Kahunas vs Relay Athletic: price, athlete app, AI and what each one covers.

Kahunas vs Relay Athletic price at 10, 25, 50 and 100 clients

Kahunas prices per seat: one seat for each active client and each team member, USD 5.00 a month from 3 seats, 2.50 from 25, 2.00 from 50 and 1.50 from 100, with 20 percent off for yearly billing (kahunas.io/pricing, checked 12 November 2026). Kahunas says you, the owner, never take a seat, so we count clients only. Add a seat for each team member.

Relay prices by tier of members. Its pricing page says one member is one seat and that a seat is either a coach or an athlete on your roster. Its price calculator starts at one coach, so we count you as one seat on top of your clients (relayathletic.com/pricing, checked 12 November 2026). Relay Plus tiers on the page: 5 members USD 14.99, 15 members 34.99, 25 members 49.99, 35 members 64.99, 50 members 89.99, 75 members 119.99, 100 members 149.99, 250 members 199.99. Prices below are monthly.

Three notes. Relay says it bills in euros, or US dollars if you are in the United States, so the euro figure for your account may differ from the dollar list we read. Relay says paying yearly gives you two months free; Kahunas takes 20 percent off. And the tiers are not the same shape: a Relay tier is a ceiling you pay for, so 25 clients plus you is 26 members, which Relay bills as the 35-member tier, while Kahunas bills per seat for the number of seats you choose, and bills a bigger plan when that costs the same or less (kahunas.io/pricing). Relay also lists Enterprise for clubs and academies at "Contact us", and publishes no price for it.

Client app and branding

Kahunas gives clients a web app that installs from your link, on every plan. From 200 clients your logo and brand colour go on it, with no developers and no store listing (Kahunas branded app page, checked 12 November 2026).

Relay says athletes download its app on iPhone or Android, enter your invite code and find your program on the phone, and that an athlete who would rather not install anything can train from a browser. On branding it says you add your logo and set a cover image for each program, so the first thing athletes see is your work (Relay athlete app page, checked 12 November 2026). Relay's pricing page lists a branded athlete experience on its Plus plan.

Training, exercise library and AI

Relay says it is built around the writing of programs. Its site describes phases and progressions on one calendar, a workout builder, templates, bulk import of exercises and videos, and an AI program builder that drafts inside the rules you give it. It says you can speak a session and have it land structured with Voice AI, and that you can connect Relay to Claude or ChatGPT so the assistant works inside your account (program design, connecting Claude or ChatGPT, checked 12 November 2026). Relay says nothing reaches an athlete until you assign it. Its pricing page lists 1,200+ exercises included, and its FAQ says AI features run through the Google Gemini API and that Relay does not train models on your data.

Kahunas lists a workout builder and a 1,700+ exercise library on its homepage, with your own exercises alongside. For AI it describes Crew assistants in its Kahunas 2.0 post (updated 28 October 2026): Moss drafts workout programs, meal plans and check-in forms from your templates and library, and nothing touches a client's live profile until you review and approve it. Its pricing page lists Crewbots from 50 seats and 250 free AI credits a month on every plan (checked 12 November 2026).

Relay also lists force plate integrations (VALD, Hawkin, Kinvent) on Relay Plus and team scheduling on Enterprise (relayathletic.com/pricing, checked 12 November 2026).

Nutrition and check-ins

Kahunas lists meal plans with macro targets, food logging and a barcode scanner on every plan, with over 1.5 million foods, and a recipe library with per-serving macros on plans from 25 clients (Kahunas nutrition page, checked 12 November 2026). Its check-in forms are built once, filled in on the client's phone and reviewed in one inbox next to the last check-in (Kahunas check-ins page, checked 12 November 2026).

On Relay we found no nutrition plan, meal plan or food logging feature on the home, pricing, program design, athlete app, marketplace and exercise library pages or in the docs we read on 12 November 2026. That may only mean it is not what Relay talks about, so ask Relay if you need it. For check-ins, Relay says you build your own questionnaires and collect what matters, from readiness to pain reports, next to logged load, with unlimited questionnaires on Relay Plus (relayathletic.com, checked 12 November 2026).

Payments and free trial

Kahunas says it takes 0% commission on your sales: clients pay through your own Stripe or PayPal account and you only pay the processor's usual fees. Relay says it takes no transaction fee on marketplace sales, that Stripe fees are deducted and the rest is paid to you, and that every Relay Plus tier includes unlimited marketplace selling. Relay's selling model is a storefront page with your plans and prices, one link to share, and payouts to your own Stripe account (Relay marketplace page, checked 12 November 2026).

On trials, Relay says seven days with full access and no credit card to start. Kahunas says 14 days with every feature of the plan you choose, with your card taken at sign-up and nothing charged until the trial ends. Its feature pages add a 3-month money-back guarantee after the trial. Both checked 12 November 2026.

What each vendor says about moving in

Relay says that bringing your exercises, videos and programs is the first thing it helps with. In its FAQ, Relay says you export your exercise library from your current platform as CSV or Excel and Relay maps the columns, with YouTube and Vimeo links still attached, and programs come across as files, where a spreadsheet, a PDF or a photo of a whiteboard is rebuilt by its AI with the weeks and sessions intact (Relay FAQ, checked 12 November 2026). Its pricing page adds a setup call and hands-on help moving your library and programs across. Relay does not name Kahunas on the pages we read, and we have not tested the move, so treat this as Relay's own description.

On the Kahunas side, its help centre documents a per-client copy of data, with a note that chat messages are not in the copy yet, and a copy of your own account data that Kahunas support prepares and emails within one month (Kahunas help: client data requests, checked 12 November 2026). We did not find a documented export of an exercise library as a spreadsheet, so ask Kahunas support what you can get out. For the steps on the Kahunas side, see how to switch from Kahunas.

Whichever platform you pick, move a few clients first, run a real week and keep your old setup running until you are sure. Check how each vendor handles your clients' payment subscriptions before you move.

Where Coachway fits next to both

We make Coachway, so weigh this section with that in mind. It fits an online fitness or nutrition coach who wants the weekly routine in one place: 1,700+ library exercises, meal plans built from a recipe library, clients logging food in the app, and a client check-in that opens as a card beside the chat, with weight and ratings and the change since the last check-in, so you can review and reply without switching screens. Coachway has an AI food log: a client snaps or types a meal, fixes the estimate and taps Add before anything is logged. The client app and coach dashboard come in eight languages, and Danish, Norwegian, Swedish, Finnish and German were reviewed by native-speaking coaches.

Where it does not fit. Kahunas costs less per client than Coachway. Coachway runs payments on your own Stripe and takes 2.4% per transaction on top of Stripe's fees, where Kahunas and Relay both say they take no cut of your sales. Coachway has no white-label app: your logo and colours go on the progress images you share, not inside the client app. Coachway has no free plan. And if what you want most is to write programs by voice or with AI, or to drive your account from Claude or ChatGPT, Relay says it is built around program writing, with Voice AI and a Claude and ChatGPT connection, and we make no such claim for Coachway.
