Stay In Shape vs PTminder: 2026 Comparison

PTminder does not have Trainerize's global brand recognition, but it has built a loyal following among independent trainers — especially in the UK and Australia — for its straightforward scheduling and clean client portal. If you are weighing PTminder against a newer alternative, here is an honest look at what each platform actually delivers.

Stay In Shape Overview

Stay In Shape is a SaaS platform launched in beta in 2025, designed for independent personal trainers. Its key differentiator is combining AI-native program generation and analysis with full business management — scheduling, client portal, nutrition tracking, and invoicing — in a single interface.

• AI program generation — builds a structured training program from a client's full profile (goals, medical constraints, available equipment) in seconds;
• AI progress analysis — automatically flags plateaus, gaps between planned and actual sessions, and surfaces adjustment suggestions for the coach;
• GDPR-ready — EU hosting, data processing agreement (DPA) included by default, consent management built into the platform;
• All-in-one — scheduling, client portal, nutrition, and EU-compliant invoicing from €29/month.

PTminder Overview

PTminder was founded in the early 2010s and is most popular in the UK and Australia-Pacific markets. It targets independent personal trainers and small studios with a clean, no-frills approach to business management.

• Advanced scheduling — online booking, automated reminders, recurring sessions, and cancellation management are its strongest suit;
• Client portal — clients can view upcoming sessions, session history, and assigned programs from a dedicated space;
• Integrated payments — online payments via Stripe, package and subscription management;
• Basic CRM — client profiles, notes, session history;
• Business reports — dashboards for revenue, occupancy rate, and client retention.

Where PTminder falls short: no AI features, an interface that feels dated, English-only support, and no documented GDPR compliance path for continental European users. Invoicing is formatted for UK and Australian regulations — not for French or German requirements.

When to Choose Stay In Shape

• You are based in the EU and need invoicing that meets local legal requirements (sequential numbering, mandatory VAT mentions);
• GDPR compliance is a real concern — you handle health data and need a proper data processing agreement in place;
• You want AI to handle program creation and plateau detection so you can focus on coaching, not admin;
• You want scheduling, nutrition, and invoicing under one roof without managing multiple subscriptions;
• You are starting out and want a competitive price with modern tooling from day one.

When to Choose PTminder

• You are comfortable in English and work primarily with an English-speaking client base;
• Scheduling is your top priority and you want a tool that has refined this feature for over a decade;
• You do not need AI and prefer a focused, simple tool without extra layers;
• You run a small studio in the UK or Australia where PTminder's invoicing format already matches your accounting workflow.
