For gyms
Gym management software that knows who's paid up.
A gym doesn't live on the session, it lives on the membership. Siimplo tracks each member's dues month by month, prompts before they lapse, and shows who stopped coming before they cancel.

The business is the membership, not the session
A class studio bills for what it teaches. A gym bills a membership: it charges at the start of the month, people come when they like, and revenue depends on how many renew rather than how many showed up on Tuesday.
That moves where the problem sits. It isn't filling a class grid — it's knowing, on any day of the month, who's current, whose membership lapses this week, and who is two months behind while still training.
On a spreadsheet you learn that at month end, which is too late. Siimplo carries each member's dues as a dated status — current, due soon, overdue — so the answer is one screen rather than a monthly review someone has to remember to run.
The member who stops coming warns you before they leave
Nobody cancels a gym membership suddenly. First they miss a week, then two, then they stop paying. Six or eight weeks pass between the first symptom and the cancellation, and almost no gym sees them go by.
With visits and dues recorded, the list of members who are paying but no longer showing up writes itself. It's the most profitable list a gym owns: people who already chose you, who are still paying, and who are one conversation away from renewing instead of leaving.
And because prompts go out over WhatsApp, the renewal reminder lands without anyone assembling a broadcast list every month.
And classes, when you run them too
Almost every gym has some class element: functional, spin, a couple of assisted-training slots. It isn't the main business, but it needs the most coordination, because it has capacity and a time.
Classes with capacity are scheduled like any other service and members book from your site. When a slot is full it stops being offered. If you also sell session packs for personal training, they count down exactly as they would in a studio.
It's the same platform class studios run on, so if the mix shifts — more classes, less floor — you don't change systems.

Ryo, the AI assistant

Reports
Revenue, expenses and net profit for any date range, with a trend chart, a category breakdown and a downloadable report.
Session Packs
Sell blocks of 5 or 10 sessions and let the system burn down credits automatically — the way personal training actually sells.
Front Desk

Live Waiting Room
Today's appointments on one side, who has arrived on the other — call the next one in with a single click.

Your staff roster with roles, last activity and access toggles, plus a permissions tab as the business grows.
