Battery Sensei
Be Zen about your Meetings
What this is
A macOS menu bar utility that tracks battery health and charging limits, and warns you if your Mac's battery won't last through an upcoming calendar meeting.
Our one-line summary — not the founder’s tagline.
- How it works
- A macOS menu bar app that watches your calendar and warns you if the battery won't last through an upcoming meeting, alongside custom low-battery alerts, charge limits, and stop-when-hot charging.
- What's different
- Ties battery warnings to your actual calendar rather than a flat percentage threshold.
- Best for
- Mac users who want to avoid dying mid-meeting and manage battery health passively.

Where it shows up
Every group here is a page of its own — each one checked daily.
The numbersIs it still shipping, is it overpriced, where did it land — and what the price is built from.
League price & chart
No money. No seat. It goes on your record — and in 28 days reality settles it.
Calls are closed while we rebuild accounts. You can still read every one of them.
Productivity. Launched 13d ago on Product Hunt, picking up 16 votes. Today, it's been quiet for 10 days and the price has started to bleed.
Already bleeding a little every day, and it accelerates the longer it stays quiet.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 16 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
En eski 1 hareket bu listede yok — toplam 13 olay var. 1 quiet day in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
