A missed session is an hour you can't sell twice. Remindlo texts clients before every booking and members before their renewal, working on top of the calendar or member list you already keep - with no data entry.

The Hidden Cost of Empty Slots
Almost nobody quits on purpose. They forget a session, let a block of PT expire, miss a renewal date, and drift away.
An Empty Slot Is Gone For Good
A client who forgets a 6am session costs you the whole hour. You can't resell it, and you rarely hear in time to try.
£30-60 Lost Per Lapse
Every member who doesn't renew is recurring revenue walking out the door. Multiply by dozens each month.
PT Sessions Expire Unused
Members buy packages then forget to book. Sessions expire, members feel cheated, trainers lose income.
Why the earliest and latest sessions are the ones you lose →
What This Means for Your Business
Automatic Reminders That Fill Your Diary
Text clients before every booked session, and members before their membership expires. Fewer empty slots. Fewer lapses.
Session Reminders
7 days and 1 day before each booking. The week-out text still leaves time to move a session rather than miss it.
Membership Renewal Reminders
14, 7, and 3 days before expiry. Catch members before they accidentally lapse.
PT & Class Pack Alerts
Tell clients when their sessions or prepaid credits are running low, before they quietly expire.
One-Click Renewals
Include your renewal link. Members tap once and they're renewed.

Watch Your Diary Fill
Reminders go out automatically. Clients turn up. Members renew.
Still tracking sign-ups on paper? Just take a photo
No gym-system export or spreadsheet handy? Snap a photo of your sign-up sheet or PT booking book and Remindlo reads the names, numbers, and dates for you - about 30 seconds instead of an hour of typing.

What Remindlo users say
“Easy to install and setup new campaigns for small and medium businesses. Free up to 10 SMS per month so you can try without worrying about the bill.”
“I run a small biz and that plugin saves me a ton of time. Works in the background, since I also enabled the auto-sync option. No extra work for me, events with phone numbers are picked up automatically for the reminders; I'm already busy with other stuff so that's good. Using two out of three default workflows - per-visit reminders and post-visit thank you notes to collect reviews.”
