Fill the Gap · PILOT 2026

Personal training today.

GapApp connects people who want to train with available personal trainers.

01 · PROBLEM

Availability exists on both sides. What’s missing is a simple way to connect.

A free slot can open up suddenly. So can the urge to train. What’s missing today is a simple way to bring those two moments together.

I’m a trainer

A session gets cancelled or a slot suddenly opens up in your schedule? Show your availability to people looking for a workout.

I want to train

Got time to train today? Instead of messaging trainer after trainer to ask about availability, see who’s free.

02 · HOW IT WORKS

How does GapApp work?

From an open slot to a workout.

  1. 01

    The trainer shares their availability

    They add the time, location and type of training.

  2. 02

    You check available trainers

    See who has an open slot.

  3. 03

    Choose a workout

    No searching through profiles or messaging trainer after trainer to check availability.

  4. 04

    Meet for your workout

    An open slot and the desire to train meet in one place.

A trainer has an open slot. You have time. GapApp connects you now.

Transcript (Polish)

Odwołany trening w ostatniej chwili? Pusta godzina w grafiku to utracony przychód.

Chcesz trenować dzisiaj, ale nie możesz planować z wyprzedzeniem?

Nie czekaj na termin za kilka dni. Trener ma wolną godzinę.

Ktoś właśnie chce trenować. A jednak wciąż się mijają.

GapApp sprawia, że te dwa momenty wreszcie się spotykają. Tu. Teraz. W czasie rzeczywistym. Wolny termin? Wrzuć go w kilku prostych krokach do GapApp. Ty decydujesz: kiedy, gdzie i za ile. Chcesz trenować teraz?

Widzisz treningi, które naprawdę są dostępne. Wybierasz: gdzie, kiedy i z kim. W dodatku w niższej cenie. GapApp pokazuje wolne treningi osobom gotowym skorzystać z nich tu i teraz. Widzisz. Wybierasz. Rezerwujesz.

Kilka chwil wcześniej była luka. Teraz jest trening.

GapApp to więcej niż wolne terminy. To społeczność trenerów i ludzi, którzy chcą być aktywni wtedy, kiedy naprawdę mogą. Więcej dostępnych treningów. Mniej „może innym razem”. Mniej wolnych godzin, więcej nowych klientów.
