FAQ

Questions before you download.

Is Specular free?

Yes. Specular is a free download, and you can create workouts and log sessions without paying, with some limits.

Specular Pro is an optional monthly or yearly subscription. It adds full workout history, Training Load, workout suggestions and detailed metrics. The monthly plan may include a free trial for new subscribers. Prices and the trial's length are shown in the app before you subscribe.

Do I need to create an account?

No. Specular has no sign-up and no login.

Subscriptions are handled by Apple through your Apple ID.

Where is my workout data stored?

On your iPhone. If iCloud is on for Specular, workouts, sessions and preferences also sync through your private iCloud account, which we can't access. There's no Specular account and no copy on our servers.

Specular does not use third-party analytics or advertising SDKs. If you use a workout program, the app sends anonymous program usage, which you can turn off in Profile. The Privacy Policy lists the cases where data leaves the device, such as when you create a workout share link.

Does Specular work with Apple Health?

Yes. With your permission, Specular reads workouts, heart rate, energy, sleep, HRV and body measurements from Apple Health, and writes the sessions you log back to it.

You can change what Specular can access at any time in the Health app.

Is there an Apple Watch app?

Not at the moment. Specular runs on iPhone.

Workouts recorded on Apple Watch and saved to Apple Health can still appear in Specular.

Can I import or export my workouts?

Yes. You can export workouts as CSV, JSON, TXT or .specular files and import workout files back in.

Both are in Profile, under Data & Privacy, then Manage Data.

Can I share a workout with someone?

Yes. Specular creates a link to a workout routine that anyone with the link can open.

If the person has Specular, the link opens the workout in the app. If not, it takes them to the App Store.

Is Specular medical advice?

No. Training load, recovery and suggestions are informational estimates based on your data.

They are not a substitute for professional medical or fitness guidance. See the Terms of Service.
