iSplash is an actively-marketed swim-school management platform. ClassBase is a configurable activity engine that runs any activity's admin the same way — plus private venue hire that turns your off-peak hours into hands-off revenue, one flat monthly price with no per-swimmer fee, and GoCardless bank Direct Debit.

About this comparison: points about iSplash below come from publicly available information — isplash.uk, its Capterra and GetApp listings, and STA's own partner page — accurate as of August 2026. Both platforms develop continually, so figures may change — please check iSplash's current pricing directly for the latest. This page describes what ClassBase does; it does not claim iSplash lacks any feature we haven't verified.
Both platforms handle bookings, waiting lists and a parent portal well, and both support GoCardless. Whatever you teach, these two stand out — and both are drawn straight from iSplash's own published information.
iSplash prices per swimmer: £90/month for up to 250 active swimmers, then plus £18/month for every additional 50. ClassBase is a flat monthly tier — £25, £49 or £79 — with no per-swimmer fee at all. Grow your roll from 100 to 400 swimmers and an iSplash bill grows with it; a ClassBase bill doesn't move.

iSplash markets itself specifically as swim-school management software. ClassBase is a configurable activity engine — the same bookings, payments, registers and waiting-list tools run swim, dance, gymnastics, football and more, plus private venue hire that turns off-peak hours into hands-off revenue on the same platform.

Where they match, we say so — including a payment rail both platforms share. Where they differ, it's drawn from public information.

A dash (—) means we haven't verified that feature in iSplash's public materials either way — not that it's absent. The rows show what ClassBase provides.
A configurable activity engine with the depth a serious operator needs — whatever mix of activities you run.
Bookings, payments, registers, waiting lists and parent messages work the same whatever you teach — swim, dance, gymnastics, football and more. Add the skills framework that fits each class, including Swim England and STA for swim.
Rent your space out when it would otherwise sit empty — pool lanes, a dance studio, a sports hall or a court. Customers book and pay online and get their access code automatically, so it runs completely hands-off: an extra revenue stream on the same platform as your classes.
Collect termly or monthly fees by bank Direct Debit or card, with a waiting list that triggers mandate setup automatically when a place is offered.
Starter £25, Pro £49, Enterprise £79 per month +VAT. No per-swimmer fee — the price is the price whether you have 50 swimmers or 500.
The import wizard auto-detects SwimBiz exports and brings customers, classes, attendance and waiting lists across — most schools are live within the hour.
Swim England, STA and custom frameworks marked poolside on any device, visible to parents through the portal — plus frameworks for any other activity you run. Depth without being locked to one sport.
A fair comparison cuts both ways. iSplash is a dedicated, swim-school-specific product — it markets itself around swim schools alone, is an STA partner with a member discount, and bundles STA Digital Awards directly in-app, alongside its own iSplashPay Direct Debit rail on top of GoCardless and Stripe. If you only ever run swim classes and want a specialist tool with those specifics already built in, that's a genuine point in iSplash's favour.
ClassBase's bet is different: run any activity — swim, dance, gymnastics, football and more — on one calm platform, priced flat with no per-swimmer fee, with private venue hire turning your off-peak hours into hands-off revenue, and swim support (Swim England & STA) deep enough that swim-only schools don't lose anything by choosing the broader engine.
Yes. iSplash is an actively-marketed swim-school management platform, and ClassBase is a configurable activity engine — bookings, payments, registers, waiting lists and parent messages work the same whatever you teach, and you add the skills framework that fits each class. It also includes private venue hire that turns your off-peak hours into hands-off revenue, all on a flat monthly tier with no per-swimmer fee and GoCardless bank Direct Debit — the same rail iSplash itself supports. Both offer a free trial, an online waiting list and a parent portal.
iSplash publishes usage-based pricing: £90/month for up to 250 active swimmers, plus £18/month for each additional 50 swimmers, with no setup fee but a data-migration fee (isplash.uk, Capterra, GetApp). ClassBase is a flat monthly tier — Starter £25, Pro £49 or Enterprise £79 — with no per-swimmer fee at all, so the price stays the same as your roll grows.
Not currently. ClassBase runs as a responsive web app that works on any phone, tablet or computer, with a dedicated teacher view for poolside registers and progress. We haven't verified whether iSplash ships a native app, so this page makes no claim either way — check iSplash's own site for its current app support.
No. iSplash markets itself specifically as swim-school management software. ClassBase is a configurable activity engine used for swim, dance, gymnastics, football and more — the same bookings, payments, registers and waiting-list tools apply whatever you teach, and you add the skills framework that fits each class, including Swim England and STA progress tracking for swim schools.
Yes. ClassBase's import wizard auto-detects SwimBiz exports and brings customers, classes, attendance and waiting lists across, and accepts CSV exports from other systems. Most schools are running within the hour.
Export your customer and student list from iSplash as CSV. ClassBase imports your customers, students and class assignments, so you're not starting from zero.
Configure your timetable, pricing and payment methods. Most schools finish this in a single session — and you can start a free trial to try it first.
Invite parents to the portal. They log in, see their child's classes, and manage bookings and payments from day one.
