CallidusOS vs Semble
A fair look at CallidusOS and Semble.
A UK private-medical EHR aimed at private GPs, consultants and specialist clinics.
The honest version
Semble (formerly Heydoc) is a strong private-medical EHR. It's clinical-records-first and is widely used by private GPs and specialist clinics. CallidusOS™ takes a broader operating-system approach: EHR is one of ten modules alongside booking, leads, marketing, finance, governance, stock, staff and clinical AI tools.

Where each one shines
Both tools are good. Here is the honest difference.
Where CallidusOS shines
- Full clinic operating system, not just an EHR
- Aesthetics-grade tooling including injection and treatment tracking
- Calia Copilot for dictation, summaries and campaigns Soon
- Built-in marketing, leads CRM and clinic website service
- Purpose-built for UK aesthetic clinics, not a general-purpose EHR
Where Semble shines
- Mature private-medical EHR with strong clinical workflow
- Established in the private GP and specialist market
- Solid integrations with private medical insurers and labs
Being straight with you
Semble might be the better fit if
- You are a pure private GP or specialist clinic and EHR depth is your top priority
- You already integrate Semble with private medical insurance billing flows
- You don't need aesthetics-specific tooling like injection tracking
The right software is the one that fits your clinic. If Semble suits you better, we would rather you chose them than felt boxed in with us in six months. No hard feelings.
