Kahunas
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.
- Workout, nutrition, forms, habits and messaging share one workspace
- Nutrition database lists 1.6 million foods and 800,000 barcodes
- Wearable data can sync into check-in forms
wger Workout Manager
Choose wger if you want one free system for routines, nutrition, body measurements, progress photos, and basic gym administration, with the option to run it yourself. Its open code, API, and community translations suit technically minded users and organizations that need control over deployment. Look elsewhere if named watch support or a clearly documented first-run flow is essential. The routine design is also a poor match for workouts that change from session to session.
- Free plans include workout, nutrition, and weight tracking.
- Custom routines support automatic weight progression.
- Self-hosting and a REST API are available.

Free access
wger provides a free plan and also identifies itself as free and open source under AGPL-3.0-or-later. Its free plan includes workout tracking, nutrition and weight tracking, open-source code and self-hosting. Kahunas has no free plan. It offers a 14-day trial for its paid plans, after which the listed Essentials, Growth or Ultimate price applies.

Coaching and fitness tools
Kahunas covers a wider coaching workflow: client records, workout and nutrition plans, check-ins, habits, progress, messaging, content, scheduling, payments and automations. Coaches can review workout logs, create custom forms, upload media and documents, and manage leads. wger focuses on custom routines, automatic weight progression, calorie logging, body measurements, progress photos, an exercise wiki and basic gym administration. Both track fitness activity, but Kahunas offers more business and coach-management functions. Kahunas wins on breadth for coaching businesses.

Integrations and extensions
Kahunas lists Stripe, PayPal, wearable syncing and Zapier integration. Zapier is included in Ultimate and available as an extension on Growth. It also lists an API, while its help-center navigation exposes mobile-app developer guides but no public API or SDK documentation section. wger provides a REST API at /api/v2/ with filtering, ordering, pagination and public and authenticated resources. Every endpoint has OpenAPI documentation, and an official typed Python client supports synchronous and asynchronous use. wger wins on documented integration depth.

Platforms and deployment
Kahunas runs on Android, iOS and the web, and lists an API. Its branded iOS and Android apps are included in Ultimate; Kahunas-branded apps can be used with any plan. The reviewed pages describe it as cloud-based and provide no self-hosting option. wger supports Android, iOS, Linux, web, API and self-hosted deployment. A Docker Compose instance is documented. wger wins because it offers more listed platforms and a documented self-hosting path.

Support and documentation
Kahunas provides a help center covering accounts, workouts, nutrition, clients, forms, apps, plans, billing, integrations and automations. Its pricing page includes 1 to 1 Live Onboarding for Essentials and directs visitors to chat for support. wger provides documentation for operation, installation, administration, development, API use, contribution and changelogs, and invites contact through Mastodon, Discord or its issue tracker. The facts show different support channels and documentation scopes, but do not establish that one is better. This round is a tie.
API and developer access
Kahunas is listed with an API among its features, but the official help-center navigation does not show a public API or SDK documentation section. wger documents its REST API under /api/v2/, with JSON responses, filtering, ordering, pagination and public or authenticated resources. It supplies generated OpenAPI documentation with JSON schema, Swagger UI and ReDoc, plus an official typed Python client with synchronous and asynchronous calls. Release 2.7 also lets wger act as an OAuth2 provider. wger wins clearly on developer detail.

Security and data controls
Kahunas' privacy policy says it uses encryption in transit and at rest, role-based access controls, regular security audits and vulnerability scans, secure backups and incident-response protocols. It says health data from services such as Apple Health and Google Fit is accessed only with permission, which users can revoke in account settings. wger's security policy says older versions are unsupported, and release 2.7 changed password hashing to Argon2 with migration on login. Kahunas wins because its listed controls cover more security and health-data handling areas.

The short of it
Choose Kahunas when the work is running a coaching service: it brings client records, plans, check-ins, habits, messaging, content, scheduling, payments, automations and optional branded apps into one paid platform. Choose wger when cost, open-source licensing, self-hosting or developer access matters more. wger also suits personal workout, weight and diet tracking and basic gym administration. Kahunas has the broader business workflow; wger has the broader deployment and API model. Neither is a universal choice: the better fit depends on whether you manage clients or manage your own fitness system.
