Cognitive behavioural therapy (CBT) is a type of psychotherapy that helps individuals identify and change unhelpful or unhealthy thought patterns and behaviours. The goal of CBT is to positively influence a person’s emotions, behaviour and overall wellbeing. CBT can be used to treat a variety of issues, such as depression, anxiety, phobias and post-traumatic stress disorder. It helps people develop beneficial coping strategies and improve their problem-solving skills. A CBT diary is a tool that is used to record events, thoughts, emotions, body reactions, behaviours, rational responses and cognitive distortions. It is used to track progress over time and help individuals learn more about their thought and behaviour patterns. The diary can also be used to set goals and develop strategies for improving mental health. By writing down their thoughts, emotions, and behaviours, individuals can gain greater insight into their own behaviour and gain new perspectives on the challenges they are facing.

Seborrheic

Managing seborrheic dermatitis means juggling three or four shampoos, timing how long to leave each one on, and checking every new product for hidden triggers. This app keeps track of it for you. SebDerm Tracker lays out your antifungal rotation across the week, reads product ingredient lists for Malassezia triggers, and shows how your own logs and photos change over time. ROTATION SCHEDULER See which product is scheduled today and how long to leave it on, with a countdown timer that keeps running if you put your phone down. Your wash frequency follows your hair type. When the intensive phase ends, the app prompts you to step down to maintenance. STEROID DAY COUNTER If you log a topical steroid on facial skin, the app counts the distinct days and shows you the running total against a conservative caution point — something concrete to raise at your next appointment. PRODUCT SCANNER Photograph an ingredient list and see which ingredients are known to feed Malassezia, and why: fatty acids, their esters, plant oils, polysorbates, fermented ingredients. Tap any flagged ingredient for the mechanism behind it. Ingredients the ruleset does not recognise are shown as unknown, never as safe. DAILY LOG AND FLARES Log itch, redness, flaking and oiliness in about ten seconds. Mark a flare and tag what preceded it. A flare never breaks your streak. PROGRESS A weekly 0-100 self-monitoring score with every component shown, so the number can be argued with. Side-by-side photos with a camera guide that fades your previous shot over the viewfinder, so week-to-week shots line up. FOR YOUR APPOINTMENT Export a PDF of your score trend, treatments, flare history and steroid days. WHAT IS FREE, PERMANENTLY The rotation schedule, the leave-on timer, daily logging, flare tracking, the steroid day counter and every safety prompt are free and always will be.

Verdict
The clearest difference is iOS requirement: Diary at 15.0 against Seborrheic's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Diary sells 1 in-app purchase, starting at $0.99 per month and Seborrheic sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
