Therasee vs Zanda Health
Specialist vs Generalist for Your Therapy Practice
Zanda Health (formerly Power Diary) is an established practice management platform used by over 40,000 practitioners across 23+ countries. Founded in Australia in 2010 by psychologist Damien Adler, it serves a wide range of allied health professionals,from physiotherapists and chiropractors to psychologists and counsellors.
Zanda is well-built, competitively priced, and holds ISO 27001 certification. But as a generalist platform, its features are designed for the broadest possible range of health practitioners. If you’re a mental health professional in the UK, you may find yourself navigating body charts, Physitrack integrations, and features designed for physical health clinics,rather than using a tool built specifically for the way you work.

Where Therasee stands out
Made for mental health, not adapted for it
Zanda Health serves physiotherapists, chiropractors, massage therapists, and many more. That breadth means features like body charts, Physitrack exercise programmes, and multi-discipline scheduling are built into the experience. Therasee was designed from day one for the specific workflows of mental health practitioners,therapy-specific note templates, session-linked documentation, and a client portal built around the therapeutic relationship.
Built-in video, no add-ons
Therasee’s secure video is built in, unlimited, and end-to-end encrypted at no extra cost. Zanda Health relies on a Zoom integration, and unlimited video calls require a $9/month add-on per practitioner on top of your plan.
Rich, secure messaging
Therasee includes a full in-app messaging system where you can send forms in conversation, use reusable templates, share files, and dictate messages with speech-to-text. Clients get push notifications from the branded portal. Zanda Health offers SMS reminders and two-way SMS at additional cost, but doesn’t provide in-app messaging between sessions.
UK-native platform
Zanda Health is Australian and prices in USD by default. Therasee is registered in England, charges in GBP, and was built around UK regulatory and professional frameworks.
A client portal that feels like yours
Therasee’s portal carries your branding, installs as a mobile app, and gives clients self-service access to booking, forms with digital signatures, payments, messaging, and documents,all from one professional, private space. Zanda offers online booking but not a unified, branded client experience.
Where Zanda Health stands out
ISO 27001 certification
Zanda Health holds ISO 27001 certification,the international standard for information security management. Combined with HIPAA and GDPR compliance, this is a meaningful credential for practices with strict compliance requirements.
Established track record
With over 14 years of development (originally as Power Diary) and 40,000+ users across 23 countries, Zanda Health is a mature platform. That longevity brings stability, a well-documented feature set, and an established support ecosystem.
BizzyAI transcription
Zanda’s BizzyAI feature offers AI-powered session transcription and clinical note generation,a genuinely useful capability for practitioners who want to automate documentation beyond speech-to-text dictation.
Wider integration network
Zanda integrates with Xero, Zoom, Physitrack, Mailchimp, and more. If your practice relies on specific third-party accounting or exercise prescription tools, Zanda’s integration network is currently more extensive.
