Zanda (Formerly Power Diary) Alternative: Do You Need Practice Management or a Simpler Website + Booking + CRM System?
Power Diary is now Zanda. Compare Zanda with OneStudio to decide whether you need allied-health practice management or a simpler website, booking and client workflow.
Overview
If you are searching for a “Power Diary alternative” in 2026, start with one update: Power Diary is now Zanda.
The company rebranded in November 2024. The platform continued under the new name and has kept expanding its health-practice features.
That matters because old comparison pages can make the product look like a scheduling diary. Current Zanda is much broader: client portal, forms, waitlists, telehealth, billing, insurance-oriented workflows, clinical records and practice operations all sit around the calendar.
OneStudio therefore is not a like-for-like Zanda replacement for a clinical practice. It becomes relevant only when the business needs a simpler public website, appointment schedule and ordinary client record.
First, translate the old search query
These searches now belong to the same buying decision:
Do not evaluate a product against the 2023 or early-2024 version of Power Diary. The current platform and brand are Zanda.

Why Zanda is difficult to replace with a general business platform
The portal is part of operations
Zanda’s client portal can expose bookings, invoices, forms and waitlist requests. Current 2026 updates expanded branding, forms and self-service.
A basic booking page does not replace that portal.
The record can be clinical
Zanda is aimed at allied-health and mental-health practices. Its feature set includes notes, forms and healthcare-oriented records.
That is a different data model from OneStudio’s service-business client card.
Telehealth connects to the practice workflow
Zanda currently supports virtual appointments through a Zoom-based workflow. Its older WebRTC Telehealth Lite/Plus services were retired. OneStudio does not currently document clinical video care.
Billing is deeper than payment status
OneStudio can keep payment status connected to bookings where enabled. Zanda can support a broader practice-billing context, including insurance-oriented features.
If your team depends on those functions, compare Zanda with other health-practice platforms.
When OneStudio becomes a relevant alternative
You do not need a health-practice record
The strongest fit is a non-clinical appointment business that adopted Power Diary years ago for scheduling but never needed healthcare functionality.
Your website is becoming the center of acquisition
OneStudio combines:
For a local service business, that can be a more natural center of gravity than a client portal.
- pages;
- visual editing;
- media;
- service information;
- online booking;
- client records;
- operational history.
Your booking model is straightforward
OneStudio works from services, working windows and staff/resources where configured.
If your appointments do not require clinical forms, complex healthcare billing or longitudinal care records, the simpler model can be enough.
You want fewer systems
OneStudio’s public product model is designed to connect the website to booking, client history, payment status and reminders.
That can reduce tool sprawl for a small service business.
Who should keep Zanda
Keep Zanda, or compare it with another clinical practice platform, if you need any of the following:
These are not edge features. They define the software category.
- health records;
- clinical notes;
- healthcare intake forms;
- secure client portal;
- telehealth;
- insurance claims or related billing;
- clinical document storage;
- healthcare-specific privacy/compliance;
- advanced allied-health practice management.
A migration framework for former Power Diary users
Step 1: update your mental model
Do not evaluate “old Power Diary” against new software. Review what Zanda currently does in your account.
The rebrand did not turn the product into something smaller; it reflects that the platform grew beyond a diary.
Step 2: classify every workflow
Use four columns:
OneStudio can be compared for the first two columns and ordinary service payment workflows. It should not be assumed to replace the latter two.
Step 3: decide whether the portal is essential
If clients regularly upload documents, complete forms, review invoices or manage healthcare-related information through the portal, replacing it is a separate project.
Step 4: test public booking
If you move to OneStudio for a non-clinical business, test the entire path:
- service page;
- booking CTA;
- service selection;
- available time;
- staff/resource if relevant;
- contact details;
- booking record;
- linked client;
- payment/reminder behavior if enabled.
Step 5: preserve history safely
A replatforming project does not erase legal or professional retention requirements. Keep clinical and sensitive records in an appropriate system.
| Workflow | Marketing | Booking/operations | Clinical | Finance/compliance |
|---|---|---|---|---|
| Service pages | ✓ | |||
| Appointment availability | ✓ | |||
| Clinical notes | ✓ | |||
| Client portal forms | ✓ | ✓ | ||
| Payment status | ✓ | ✓ | ||
| Insurance claims | ✓ |
Example: counsellor vs non-clinical consultant
Counselling practice
The team uses notes, secure forms, telehealth, client portal and health-practice billing.
Zanda is performing clinical operations. OneStudio is not a replacement for that system.
Non-clinical consulting studio
Clients read service pages, choose a consultation type, select an available time, receive reminders and return later. The business only needs ordinary contact information and booking notes.
OneStudio can be a more natural fit because the website and appointment workflow are the central problem.
Price is not the right first filter
Current comparison SERPs make it easy to sort platforms by monthly price.
That can be misleading.
A cheaper website/booking platform is not cheaper if you then need separate tools for:
A full practice platform is not better value if your business never uses those functions.
Normalize the workflow before comparing price.
- clinical records;
- secure forms;
- telehealth;
- portal;
- insurance workflows.
Questions for any Zanda / Power Diary alternative
Does it handle the data I am legally required to keep?
This comes before UI preference.
Does it support my actual booking rules?
Test service length, provider, location, resource, working hours, reminders and payments.
What does the client see?
Compare the public website, booking flow and portal separately.
Which system becomes the source of truth?
Avoid keeping partial client histories in multiple places without a clear owner.
Can I leave without losing access to required history?
Plan exports, retention and access before cancellation.
The bottom line
In 2026, “Power Diary alternative” means “Zanda alternative.”
If you need allied-health practice management, compare Zanda with other health-practice systems.
If you no longer need the clinical layer and your business is fundamentally website → booking → client, compare OneStudio online booking, CRM and current pricing.

Power Diary rebranded as Zanda in November 2024. Current product and support materials use the Zanda brand, with redirects from older Power Diary links.
Is OneStudio a Zanda alternative for therapists or allied-health clinics?
Not as a clinical practice-management system. OneStudio does not document EHR/clinical records, telehealth, healthcare portal, forms or insurance workflows comparable to Zanda.
Can OneStudio replace Zanda for a non-clinical appointment business?
Potentially, if the business only needs a website, standard service booking, client history, payment status and reminders. Test the specific scheduling model first.
Does OneStudio include a website?
Yes. The Site plan includes a website and visual editor; Business adds online booking, schedule, CRM/client base, payments/deposits and reminders.
