Most consumer tech focuses on performance: faster, stronger, bigger numbers.
But some of the best products I’ve used recently focus on something else entirely — feedback.
Take brushing your teeth.
Everyone does it. Almost no one knows if they’re doing it well.
That’s what made me curious about smart toothbrushes in the first place.
The BrushO AI toothbrush doesn’t just clean — it teaches.
After brushing, the app shows:
how evenly you brushed
whether you used too much pressure
and a simple score that’s easy to track over time
No charts overload. No complicated setup.
Just information you can actually use.
What I like most is that it doesn’t try to change your routine.
You brush the same way — it just quietly helps you improve.
Over a few weeks, I noticed:
less gum irritation
more even brushing coverage
fewer rushed sessions
Another smart detail: instead of pushing subscriptions, it rewards consistency.
Keep brushing, earn points, and eventually get free replacement brush heads.
It feels fair — and way less annoying than reminders to “buy more.”
Good tech doesn’t need to shout.
Sometimes, it just needs to show you what you’re missing.
