Choosing the platform you run your coaching business on is a decision you live with every day, so it deserves an honest comparison. This is a fair, side-by-side look at Trainera and Hubfit (formerly hubfit.io, now hubfit.com). All pricing is accurate as of June 2026.

TL;DR

Hubfit is a polished, genuinely all-in-one platform for English-speaking solo online coaches. The UI is praised, support is fast, and every feature is included on every plan with no paid add-ons. It is a strong, cheaper alternative to Trainerize.

Trainera is built for trainers who want local-language support, local-currency pricing, flexible client payment methods (including cash and bank transfer), and a marketplace that brings in new clients. It is the stronger fit for the Balkan market and for trainers who want to be discovered, not just to manage existing clients.

Pricing

Hubfit charges in US dollars only. As of June 2026, Standard is $39 per month for up to 50 clients, Premium is $69 for up to 100 clients, and Ultimate is $119 (which adds team members). There are larger Ultimate tiers up to $419 for 500 clients. Paying annually gives two months free, no contract, with a 14-day trial. Every feature is included on every plan, which is genuinely Hubfit's strongest pricing argument against Trainerize-style paid add-ons.

Trainera uses local-currency pricing. In Bosnia, Starter is from 19.99 KM per month (10 clients), Pro is 44.99 KM (30 clients), and Business is 84.99 KM (100 clients). Croatia and Montenegro pay in euros, Serbia in dinars, and the US in dollars (Starter $19.99, Pro $49.99, Business $99). There is also a free plan, and everything is included.

The headline difference: Hubfit's $39 entry point is roughly four times Trainera's Starter for the Balkan market, and you pay in a currency you may not earn in.

It is worth being precise about what you get for the money on each side. Hubfit's tiers are differentiated mainly by client count rather than features, so even the cheapest plan is fully loaded. That is a genuine strength and the main reason coaches pick it over platforms that lock features behind add-ons. Trainera follows the same all-included philosophy on paid plans, but starts lower and lets you begin on a free plan before you commit a cent. If you are early in your coaching career, the ability to start free and only pay once you have paying clients changes the math considerably.

One pricing detail to note on the Hubfit side: it offers a custom branded standalone app, but that price is not published and requires contacting the team. There is nothing wrong with that, but it means you cannot fully budget for a branded app up front without a sales conversation.

Features and product experience

Both platforms cover the core coaching workflow well. Hubfit's workout builder handles supersets, circuits, intervals and AMRAP. Its nutrition module includes a barcode scanner and in-app food logging. It also has a check-in inbox, habit tracking, a community feed with challenges and leaderboards, voice notes in chat, and a broad set of wearable integrations: Apple Health, Health Connect, Fitbit, Garmin, Whoop, Oura, Cronometer and Zapier. Reviewers consistently praise the smooth UI and the speed of support and feature updates.

Trainera covers client management, a workout builder with a video library, nutrition plans with a meal library, macros and AI food-photo analysis, real-time chat, and progress tracking with measurements, photos, streaks and achievements. AI is included in paid plans for training, nutrition and workout generation plus weekly insights, with no add-ons. Health integrations include Apple Health, Google Fit, Fitbit, Polar and Huawei Health. Trainera ships as a web app plus separate iOS and Android apps, whereas Hubfit uses one app where coaches toggle between trainer and client roles, which some reviewers find a little awkward.

One detailed Trustpilot review of Hubfit from 2024 noted a small out-of-the-box recipe library, some basic exercises missing from the library, and a sparse client dashboard. A few app-store reviews mention minor issues like not being able to pause a workout when switching screens, limited food portion options and occasional freezing. These are minor and the team iterates quickly, but they are worth knowing.

Languages and localization

Hubfit's app supports ten languages: English, Norwegian, Dutch, Spanish, Turkish, French, Portuguese, Bulgarian, Czech and Romanian. None of them are Bosnian, Croatian, Serbian or Montenegrin. If your clients are not comfortable in English, that gap directly hurts engagement, because clients use an app most when it speaks their language.

Trainera offers its interface in 21 languages, including Bosnian, Croatian and Serbian, with support in the local language. For trainers serving Balkan clients, this is the single most decisive difference.

Payments

Hubfit processes client payments through Stripe. That is clean and modern if all your clients pay by card. Trainera supports Stripe, PayPal, bank transfer and cash tracking, which reflects how many clients actually pay in markets where card-only is not the norm. Being able to log a cash or bank-transfer payment inside the same platform keeps each client's financial picture in one place.

This matters more than it first appears. If a chunk of your clients pay in cash or by bank transfer and your platform only understands card payments, you end up keeping a parallel spreadsheet to track who actually paid. That defeats the point of an all-in-one tool. Trainera lets you record those payments natively, so your revenue picture and your client management live together rather than in two disconnected systems.

Group training, gyms and hybrid coaching

Beyond one-to-one online coaching, Trainera also supports group training, gym management and hybrid setups where you coach the same client both in person and online. This is common in markets where a trainer works out of a gym during the day and runs online programs alongside it. Hubfit is squarely focused on the online solo-coach use case, which it does well, but it is not built around in-person gym operations in the same way.

Getting new clients

This is the biggest strategic difference. Hubfit manages the clients you already have but does not bring you new ones; there is no marketplace. Trainera gives every trainer a public web page with their own branding (and a custom domain on higher tiers) plus a listing in the trainera.fit marketplace, so prospective clients can find you, see your specialty and send a request. If you want to understand how clients evaluate coaches, our guide on how to find the perfect personal trainer shows the buyer's side of that journey.

Who each is best for

Choose Hubfit if

You are an English-speaking solo online coach
You have roughly 20 to 100 clients who all pay by card
You want a cheaper, modern all-in-one alternative to Trainerize with strong client UX and no paid add-ons

Choose Trainera if

Your clients speak Bosnian, Croatian, Serbian or Montenegrin
You want local-currency pricing, a free plan and a low entry point
You need to track cash or bank-transfer payments, not just card
You want to be discovered by new clients through a marketplace, not only manage existing ones
You want AI training and nutrition tools included in your plan

The honest verdict

Hubfit is a genuinely good product with a modern interface, fast support and a transparent all-included pricing model, and it is a smart pick for English-speaking solo coaches. It is also young: founded around 2022 by a small London-based team, with a still-small review footprint, and a Trustpilot profile that is frozen on the old hubfit.io domain where new reviews can no longer be left. None of that is a flaw in the software, but it is context worth weighing.

For trainers in the Balkans, the calculus is simpler. Local languages, local currencies, flexible payments, a free plan and a marketplace that brings in new clients line up directly with how coaching businesses grow in this region. Create a free Trainera account and see the difference for yourself.
