Hevy
Hevy suits lifters seeking an organized log, routine planning, progress records, and community accountability on phones, browsers, and supported watches. Its free tier works for a small routine collection, though regular trainers can reach the limits. Pro becomes relevant for unlimited routines, extended graph history, measurement tracking, or Hevy Trainer. Review the default public-profile choice if you prefer less sharing, and remember that API use is reserved for Pro accounts.
- Records sets, rest, notes, routines, and user-created exercises
- Apple Watch and Wear OS support includes offline workout recording
- Provides records, estimated one-rep max, volume, and exercise history
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
Round by round
Published pricing
Hevy publishes a free plan, plus Pro at $2.99 a month, $23.99 a year or $74.99 one time. Pro adds unlimited routines, custom exercises and graph history, with Hevy Trainer and, on listed plans, unlimited measurement tracking. Kahunas starts at $35 a month for Essentials, with Growth at $69 and Ultimate at $99. Annual prices are $315, $621 and $900. Kahunas pricing is for a coaching platform with client limits or unlimited clients by plan. Hevy wins on the lower published entry price and the availability of a free plan.
Hevy takes this round
Free plan and trial
Hevy has a free plan and a free trial. The free plan allows four routines, seven custom exercises and three months of graph history, with limited measurements. Kahunas has no free plan, but its pricing page offers a 14-day free trial for its paid plans. Hevy therefore gives users an ongoing no-cost option, while Kahunas requires payment after the trial. The limits matter: users who need more routines, exercises, history or measurements must move to Hevy Pro. Hevy wins because only it provides a continuing free tier.

Workout and coaching features
Hevy focuses on weight-training sessions: logging, routines, warmup, drop and failure sets, rest timers, notes, custom exercises, charts, personal records, estimated one-rep max, exercise history and community activity. Pro adds personalized programs, progressive-overload recommendations, suggested weights and repetitions, and reports. Kahunas covers workout and nutrition plans, client records, check-ins, habits, content, messaging, scheduling, payments and automations. Its exercise library has more than 1,000 exercises, and its nutrition database lists 1.6 million verified foods and 800,000 barcodes. Kahunas wins for the broader coaching workflow.

Integrations and connected services
Hevy offers Strava sharing, Apple Watch and Wear OS syncing, data export to spreadsheet-compatible files, and a public REST API for workouts, routines, exercise history, measurements and user information. The API is restricted to Hevy Pro users, and its documentation warns that the structure may change or be abandoned. Kahunas lists Stripe, PayPal, wearable syncing and Zapier; Zapier is included in Ultimate and available as a Growth extension. It also supports payments without commission on sales. Kahunas wins for the wider set of listed business integrations.

Platforms
Both products list Android, iOS, web and API availability. Hevy also provides a browser app for creating routines, reviewing exercise progress and viewing friends’ workouts, while its wearable support covers Apple Watch and Wear OS, including offline workouts and routine synchronization. Kahunas provides a cloud platform, mobile apps and branded iOS and Android apps on Ultimate, with app-store listings included there.
Support and documentation
Hevy directs customer-service questions to [email protected] and maintains a searchable help centre covering setup, features, troubleshooting, integrations, imports, exports and subscriptions. Kahunas provides a help centre covering accounts, workouts, nutrition, clients, forms, apps, plans, billing, integrations and automations. Its pricing page says Essentials includes one-to-one live onboarding and directs visitors to chat for support. The facts describe different support channels rather than a clear difference in overall coverage or quality. Neither product can be awarded this round, so it is a tie.
Privacy and security
Hevy’s stated security details include encryption in transit, no data sharing with third parties in its Google Play listing, deletion requests, private profiles and controls for limiting social features. Its cookie policy describes access, correction, deletion, consent withdrawal, portability and objection rights for covered users. Kahunas describes encryption in transit and at rest, role-based access, audits, vulnerability scans, backups and incident response. Health data from Apple Health and Google Fit is accessed with permission that users can revoke. Both publish concrete privacy or security controls, so the facts do not separate them.
API and developer access
Hevy publishes an OpenAPI 3.0 REST API covering workouts, routines, exercise templates, folders, exercise history, body measurements and user information. Access is currently restricted to Hevy Pro users, and the documentation says the structure may change or be abandoned. Hevy lists no official SDK, open-source licence or self-hosting package. Kahunas is listed as having an API by Software Advice, but its official help-centre navigation shows mobile-app developer guides rather than public API or SDK documentation. Hevy wins because its public API scope is documented directly.
