Independent evidence on connected diagnostic devices
What a connected device image can show, and where it stops
Careful reading on home imaging tools, optics, image quality, privacy and the limits of health images.
Four ways into the evidence
Ear images and small-scale optics
Read how smartphone otoscopy and mobile microscopy are studied, from image quality and remote review to reference standards and rater agreement.
How to read a diagnostic study
Learn how studies are built and reported, including bias, blinding, missing data, thresholds, unreadable results and predictive values.
How devices are classified and watched
See what intended use, FDA databases, recalls, software changes and postmarket monitoring mean, and how to read a performance claim.
Using connected tools in practice
Follow the practical side: interoperability, image storage, privacy, usability, training, error handling and how an image fits its context.
Home imaging, optics and image limits
The subject is consumer health imaging. That includes microscopy and optics literacy, image quality, device limitations and privacy. It also covers safe next steps for people comparing home imaging tools, caregivers, students, and readers trying to understand a health image.
What stays outside this notebook
We do not publish diagnosis from images. We do not offer device repair or support for former products. We do not interpret images remotely. We do not provide clinical services, store patient data, or endorse sellers.
Checks you can make on every guide
Open any substantive guide and you can check four things. It names its sources. It separates guidance from uncertain evidence. It shows a review date. It gives a route to send a correction. Some things are left out on purpose. The foundation pages carry no affiliate links, no rankings, no vendor calls to action and no paid referrals.
