Dermline
Dermline is a private skin diary. Record a flare in seconds and let the app show the pattern in your own entries, then take one clear page to your dermatologist.
Apps for iPhone
Small apps that do one thing well.
mk-sd makes small iPhone apps, each built to do one job. One person builds and supports all of them. Help, manuals and the legal texts for every app live on this site.
01 · The apps
FoodNoteBook
FoodNoteBook logs a meal from a photo or a spoken sentence, and works out the calories and macros.
Gutline
Gutline is a private diary for digestive symptoms. Record an entry in about ten seconds and let the app show the pattern in your own entries, then take one clear page to your doctor.
Kettra
Kettra turns each habit into a visible chain and asks for nothing in return: no account, no sign-up, no data leaving the phone.
Looks Maxxing Studio
Looks Maxxing holds your face up to the golden ratio template and turns it into a game. Everything runs on the iPhone, free, with no account and no ads.
Paletteline
Paletteline is your personal colour analysis. One photo in daylight or seven short questions, and you get one of the twelve seasons, your four dimensions and the palette that goes with them, tried out on your own photo.
Plateline
Plateline logs a strength session in one tap per set, and tells you which plates to put on the bar.
Sixteen
Sixteen paces the runs and logs every station of a hybrid race, so training matches the format the race is actually run in.
