Copper Keto Companion is now on the App Store
June 9, 2026 · 3 min read
Copper Keto Companion is live on the App Store. It's the keto coach you talk to: say what you ate and it works out the net carbs and macros, then keeps a running total against your day. No forms, no scrolling a food database.

What it does
Copper Keto Companion turns logging into one spoken sentence: you say what you ate, and it returns the net carbs, the macros, and where that leaves you for the day. That's the whole interaction.
The coaching is the point. It reads back the number and the context, not a pep talk — if a meal puts you over your ceiling, it says so plainly. Log a few days and it starts to recognize your patterns and tracks your weight trend from Apple Health.
What it costs
Copper Keto Companion is $14.99 a month, with no annual option anymore. Every new account gets a free week first — seven days of full access with no card required, starting the moment you send your first message. It's on iPhone, US only for now.
You can run a full day of real meals through it before you decide whether it earns a place on your phone.
The research behind it
Copper Keto Companion is built on published research, and that research is public. We keep a curated, source-linked index of the studies behind keto — weight, blood sugar, appetite, and the carb science — including the trials that found no advantage.
Read it at the research index: every entry links to the primary source, with what it actually found and where the evidence is mixed.
What it is, and what it isn't
Copper Keto Companion tracks and coaches — it doesn't promise a number or treat any condition. It gives you honest math and context, not medical outcomes.
This is general nutrition information, not medical advice. If you take medication, are pregnant, or manage a condition like diabetes or high blood pressure, talk to your doctor before starting keto. The app handles the numbers; your clinician handles the medicine.
Try it
Copper Keto Companion is on the App Store now, and every account gets a free week to start. See how it handles a real day of meals — get the app, or read more on the app page.
Common questions
Is there a free trial? Every new account gets a free week — seven days of full access with no card required, beginning with your first message. After that, Copper Keto Companion is $14.99/mo; there's no annual plan anymore. Apple may also offer its own short trial when you subscribe, for eligible accounts, shown in the App Store purchase screen.
What iPhone does it require? iPhone running iOS 26 or later. US only.
Does it work without a subscription? The app requires an active subscription once the free week ends. The free week is free and gives you full access, no card required.
