What's tkDerm touch?

tkDerm touch is a dermatological image database client suitable for use by clinical dermatologists.
It runs on Apple's iPad.

As a database client, tkDerm touch needs a server computer to which it connects and setting up the server is up to you. On how to set up the server, please refer to the Documentation section below.

Taking pictures of patients is an essential part of dermatological practice.
Keeping clinical photos in an easily searchable and reusable state is a time-consuming task and
many dermatologists have been looking for a tool to store their photos in such a way as to support clinical practice efficiently.
tkDerm touch was created to fulfill the dermatogists' need.
It is software of the eating-your-own-dog-food type as it was developed by a dermatologist facing such a need every day.

Features of tkDerm touch include:

It maps data to photos automatically based on the timestamps of digital photos.
You can find photos you want rapidly by browsing data in alphabetical order of patients' names or diagnoses or in order by the time of shooting or accessing photos.
You can find photos by the distribution of an eruption as a search key.
It takes you less time to shoot photos for following up a patient by reusing the patient's data you saved at the previous visit.
Enjoying the benefits of the handiness of the iPad, you can recognize a subtle change of an eruption from the previous visit by side_by_side comparison between a present eruption and the photo displayed on the device.
Double-tapping a portion of a photo will enlarge it in such a way that the portion you tapped will be near the center of the enlarged image, which enables you to see details of an eruption easily.
When rotating the device, photos will enlarge or shrink automatically to fit the new orientation of the device.
By pinching, you can change the size of photos being shown as you like.
