evooia vs Crisalix: Documenting Real Results vs Simulating Potential Outcomes
evooia and Crisalix both work from photos, but one documents what actually happened and the other simulates what could happen. They answer different questions at different points in the patient journey.
TL;DR. evooia is a Swiss application implementing SAPHIR™ for reproducible before-and-after photography on iPhone and iPad, built to document real results over time. Crisalix is a Swiss platform for 3D, 4D, VR, and AR simulation, built to show patients a potential outcome before a procedure, generated from a few standard 2D photos with no scanner. They answer different questions: evooia shows whether a treatment delivered a visible result, Crisalix shows what a result could look like before the patient commits. Pick evooia for reproducible documentation, especially of gradual and non-surgical change. Pick Crisalix for surgical consultations where visualizing the outcome drives the decision.
evooia and Crisalix are both Swiss, both work from ordinary photos, and both avoid expensive imaging hardware. But they sit at opposite ends of the patient journey. evooia documents what actually happened: standardized before-and-after photos that line up across visits. Crisalix simulates what could happen: a 3D, 4D, VR, or AR preview of a potential surgical result, shown during the consultation. The question is not which is better, it is whether you need to document real outcomes or visualize potential ones.
Here is how the two compare at a glance:
| evooia | Crisalix | |
|---|---|---|
| Purpose | Document real results over time | Simulate a potential outcome before a procedure |
| Imaging | Reproducible 2D before-and-after (SAPHIR™) | 3D, 4D, VR, and AR simulation from a few 2D photos |
| Hardware | iPhone and iPad | No scanner required |
| Stage in the journey | After and across treatment | During the consultation |
| Best for | Reproducible documentation, including gradual and non-surgical change | Surgical consults where visualizing the outcome drives the decision |
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 Crisalix?
Crisalix is a Swiss medical-aesthetic imaging company, a spin-off from EPFL and the University of Bern, focused on 3D, 4D, virtual reality, and augmented reality simulation. Its purpose is to answer the question patients ask most before cosmetic surgery: what could I look like afterwards? Crisalix generates an interactive 3D model from a few standard 2D photos using AI, with no 3D scanner or dedicated hardware, and supports simulation for breast augmentation, rhinoplasty, facial procedures, and body contouring. A patient-facing app lets patients view and explore simulations, including remotely. Crisalix is a simulation and consultation tool, not a before-and-after documentation system or a practice management platform. It adheres to GDPR and states that it comports with HIPAA, while noting it is not itself a HIPAA-covered entity.
How are evooia and Crisalix different?
Documentation vs simulation
evooia documents real results: reproducible before-and-after photographs captured under SAPHIR™ so that the same patient, photographed at different visits, lines up directly. Crisalix simulates potential results: a predicted 3D preview shown before treatment. One records what happened, the other previews what might. Crisalix is explicit that a simulation is for visualization and does not guarantee an outcome.
Where each sits in the patient journey
Crisalix lives in the pre-treatment consultation, helping a patient decide by making a potential outcome tangible. evooia lives across the treatment timeline, documenting the actual result session after session. A surgical practice may want both: Crisalix to help the patient visualize and commit, evooia to document the real outcome afterwards.
Surgical visualization vs gradual change
Crisalix is built for procedures where the outcome is dramatic and visual: breast augmentation, rhinoplasty, body contouring. evooia is built for change that is real but often gradual, where reproducibility is what makes the result visible: injectables, lasers, skin and regenerative treatments, and the post-procedure photo trail of any treatment.
Output
Crisalix produces an interactive 3D, 4D, VR, or AR model of a potential look. evooia produces reproducible 2D photographs that are directly comparable over time. Both start from ordinary photos and neither needs a scanner, what differs is whether the output is a simulation or a documented record.
Patient self-capture and remote use
Both have a patient-facing layer. Crisalix lets patients view and explore simulations remotely. evooia lets patients capture their own reproducible progress photos between visits using the front camera, under the same SAPHIR™ framework. The remote use case is different: viewing a simulation versus capturing standardized documentation.
Compliance
evooia is hosted in Switzerland, built for GDPR and Swiss FADP compliance, and designed to support HIPAA-compliant deployments. Crisalix adheres to GDPR and states that it comports with HIPAA while noting it is not a HIPAA-covered entity. For clinics assessing data protection during procurement, confirm hosting, retention, consent, and processing terms with each vendor directly.
When is Crisalix the better choice?
Plastic surgery and cosmetic practices where the consultation depends on the patient visualizing a potential outcome: breast augmentation, rhinoplasty, facial surgery, body contouring. Clinics where 3D, VR, or AR simulation is itself a conversion driver, helping patients move from abstract discussion to a concrete preview before committing.
When is evooia the right choice?
Practices whose need is documenting real, comparable outcomes over time rather than simulating them. Dermatology, lasers, injectables, regenerative aesthetics, and the post-procedure documentation of any treatment, where results are real but subtle or gradual. Multi-site clinics needing consistent reproducibility across staff and locations. Practices running remote follow-up photo programmes between visits.
Some surgical practices run both: Crisalix for the pre-operative consultation where the patient visualizes the outcome, evooia for the reproducible documentation of the result that follows.

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 Crisalix?
Not directly. evooia documents real, reproducible before-and-after results over time. Crisalix simulates a potential outcome before a procedure in 3D, 4D, VR, and AR. A practice may use Crisalix for the consultation and evooia for the documentation.
Does Crisalix need a 3D scanner?
No. Crisalix builds its 3D models from a few standard 2D photos using AI, with no scanner or special hardware. evooia also needs no hardware, it captures reproducible 2D photos on iPhone or iPad.
Does Crisalix document actual treatment results over time?
Crisalix is built to visualize potential outcomes before treatment, not to track standardized real results across visits. For reproducible longitudinal before-and-after documentation, evooia is purpose-built.
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 capture.
