How much does Sentry Pro cost

Sentry Pro offers two subscription options, both of which come with a free 7-day trial period, plus an one time lifetime purchase:

• Monthly subscription: $5.99/month
• Annual subscription: $49.99/year (saving over $22 compared to monthly)
• Lifetime purchase: $223.32 $133.99 (one-time payment that permanently unlocks all Pro features) - Currently 40% off as a limited-time promotion!

The prices listed above are for US customers. Prices may vary in other regions due to local currency exchange rates, app store pricing, and applicable taxes. For the most accurate pricing in your location, please check the app store listing directly.

To put the cost in perspective: Sentry Pro’s subscription cost is minimal compared to the electricity consumed by running Sentry Mode. A typical 8-hour Sentry Mode session uses roughly 1–2 kWh (about 130–250 W, based on independent tests and owner reports). Run it every night and that adds up to about 7–14 kWh a week, which at typical electricity rates ($0.15–0.30/kWh) costs roughly $1–4 — about the same as or more than a week of Sentry Pro (under $1 a week on the annual plan).

There is absolutely no excuse not to use Sentry Pro if you’re already utilizing Sentry Mode and appreciate the peace of mind it offers.
