evooia vs PhotoDoc: Reproducibility-First Capture vs a High-Volume Photo Library
evooia and PhotoDoc are both smartphone-native, no-hardware tools, but they optimise for different things. One is built around reproducibility. The other around photo volume and analysis.
TL;DR. evooia and PhotoDoc are both smartphone-native tools with no hardware required. PhotoDoc is a high-volume medical photo platform: framing templates, a manual ghost-photo overlay, AI facial analysis, before-and-after collages, and large photo libraries across iOS, Android, and web. evooia is built around the SAPHIR™ framework, which aligns each capture automatically and stores image, consent, and clinical notes together, with front-camera patient self-capture between visits. Pick PhotoDoc if you need a big, organised photo library with facial analysis. Pick evooia if reproducibility and an integrated clinical record are the priority.
evooia and PhotoDoc both run on the phone or tablet a clinic already owns, with no hardware. The difference is what each one optimises for. PhotoDoc optimises for capturing, organising, and analysing a large volume of patient photos. evooia optimises for reproducibility: every before-and-after pair being directly comparable, with the legal and clinical context attached.

What is evooia?
evooia is a clinical imaging application from a Swiss-based company in the ETH ecosystem. It runs on iPhone and iPad, supports both front and back cameras, and implements SAPHIR™ (Swiss Aesthetic Protocol for High-fidelity Imaging Reproducibility), a framework that keeps lighting, distance, angle, and framing consistent on every capture. Image, consent capture, and clinical notes are stored together and sync to a web dashboard. A patient-side app supports guided remote capture between visits using the front camera. Privacy is built for GDPR and Swiss FADP compliance, and designed to support HIPAA-compliant deployments. Subscription pricing, no hardware required.
What is PhotoDoc?
PhotoDoc is a medical photo platform for healthcare professionals, available on iOS, Android, and the web, with multi-device sync across phone, tablet, and computer. It standardises capture with framing templates and a device-angle sensor, and includes a ghost-photo feature where a faded version of a prior photo is shown so the user can match it before taking the next one. It adds AI facial analysis (horizontal thirds, vertical fifths, eye and mouth ratios) on its higher tier, before-and-after collages with AI filters, secure cloud storage that keeps patient photos out of the device gallery, and biometric or PIN access. Pricing is a monthly subscription tiered by photo volume, from a free trial up to large team plans. It is aimed at professionals who manage a large quantity of patient photos. GDPR, HIPAA, and LGPD compliant.
How are evooia and PhotoDoc different?
Reproducibility method
PhotoDoc's reproducibility relies on framing templates and the ghost-photo overlay, which is a manual matching step: the user lines up the faded prior image by eye before capture. evooia's SAPHIR™ framework removes the manual step, detecting facial geometry and prompting the camera into position automatically, so the same standardised result comes out regardless of who is holding the device.
Workflow scope
PhotoDoc is built around the photo library: capture, organise by category, analyse, and build collages. Consent and clinical notes are not part of its stated workflow. evooia binds image, consent capture, and clinical notes into a single record, so each before-and-after pair carries its own legal and clinical context.
Patient self-capture
PhotoDoc is operated by the professional. evooia includes a patient-side app for guided remote capture using the front camera, under the same SAPHIR™ framework, for follow-up between visits.
What each adds on top
PhotoDoc adds facial-analysis overlays and collage tooling for presentation and education. evooia adds reproducibility as a named, documented framework plus the integrated clinical record. Different value on top of the same smartphone base.
When is PhotoDoc the better choice?
Practices that need to capture, store, and organise a very large volume of patient photos across iOS, Android, and web, where facial-analysis overlays and collage tooling are useful in consultation, and where consent and clinical notes already live elsewhere.
When is evooia the right choice?
Practices where the bottleneck is reproducibility rather than photo volume. Clinics that want consent and clinical notes attached directly to the image record. Multi-site groups needing identical reproducibility across staff and locations. Clinics building remote patient self-capture programmes between visits.

Frequently asked questions
Can I move existing photos from another tool into evooia?
Yes. evooia supports importing existing before-and-after images from the device or from another tool, and applies SAPHIR™ alignment in post-processing where the source images allow. Switching from a legacy or hardware-based system is straightforward, your historical images come across and new captures are reproducible from the first session.
Is evooia an alternative to PhotoDoc?
Yes. Both are smartphone-native tools with no hardware. PhotoDoc standardises with framing templates and a manual ghost-photo overlay, plus facial analysis and large photo libraries. evooia is built on the SAPHIR™ framework for automatic alignment, with integrated consent and clinical notes and front-camera patient self-capture.
How does PhotoDoc align before-and-after photos?
PhotoDoc uses framing templates and a ghost-photo feature, where a faded version of the prior photo is shown so the user can match it manually before capture. evooia's SAPHIR™ alignment is automatic during capture, with no manual matching step.
Does PhotoDoc include patient consent and clinical notes?
PhotoDoc supports categories and notes attached to photos and secure cloud storage separated from the device gallery, but built-in patient consent and integrated clinical notes are not part of its stated feature set. evooia stores image, consent, and clinical note together in one record.
What is SAPHIR™ by evooia?
SAPHIR™, Swiss Aesthetic Protocol for High-fidelity Imaging Reproducibility, is the reproducible aesthetic imaging framework underlying evooia. It ensures consistent lighting, distance, angle, and framing on every iPhone or iPad capture.
