The 14-day problem

Your guest is fully engaged for 14 days. Then they vanish.

Weekly stay packages create huge moments of motivation — and then nothing. The relationship dies at checkout. FitKoh exists to keep that flame alive.

Pain 1
High acquisition cost, short shelf life
You spend hundreds in marketing to win a guest, deliver a transformative two weeks, and then never hear from them again. Lifetime value caps at one stay.
Pain 2
Coaching doesn't scale
Your trainers track meals on whiteboards and progress in spreadsheets. One coach can realistically support 5 to 8 guests. The other 50 are flying blind.
Pain 3
No data on what's actually working
You don't know which menu items move, which trainers retain best, or how many alumni would buy a follow-up program. Decisions run on gut feel.
How it works

One platform across the entire guest lifecycle.

From the booking confirmation to the week on property to the alumni message six months later — then back around for the next stay.

Customer journey loop: three phases, one app. The curved path below is the moment a past guest becomes a future booking again.

Before the stay

Warm them up before wheels down

Send magic links and WhatsApp messages with personalised invite copy. Guests can save the PWA before travel so check-in is a tap, not a tutorial.

  • 6-digit codes and magic links from your admin tools
  • WhatsApp-friendly share templates in 5 languages
  • Alumni and referrals re-enter the same loop for the next package
During the stay

From QR at reception to checkout

Guest scans, opens FitKoh in the browser, and redeems their invite. An AI chat collects goals, body metrics, and digital waiver. Then daily menu logging, workouts on your weekly schedule, treatments, and a trainer dashboard with edit-on-behalf.

  • No App Store install; offline-first logging
  • AI meal plans grounded in your kitchen's menu
  • One roster for trainers; photo notes and body metrics over time
After the stay

Stay in the relationship

After checkout, guests keep tracking with their personalised plan. You keep a direct channel for follow-up programs, return-stay offers, and online coaching — without rebuilding trust from zero.

  • Same app, no re-onboarding
  • Trainer can review timelines remotely
  • Foundation for cross-sell and the next loop (see below)

Loop closes: return stay · alumni offers · referrals

For gym owners

Run the back office of your gym from one screen.

A guest roster with merge/role/waiver controls, a menu CMS with AI image generation, weekly workout and treatment schedules, invites, and a feedback inbox — all admin tools that already ship in production.

  • Menu CMS with AI imagesAdd or edit dishes, generate photorealistic images, and let AI estimate macros from a photo. Live in hours, not weeks.
  • Weekly schedulesWorkouts and treatments (massage slots, therapists) tied to days and time slots. Guests book and log directly in the app.
  • Guest roster & invitesProvision accounts via 6-digit invite codes or magic links. WhatsApp share message in your guest's language.
  • Digital health forms & waiversReplace paper. Health questionnaires and waiver signatures captured digitally with your guest's profile.
  • POS import (Poster)Map your existing restaurant POS items to menu entries so meal logging stays consistent with what guests actually eat.

For your guests

A personal nutrition coach in their pocket. From day one.

No download. No new account. They scan a QR code, redeem a code in their browser, and start tracking against your kitchen's actual menu within seconds.

  • QR scan to first logReception hands them a card. They open the app, redeem an invite code, and log their first meal — usually before they finish breakfast.
  • AI assistant trained on your menuConversational guidance for goals, swaps, and questions. Grounded in the dishes you actually serve, not a generic database.
  • Workouts & treatments inlineThe same app shows that day's classes and available massage slots. One place, not three apps.
  • Works offlineBy the pool, in the gym, in a Wi-Fi dead zone — logs queue locally and sync when back online.

Pricing

Simple. Tied to actual usage.

You only pay for guests who actually use the app during their stay. No per-seat licenses. No surprises.

Per-guest pricing
€1
per active guest, per day

Charged only on days a guest actually logs activity during their stay. A 14-day guest who uses the app from arrival to checkout costs you €14. On a typical €800 weekly package, that's under 2% of revenue.

  • Unlimited guests, trainers, and admins
  • Unlimited menu items, workouts, and treatments
  • AI meal plans and AI-assisted menu management
  • 5 languages out of the box
  • iOS native shell and PWA install
  • Sentry, BetterStack, and PostHog observability
Book a demo to see it live
Optional setup and base fee may apply depending on rollout scope (POS integration, branded domain, locale additions). We discuss this transparently on the demo call — the per-guest rate is the only number that scales with your business.

In return, you keep a direct channel to that guest after they leave, instrument every coaching session, and capture data on what's actually working in your gym — for less than the cost of one round of drinks at the bar.
Why FitKoh

Purpose-built for the way your gym actually runs.

Generic fitness apps weren't designed for guests who arrive Monday and leave Sunday. Paper forms and trainer spreadsheets weren't either.

The status quo
  • Paper waivers and intake forms scanned to a shared drive.
  • Trainers tracking 5 to 8 clients on whiteboards or Notion docs.
  • Generic calorie apps with food databases that have nothing to do with your kitchen.
  • Marketing emails after checkout that go to people who haven't opened the app since.
  • No data on which dishes, classes, or trainers actually retain guests.
FitKoh
  • Digital waiver and onboarding captured in the same chat that sets the guest's goals.
  • One trainer dashboard for the whole roster, with edit-on-behalf for sessions.
  • Macros and meal plans built from your dishes, including AI image generation for new items.
  • Same app stays installed after checkout — no rebuilding the relationship.
  • Every meal log, workout, and trainer action flows into your data warehouse.
Competitor research

What works for gym software leaders.

Mindbody, TeamUp, and Zen Planner consistently win on one thing: they promise one operating system for bookings, billing, and communication. This table maps where FitKoh is strongest today and where product gaps still exist.

  • Mindbody works because: it leads with all-in-one operations + marketplace demand generation.
  • TeamUp works because: it sells simplicity for memberships, class bookings, and automated comms.
  • Zen Planner works because: it focuses on owner outcomes (time saved, retention, billing reliability).

For people who care about every calorie

Log meals from the real menu. Not a generic database.

Stop guessing whether pad thai from the hotel kitchen matches some random chain restaurant entry. FitKoh is built for gyms and retreats where your food is served from their kitchen — so macros, meal plans, and one-tap logging match what is actually on the plate.

  • Daily calorie and macro targets that stay visible all day
  • AI meal plans built only from dishes your gym lists
  • Chat help for swaps and questions, grounded in that menu
  • Works offline when Wi-Fi drops

Access is through your gym: they issue an invite code or link. FitKoh is not a separate consumer subscription — it is the same app the gym uses for every guest.

Why most trackers fail you

Weight loss is hard enough without wrong calories.

Research on dietary self-monitoring shows that consistent logging predicts success — but people quit when entry takes too long or numbers feel fake. Generic apps force you to pick "closest match" meals that are not your chef's recipe.

What meal-focused users want

  • Truthful macros for this kitchen, not an average
  • Fast logging so the habit survives busy days
  • A clear daily budget (calories + protein) they can trust
  • Guidance when social eating gets messy — chat that knows the menu
Your day

Three taps. No detective work.

Open menu → pick the dish you actually ate → adjust portion. Your running totals update instantly. Optional AI-generated day plan keeps you inside targets without spreadsheet math.

Morning
Targets already set
Profile + goals drive calorie and macro targets. You see what's left for the day at a glance.
Meals

Every item ties to the gym's menu — the same names you see on the board.
Evening

Chat asks questions in context. Meal plan tab lines up tomorrow's plates from real options.
Competitor research

What top meal apps do really well.

Cal AI, Cronometer, and MyFitnessPal all remove logging friction with quick input and strong trust signals. FitKoh borrows the speed patterns but anchors data to the gym's real menu.

  • Cal AI works because: photo-first logging feels instant and low effort.
  • Cronometer works because: users trust its accuracy and nutrient depth.
  • MyFitnessPal works because: huge database + simple daily habit loop.

Research note: consumer-first competitors win on open signup; FitKoh currently wins on gym-specific meal truth.

Get the code from your gym.

When your retreat or gym runs FitKoh, nutrition tracking becomes stupidly simple — because the app was built around their menu, not the internet's.

For people who train on a real timetable

Your week's classes and logs in one place.

Pick today's workout from the schedule your gym maintains — group classes, PT blocks, hikes — and log it on your timeline next to meals and notes. No more juggling a workout app, a chat thread, and a meal tracker that do not talk to each other.

  • Workouts filtered by day and time slot
  • Same-day timeline: food, workouts, body metrics, notes
  • Optional treatments (e.g. massage) on the same calendar mindset
  • Offline-friendly when the gym Wi-Fi cuts out

Your gym enables access with an invite. Trainers can also log strength work on your behalf during a session when they have permission.

What workout trackers actually want

Adherence beats novelty.

Studies on exercise tracking highlight consistency and feedback as key motivators. You need to see what you did this week, not hunt through five apps. FitKoh aligns workouts with the schedule the gym publishes — so "what should I do today?" is answered inside the same app you already use for food.

Where FitKoh fits

  • Pick from scheduled sessions instead of free-text guesswork
  • Keep resistance and conditioning next to nutrition data
  • Let your coach correct or add a session during a PT hour
Tracking

One timeline. Everything that mattered today.

Your day view rolls meals, workouts, notes, and metrics into a single scroll — the same story your trainer sees when you grant access.

Competitor research

What workout tracking winners nail.

Workout-focused apps and coaching platforms win by making adherence visible and reducing admin. FitKoh's edge is connecting class schedule + workout + meal in one timeline.

  • Trainerize works because: clients stay engaged with workouts, habits, and messaging in one app.
  • TrueCoach works because: coaches can quickly monitor compliance and adjust plans.
  • Everfit works because: automation and communication scale one-to-many coaching.

Train where your gym runs FitKoh.

Ask reception or your coach for an invite. Once you are in, your training week and your nutrition finally share one home screen.

For coaches tired of screenshots

See every client in one roster.

Your clients already eat at the gym's restaurant and train on its timetable. FitKoh gives you a live feed of meals, workouts, body metrics, and notes — plus edit-on-behalf when you are standing next to them. WhatsApp one tap when you need a human conversation.

  • Assigned clients sorted by recency and activity
  • Read-only timeline with optional coaching edits
  • 6-digit share codes and QR: clients stay in control
  • Staff roles enforced in the app (no accidental leaks)

FitKoh is deployed per gym. Pricing is arranged with the owner — your talking point is less admin and clearer compliance, not a second subscription for each coach.

What trainers told us they need

Proof of adherence without chasing screenshots.

Personal trainers juggle compliance checks, programming notes, and endless DMs. They want one trusted stream that proves what the client ate and how they trained — tied to the real facility, not self-reported totals from random apps.

FitKoh delivers

  • Open a client to the same day timeline they see
  • Log meals or workouts for them when you are side-by-side
  • Message via WhatsApp using pre-filled context
Permissions

Clients invite you. Not the other way around.

They generate a code or QR. You redeem once. If they revoke access, your roster updates — clean boundaries for boutique gyms and retreats.

Competitor research

What high-performing trainer platforms prove.

Trainerize, TrueCoach, and Everfit consistently win with client management speed, communication, and scalability. FitKoh differentiates when trainers operate inside a gym-retreat environment with shared menus and schedules.

  • Trainerize works because: it bundles training, nutrition, and client engagement in one place.
  • TrueCoach works because: compliance tracking and program delivery are fast and clear.
  • Everfit works because: automation and workflows make larger client books manageable.

Research note: this makes the strategic tradeoff explicit - FitKoh is gym-context first, not solo-trainer SaaS first.

Bring FitKoh to your gym.

We help owners roll out invites, trainer roles, and schedules. You focus on coaching — not stitching spreadsheets.
