A review says the whole page still match...

A record written two hours later often sounds cleaner, but loses the awkward part that actually mattered. For repeated work, the prompt should appe...

We tend to judge checklists by whether the steps are correct. I think the harder question is whether the checklist appears when attention is availa...

For repeat lookup notes, I would put the answer first and the explanation second. The reader is usually already in motion. They need the setting, p...
