The short version
- Each has a real cost: Signant Health no pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.; Zanda Health the 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
- They diverge on capability: Signant Health covers eCOA and ePRO, Zanda Health covers Unlimited admin users.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Signant Health
- No pricing is published, and the software licence is a minority of the real bill once instrument licensing, translations, device provisioning and services are added, so early budget estimates are routinely too low.
- Linguistic validation is charged per instrument per language and is on the critical path to first patient in, so adding a country late in start-up produces both a cost and a schedule hit.
- Provisioned participant devices bring logistics, replacement, shipping and cellular connectivity obligations that persist for the life of the trial and are frequently underestimated.
- The EDC component is newer than the eCOA heritage, so sponsors with complex data management requirements often keep an incumbent EDC and lose the single-database benefit that justifies the platform.
- It is priced and scoped for sponsor-grade trials, which makes it a poor fit for investigator-initiated or academic studies that need outcome collection without the services layer.
Zanda Health
- The 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
- North American billing is not properly served: there is no claims clearinghouse and superbill handling is basic, so a United States practice will need a separate revenue cycle tool and will pay for two systems.
- Pricing is quoted in United States dollars while the company, support hours and product depth are Australian, so buyers outside those two time zones get support with an overnight lag on urgent clinical scheduling problems.
- SMS is billed per message beyond the plan allowance and a dedicated number is required in the United States and Canada, so a busy clinic sending reminders and follow ups accumulates a variable monthly cost that is not visible in the headline plan price.
- Reporting is adequate for a single clinic but weak for a group: cross site financial consolidation and practitioner productivity comparison generally end up exported to a spreadsheet, which becomes a monthly manual job as soon as you pass a handful of locations.

Answered from the vendors’ own pages
Signant Health: What is Signant best at?
Electronic clinical outcome assessment, particularly rated scales in central nervous system and psychiatry trials, together with rater training and endpoint quality services.
Zanda Health: Is Zanda Health the same as Power Diary?
Yes. Power Diary rebranded to Zanda Health in 2024. Same company, same product line, same data.
Signant Health: Is pricing published?
No. Everything is quoted per study, and instrument licences, translations and devices sit on top of the platform cost.
Zanda Health: Do receptionists count as paid users?
No. On the Growth plan administrative users are unlimited and free. Only practitioners are charged.
Signant Health: Can I use it only for eCOA?
Yes. The modules are selected per protocol, and many sponsors take eCOA and eConsent while keeping an existing EDC.
Zanda Health: Does it handle Medicare bulk billing?
Yes, Medicare Online, DVA and bulk billing claims are submitted from within the platform for Australian practices.
Signant Health: What drives the timeline?
Translation and linguistic validation of outcome instruments, which is per language per instrument and sits on the critical path to study start.
Zanda Health: Is it suitable for a United States practice?
Only partly. Charting, scheduling and telehealth work, but there is no claims clearinghouse, so US insurance billing needs a separate system.
