About Amply
Amply is a battery app for Macs with Apple silicon. It uses the charge limit Apple added in macOS 26.4 and turns it on and off for you. There's no helper tool and no admin password, and it never writes to the chip that runs charging.
We wanted every state to come with a plain sentence. At the limit it reads "Your Mac runs on the charger and the battery rests." If the battery charges past your limit (or someone switches the limit off), you get a notification and 3 likely causes.
A few more things it does:
- Tracks battery health over 90 days, a year or since install, and exports a 1-page PDF.
- Tells you whether the charger you plugged in is enough for this Mac.
- Shows time left in words, such as enough for a 3-hour meeting.
- Charges to 100% once for a long day out, then turns the limit back on.
It comes in English, Spanish, German, French and Japanese. The trial is free for 14 days with every feature (no card needed). After that it's $9.50 once (50% off $19), and 1 key covers 3 Macs.
