Sick Log

Read full description

Sick Log keeps track of when you, your kids, or anyone you care for is sick. When someone's unwell, the last thing you need is a complicated app. Log symptoms, temperatures and medications in a few taps, and get back to looking after them. Later, when the doctor asks "how long has this been going on?" or "how many times have they been sick this year?", the answer is right there. LOG IN A FEW TAPS • Symptoms and notes for each day of an illness • Temperatures and medications, with times and doses • From a single day to an illness that lasts weeks KEEP TRACK OF VISITS • Doctor's appointments, tests and vaccinations • Past or upcoming, whether someone's sick or not SEE THE PATTERN • A calendar with everyone in their own colour • A temperature chart that shows how a fever is going • Every illness in one list, easy to look back on and search A PROFILE FOR EVERYONE • Allergies, medical history and more, all in one place • Handy at the doctor, the pharmacy or daycare YOUR DATA STAYS YOURS • No account to create, no ads, no tracking • Syncs through your own private iCloud • Export your data at any time FREE, WITH AN OPTIONAL UPGRADE Sick Log is free for one person, with every feature included. A one-time purchase of Sick Log Pro unlocks unlimited people — no subscription. Sick Log is a record-keeping tool, not a medical device. It doesn't diagnose or give medical advice. If you're worried about someone's health, talk to a doctor.
