Kahunas is a cloud platform for personal trainers, fitness professionals and coaching businesses. Clients view plans, log workouts, track progress, record nutrition and complete check-ins. Coaches manage those records, publish content, message clients, schedule events and take payments.
Apps are available on iOS and Android, with a web platform and wearable syncing.
What it does
Kahunas gives coaches one place for client records, workout and nutrition plans, check-ins, habits, progress, communication, content, scheduling, payments and automations. Clients can open assigned workouts, log sessions, track progress, record food and complete custom forms; coaches review the results.
It runs through iOS, Android and the web as a cloud service. The facts do not describe a separate Kahunas watch app or say that a phone is required. Wearable data can sync into check-in forms.
On the wrist
Kahunas does not name Apple Watch, Wear OS, Garmin, Fitbit or another watch platform. It says clients can connect wearable devices so their data flows into check-in forms.
The named client apps are Kahunas-branded iOS and Android apps, while branded iOS and Android apps are included on Ultimate. No watch display or watch-only function is specified.
Getting started
There is no free plan, but the pricing page offers a 14-day trial for its plans. The help center is organized around accounts, workouts, nutrition, clients, forms, apps, plans, billing, integrations and automations.
Essentials includes one-to-one live onboarding. Kahunas also provides chat for contact and support.
Strengths
The platform covers both coaching work and client administration. Its exercise library has more than 1,000 exercises, and coaches can upload exercises or import them from YouTube.
Nutrition logging includes a database advertised at 1.6 million verified foods and 800,000 barcodes, with restaurant items, servings, macronutrients and micronutrients. Coaches can also drip audio, video, documents and PDFs from a content library.
Custom weekly check-ins, daily accountability forms, wearable syncing and client messaging keep progress information in the same workspace. Stripe and PayPal payments are supported without commission on sales, according to Kahunas.
Catches
There is no free plan. Client limits vary by plan: Essentials allows 25 clients, Growth 50, and Ultimate is unlimited.
Branded iOS and Android apps with the coach’s own app-store listings are reserved for Ultimate. Zapier is included with Ultimate and available as an extension on Growth; Kahunas-branded apps can be used on any plan.
The facts name no specific watch platforms, and they do not describe a public API or SDK documentation section. Kahunas is described as a cloud platform, with no self-hosting option or open-source license stated.

The short of it
Kahunas fits coaches who want client management, training, nutrition, forms, messaging, content and payments in one cloud service. The 14-day trial lets a coach examine the workflow before paying, but there is no ongoing free tier. Check the client cap and whether a Kahunas-branded or fully branded mobile app matters: the latter starts with Ultimate. Wearable syncing is mentioned, yet no watch maker or watch interface is named, so buyers seeking a defined wrist experience should verify that point first.
