Built for mental health

Zanda Health Alternative for UK Therapists

Therasee is a specialist platform for therapists and counsellors, not adapted from broader allied health.

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.

AI form builder, not just intake templates

Therasee’s form builder includes an AI assistant that builds forms from plain English, 50+ validated assessments built in (PHQ-9, GAD-7, CORE-OM, PCL-5), and PDF-to-form conversion that turns paper forms into editable digital documents. Zanda Health offers an intake form template library with signature collection, but no AI assistant, no built-in clinical assessments, and no PDF conversion.

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.

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 e-signatures, payments, messaging, and documents, all from one professional, private space. Zanda offers online booking but not a unified, branded client experience.

Support from people who know your practice

When you reach out to Therasee, you speak to someone who understands your workflow as a therapist. No ticket queues, no chatbots, no waiting days for a reply. Zanda Health is a large platform serving many disciplines, and support reflects that breadth. Therasee’s support is personal, direct, and specific to mental health.

Zanda Health strengths

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.

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.

FAQ

Frequently asked questions about Zanda Health and Therasee

Is Zanda Health the same as Power Diary?

Yes. Zanda Health was previously called Power Diary. The Australian company rebranded but the platform’s audience and feature set remained the same: a generalist allied health platform serving physiotherapists, chiropractors, psychologists, massage therapists, and other disciplines.

Is Zanda Health based in the UK?

No. Zanda Health (formerly Power Diary) is based in Australia. Pricing is in USD and the platform follows Australian and US conventions in many of its defaults. Therasee is UK-based, hosts data in UK data centres, prices in GBP, and is built specifically around UK practice norms.

Does Zanda Health include video sessions?

Zanda offers video via a Zoom integration rather than built-in video. Unlimited video calls require a $9 per month add-on per practitioner on top of your plan. Therasee includes unlimited, end-to-end encrypted HD video on all paid plans at no extra cost, or you can bring your own Zoom, Meet, or Teams link.

Does Zanda Health have a free plan?

No. Zanda Health offers a 14-day free trial, then plans start at $19 per month (Starter, with a 1,000 appointment cap). Therasee has a permanent free plan (£0 forever) with 3 clients and full features, and Premium is £19 per user per month with no caps.

Is Zanda Health built for therapists?

Zanda Health was founded by a psychologist and is widely used by therapists, but it’s a generalist platform serving the full allied health sector. Features like body charts, Physitrack exercise programmes, and multi-discipline scheduling are built into the experience. Therasee is mental-health-only, with templates, prompts, and workflows designed specifically for therapy practice.

Should I choose Zanda Health or Therasee?

Choose Zanda Health if you run a multi-discipline health practice that includes physical therapy services, you need ISO 27001 certification, or you want integrations like Xero and Physitrack. Choose Therasee if you want a UK-native, mental-health-specific platform with GBP pricing, GDPR-first design, and everything included at one price.
