Volt tracks every battery-powered device in your house and estimates when it's due for fresh batteries, so nothing dies on you unexpectedly.

Purchases

Volt Pro is a one-time purchase ($2.99) that unlocks unlimited devices (the free version supports up to 3), spare-battery inventory tracking by size, and low-battery alerts. The free app fully tracks up to 3 devices on its own, forever.

Frequently asked questions

How do I restore my Pro purchase?

Open the app, go to Settings, and tap "Restore Purchases." Make sure you are signed in with the same Apple ID you used to buy Volt Pro.

How is the charge level calculated?

You tell Volt how many days you expect a set of batteries to last in a device. Volt compares that to the days since you last replaced the batteries to estimate how charged the device is.

How do I mark batteries as replaced?

Open the device in the list and tap "Replaced" — this resets its charge estimate to full as of today.

Is my data private?

Yes. Everything Volt tracks stays on your device. Volt has no network access and no third-party advertising or tracking SDKs. See our Privacy Policy.

How many devices can I add for free?

Up to 3 devices at no cost. Volt Pro removes that limit.
