TL;DR

Kahunas (kahunas.io) is a well-liked online coaching platform with the cheapest branded white-label app on the market at 99 USD per month for unlimited clients (as of June 2026). Coaches rate it highly. The catch is that the client-facing mobile app rates around 3 stars, the nutrition module is weak, and there is no calendar for in-person or hybrid coaching.

Trainera is a personal training platform built for the Balkans and beyond, with local-language and local-currency pricing, cash and bank-transfer payment tracking, a calendar for hybrid coaching, AI included in paid plans, and a public profile plus marketplace for client acquisition. If you coach online-only and want the cheapest branded app, look hard at Kahunas. If you coach hybrid, take cash, or want a stronger nutrition module and built-in client acquisition, Trainera fits better. You can start free.

What Kahunas does well

Let us be fair before the comparison. Kahunas earns its reputation among coaches: roughly 4.8 on Trustpilot from over 400 reviews and around 4.9 on Capterra from 60. That is genuinely strong, and a few things explain it.

The cheapest branded app deal

The Ultimate plan at 99 USD per month includes unlimited clients and your own branded iOS and Android app with your own app-store listing, no setup fee. If a branded app is your top priority, this is honestly hard to beat on price.

Check-in and accountability workflow

Kahunas has a polished check-in system: custom check-in forms, habit tracking, and progress photo overlay. For a coach running weekly check-in-driven coaching, this is excellent.

Lead-gen and automation

It includes lead-generation funnels, email automations, and a churn-prediction "Health Score AI." It also takes no commission on your clients' payments.

Where Kahunas falls short

Now the honest part. These are the points that send coaches looking for an alternative.

The client app is the weak link

The headline finding is the split between coach ratings and client ratings. While coaches rate Kahunas 4.8 to 4.9, the client-facing mobile app rates around 3.2 of 5 on the Apple App Store (UK storefront, 137 ratings) and around 3.0 of 5 on Google Play (about 210 ratings), as of June 2026. Your clients live in that app every day. App Store reviewers report frequent crashes and lost workout data mid-session, with one describing it as "sheer luck if the workout saves." A great coaching program still feels broken if the app loses the session.

Nutrition is the weakest module

Reviewers describe the food data as "constantly wrong." The database is smaller than MyFitnessPal, there is no MyFitnessPal or Cronometer integration, macro tracking is basic, and you cannot build and save meals. For nutrition-focused coaching, that is a real gap.

Simpler workout builder

It has fewer advanced parameters than some competitors - tempo, RIR/RPE, and supersets are limited.

No real calendar or booking

Kahunas is an online-coaching tool. There is no real calendar or session booking, so it is weak for in-person and hybrid trainers.

Health connections are limited

The Apple Health connection does not auto-pull cardio and steps reliably, and there is no Apple Watch app.

Cancellation fine print and jurisdiction

Per the official Terms, you must cancel at least 48 hours before renewal or you owe the full next term with no refund, and you can only cancel via the website, not the app. The contract is governed by UAE law and Dubai courts (the company is Kahunas FZE, Sharjah, UAE). The 14-day trial auto-converts to paid unless cancelled, and US and EU users report support timezone friction. Pricing is USD-only, with no Balkan language support and no cash or bank-transfer payment tracking.

What Trainera does

Trainera is a platform for personal trainers with a web app plus iOS and Android apps. It covers client management, a workout builder with a video exercise library, nutrition plans with a meal library and macro tracking, AI food photo analysis, real-time chat, and progress tracking (measurements, photos, streaks, achievements).

AI is included in paid plans (training and nutrition plan generation, workouts, weekly insights), not a paid add-on. Client payments run through Stripe, PayPal, bank transfer, and cash tracking - which matches how most clients in the region actually pay. Every trainer gets a public web page with their own branding (custom domain on higher tiers) plus a listing on the Trainera marketplace, so acquisition is built in, not just management. If getting clients is your bottleneck, see our guide on finding clients as a personal trainer.

Trainera supports group training, a gym management module, and in-person, online, and hybrid coaching with a calendar and scheduling included. Health integrations cover Apple Health, Google Fit, Fitbit, Polar, and Huawei Health. The interface is available in Bosnian, Croatian, Serbian, and English, with support in the local language, and there are no UAE-law contracts - you can cancel any time from the app.

Who Kahunas is best for

Kahunas is a strong choice if you are an online-only physique or bodybuilding coach with 25 to 100-plus remote clients, you want the cheapest branded app, and your coaching is driven by structured weekly check-ins. If you can live with a basic nutrition module and the occasional client-app bug, the 99 USD unlimited branded-app deal is genuinely competitive.

Who Trainera is best for

Trainera is the better fit if you coach in the Balkans or EU and clients pay in cash or by transfer, you want a local-language interface and local-currency pricing, you run in-person or hybrid sessions and need a calendar, you want a serious nutrition module with AI food photo analysis, and you want client acquisition built in through a public profile and marketplace. It also lets you start free before paying anything, and there are no UAE-law contracts to navigate.

The white-label app question

Since the branded app is Kahunas' headline feature, it is worth being precise about it. A white-label app means your clients download an app with your name and your icon from the app store, rather than the platform's app. For branding, that looks professional, and many coaches genuinely want it.

There are two sides, though. First, a branded app is only as good as the code underneath it. If the client app occasionally loses workout data, that failure now carries your name, not the platform's. Second, having your own listing means a client has to find and download yet another app, which is one more step where some people drop off before they even start.

Trainera takes a different route: instead of a separate app per trainer, you get a public web page with your own branding (custom domain on higher tiers) plus a marketplace listing, while clients use one stable shared Trainera app. You get branding through your page and profile, and clients get an app that is maintained centrally. It is a different trade-off, not necessarily a worse one - it depends on whether your own icon on a phone matters more to you than the stability of the day-to-day experience.

Migrating from Kahunas without losing momentum

If you already use Kahunas and are weighing a switch, a few practical notes. First, check your renewal date and the 48-hour cancellation rule before you cancel, so you do not get billed for another full term. Cancellation goes through the website, not the app.

Second, export everything you can before closing the account: training plans, nutrition plans, progress photos, and client measurements. The smoothest path is a gradual move - while your Kahunas account is still active, open a Trainera account, move the first few clients over, and run one full week to see how check-ins, chat, and tracking feel. Only once you are confident do you move the rest and cancel the old subscription on time.

Third, tell clients in advance why you are switching tools and what they gain, for example a more stable app, a better nutrition module, or the ability to pay by cash or transfer with clean record-keeping. Clients accept change far more easily when they understand the benefit for themselves rather than feeling it is just admin churn on your side.

The bottom line

Kahunas is a legitimately good online coaching tool with the best branded-app price on the market. But weigh the whole picture - the client app your clients live in, nutrition, payments and language - and Trainera comes out ahead for most coaches. But if your reality is hybrid coaching, cash payments, local language, and a need to actually attract clients rather than just manage them, Trainera is built for that exact situation. The honest way to decide is to try it yourself. Create a free Trainera account and move your first clients over with no risk.
