Trainera vs Kahunas: Honest 2026 Comparison

TL;DR

Kahunas (kahunas.io) is an online-only coaching platform whose main selling point is a branded white-label app at 99 USD per month for unlimited clients (as of June 2026). The catch is that the client-facing mobile app rates around 3 stars, the nutrition module is weak, there is no calendar for in-person or hybrid coaching, and there is nothing for gyms or studios. So even its headline app benefits little if clients dislike using it.

Trainera is a web and mobile platform for personal trainers, online coaches and gyms, with local-language and local-currency pricing, cash and bank-transfer tracking (no fee just to enable payments), a full white-label native app under your own brand, a full gym and studio module, omnichannel messaging with voice messages and live video calls, a native Apple Watch app, AI nutrition and food scanning included, video form-review, Calendly-style booking with two-way calendar sync, achievements and streaks, and a public profile, program storefront plus marketplace for client acquisition. Trainera starts free, then Starter is 19.99 USD per month for 10 clients, Pro 49.99 USD for 30, and Business 99 USD for 100. If you coach online-only and want unlimited clients at a flat 99 USD, look hard at Kahunas. For almost everyone else, Trainera is the stronger all-round choice and now matches Kahunas on a branded white-label app while including far more. You can start free.

Kahunas Pricing (2026): headline number vs the real bill

Kahunas pricing is clean enough: Essentials at 35 USD for 25 clients, Growth at 69 USD for 50, and Ultimate at 99 USD for unlimited clients with the branded app included, about 25 percent cheaper on annual billing. The catch is what is bundled. Pricing is USD-only, with no local-currency option and no way to record cash or bank-transfer income inside the tool.

Trainera starts free, then Starter is 19.99 USD per month for 10 clients, Pro 49.99 USD for 30, and Business 99 USD for 100, with local-currency pricing for Balkan markets (BAM, EUR, RSD, HRK). The bigger difference is what is included at every tier: AI, the full nutrition module, and client payments are part of the plan, not add-ons. There is no fee just to switch payments on, and cash and bank transfer are tracked alongside Stripe and PayPal.

Where Kahunas competes and how Trainera answers

Kahunas posts solid coach-side review numbers: roughly 4.8 on Trustpilot from over 400 reviews and around 4.9 on Capterra from 60. Those reviews praise plan building, chat and tracking, and Trainera covers all of that, then adds the nutrition, gym management, local payments and client acquisition Kahunas leaves out.

Branded app and unlimited clients

The Ultimate plan at 99 USD includes unlimited clients and your own branded iOS and Android app with your own store listing, no setup fee. A self-branded app is no longer a reason to leave Trainera, though: Trainera also includes a full white-label native app under your own brand, plus a branded public web page, a custom domain on higher tiers, a marketplace listing, a program storefront and a per-trainer SEO blog engine, all in the plan, and it offers API access on request. Where Kahunas still has a narrow edge is its flat unlimited-client price at 99 USD, so a very large remote roster on one plan is the one pricing case worth weighing.

Check-in and accountability workflow

Kahunas offers check-ins with custom forms, habit tracking and progress-photo overlay. Trainera matches the check-in workflow with weekly check-in forms, side-by-side progress photo comparison and body measurements, and goes further with gamification: XP and levels, more than 40 achievements across 9 categories, streaks for workouts, progressive overload, protein, calorie logging and water intake, plus weight milestones like the 100 kg Club. Accountability stops being a form to fill in and becomes something clients chase.

Lead-gen and automation

Kahunas includes lead-generation funnels, email automations and a churn-prediction Health Score AI, and it takes no commission on client payments. Trainera answers acquisition differently: a public branded page and a listing in the Trainera marketplace where prospective clients actually browse for a coach, plus a per-trainer SEO blog engine so your content ranks under your own profile.

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. 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. Trainera ships a native Apple Watch app (login, workout list, active workout, rest timer, heart rate), iOS Live Activities on the lock screen and Dynamic Island, and an Android foreground service so background workout tracking is not killed mid-set.

Nutrition is the weakest module

Reviewers describe the Kahunas 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. Trainera treats nutrition as a first-class module: a meal library with per-meal macro targets, a global USDA-synced food database, recipes, calorie and water tracking, AI food-photo analysis, barcode scanning via OpenFoodFacts, AI-generated shopping lists by day and combined, and dietary and allergen handling that never violates a vegan, vegetarian or paleo plan.

No gym or studio support

Kahunas is built for solo online coaching. If you run a gym or studio, there is nothing for memberships, check-in, group classes or staff. Trainera includes a full gym module where the gym is its own entity managing multiple trainers and members, with membership tiers and packages, a 5-digit member number for check-in, group training slots and reservations with capacity and level filters, staff roles with email invitations, equipment inventory, working hours and per-gym white-label branding with a custom domain.

No real calendar or booking

There is no calendar or session booking in Kahunas, so it is weak for in-person and hybrid trainers. Trainera includes Calendly-style 1:1 appointment booking with availability windows and two-way Google and Outlook calendar sync, covering in-person, online and hybrid coaching.

Health connections are limited

The Kahunas Apple Health connection does not auto-pull cardio and steps reliably, and there is no Apple Watch app. Trainera syncs the six trackers most clients actually wear: Apple Health, Google Health Connect, Fitbit, Polar, Google Fit and Huawei Health, pulling steps, heart rate, calories, sleep, workouts, weight, body fat and hydration. Garmin is on the Trainera roadmap and not live yet, so a heavily Garmin roster is the one wearable gap to factor in.

Single-channel messaging

Kahunas chat lives inside its app. Trainera adds omnichannel messaging: connect WhatsApp Business, Facebook Messenger and Viber so external client messages land in the same inbox you use for in-app chat, which matters in markets where clients live on WhatsApp and Viber.

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. Trainera can be cancelled any time from the app, with no UAE-law contract.

What Trainera does differently

Trainera is one platform for solo trainers, online coaches and gyms, on web plus iOS and Android. It covers client management, a workout builder with a video exercise library (supersets, circuits, progression, levels and equipment flags), nutrition with a meal library and macro tracking, AI food-photo and barcode scanning, real-time chat, and progress tracking with measurements, photos, streaks and achievements. AI is included in paid plans (training and nutrition plan generation, single workouts, food chat, AI shopping lists and weekly insights), not a paid add-on. Client payments run through Stripe, PayPal, bank transfer and cash tracking, with no fee just to enable payments, plus subscriptions, one-time invoices, installment plans and trial management. On top of that, every trainer gets a full white-label native app under their own brand and a program storefront to sell programs directly, and the interface is available in 21 languages including Bosnian, Croatian, Serbian and English.

Who should pick which

Kahunas fits a narrow profile: an online-only physique or bodybuilding coach with a very large remote roster, whose coaching is purely check-in driven, and who does little nutrition work. If that is you exactly, the 99 USD flat unlimited-client price is competitive, since Trainera caps Business at 100 clients.

Trainera is the better fit if you coach in the Balkans or EU, clients pay in cash or by transfer, you want a local-language interface and local-currency pricing, you run in-person or hybrid sessions, you run a gym or studio, or you want a serious nutrition module with AI food scanning, omnichannel messaging, a native Apple Watch app, achievements, and acquisition built in through a public profile, marketplace and SEO blog. It also lets you start free before paying anything.

The bottom line

Kahunas is an established online coaching tool, and a branded-app price is the one box it ticks. But weigh the whole picture, the client app your clients live in every day, nutrition, payments, gym management, messaging and language, and Trainera comes out ahead for essentially every coach and every gym. The honest concessions are narrow: Kahunas wins on a flat unlimited-client price for very large rosters, and a Garmin-heavy roster is the one wearable gap until Garmin ships on Trainera's roadmap. On everything else, price, all-inclusiveness, the gym module, cash and transfer payments, local language and currency, AI nutrition, achievements and marketplace discovery, Trainera is the smarter overall choice. The honest way to decide is to try it. Create a free Trainera account and move your first clients over with no risk.
