Personal Training Scheduling Software for 1-on-1 Sessions.
"Same time Thursday?" isn't a booking system.
Personal training, fitness assessments, nutrition consultations: with Slotara, your clients book their appointments themselves — with the trainer they want, from that person's real weekly schedule, within the time windows you release. The slot is blocked instantly.
Appointments made in passing fall through in passing
Your sessions are in the calendar. But how they get there has little to do with a calendar.
The problem isn't your commitment. The problem is that your scheduling happens exactly when you're supposed to be training.
After the session.
"Same time Thursday?" — "Should work." Two weeks later, two people are standing on the gym floor for the same slot, and one of them rightly so.
The WhatsApp at 9:48 pm.
"Hi, anything free this week?" — on your private number, between closing time and family. You'll answer tomorrow. Maybe.
The note at the front desk.
"Ms M. would like an assessment, please call back." Who calls back, when, and whether the appointment is still needed by then — the note doesn't say.
Your clients book themselves — you train
A booking link on the gym website, a QR code at the front desk, or shared straight in a chat — and scheduling stops happening in passing.
-
1
Choose a service. 1-on-1 training, assessment or consultation — every service appears with its duration in the booking.
-
2
Choose a person and a time. Clients pick the trainer they want — or simply the next free appointment. What's shown is that person's real availability, calculated from their weekly schedule, their appointments and their buffers.
-
3
Even at night, when nobody's at the desk. Booking runs around the clock — exactly when your clients plan their week. They book from the time windows your team has released, including an early slot in the days ahead.

4
Blocked instantly. With the booking, the slot is occupied in the calendar — no double allocation, no "but we agreed verbally". The confirmation goes out automatically.
Open slots nobody can see stay open
Demand follows the familiar name: one calendar is packed for weeks while good times sit empty with a colleague — not because she trains worse, but because her availability is visible nowhere. In Slotara, every person on the team has their own weekly schedule, and booking shows real open times per person. Whoever isn't looking for a specific name sees the next free appointment — which is often with exactly the person who has capacity.
Weekly schedules can look the way your day actually does: an early block before your clients' workday, a midday break, an evening block after — multiple working windows per day, different per person. Holidays and trainings go in as absences; those times disappear from booking.
Multiple working windows per day, different per person — booking knows them all.
Booking respects who offers what
Nutrition consultations belong to the people with the consulting qualification, the 1-on-1 yoga session to those with the training. In Slotara you define the required qualification per service — and it can only be booked with team members who meet it. No awkward rebookings, no sessions with the wrong profile: the mapping lives in the system, not in someone's head at the front desk.
A clear run-up to every appointment — and transparency when someone doesn't show
Early and late slots are the most sought-after asset in the gym — and the hardest to refill when they fall through. Slotara makes the run-up to every appointment clear, without you chasing anyone afterwards.
-
1
Confirmation with calendar entry. Every booking is confirmed immediately — with an .ics attachment for your client's calendar.
-
2
One reminder, your timing. Before the appointment, Slotara reminds exactly once by email, with the lead time you set (default: 24 hours).
-
3
Cancelling with a deadline. Up to your deadline, the appointment can be cancelled self-service. After that, the self-service cancellation window ends. A slot cancelled in time becomes bookable again immediately.
-
4
When someone doesn't show. You mark missed sessions as such and see them in your reporting — you learn where appointments fall through instead of guessing.
Start with a prepared training template
You don't start from zero: the template ships with typical one-on-one services including duration and buffers — from the 30-minute session to the nutrition consultation — plus matching qualifications and a weekly schedule across long gym hours. Everything is a starting point, nothing is fixed: you adapt services, times and assignments to your business instead of inventing them from scratch.
What Slotara is in your gym — and what it isn't
Slotara organises the appointment-based services in your business: 1-on-1 training, assessments, consultations. Memberships, contracts, check-in and your class schedule stay in your gym software — Slotara doesn't replace them and doesn't want to.
More than one gym? Locations with their own team stay in one Slotara environment — depending on your plan.

Common questions from gyms and personal trainers
No. Slotara is built for one-on-one appointments — personal training, fitness assessments, nutrition consultations. Class and attendee management is not part of the product.
No. Memberships, contracts and check-in stay in your gym software. Slotara organises the bookable appointment services alongside it — with its own booking link and its own calendar.
Every person gets their qualifications on file, and services require the matching qualification — a service can only be booked with team members who meet it.
Booking, yes — any time. What can be booked are the times within your team's weekly schedules, including multiple windows per day (early and evening, for instance). What's shown is real availability.
The slot is blocked instantly and the confirmation goes out by email — with a calendar entry (.ics). Before the appointment, Slotara reminds exactly once, with the lead time you set.
Up to your deadline, the appointment can be cancelled self-service. After that, the self-service cancellation window ends. A slot cancelled in time becomes bookable again immediately.
