POLARITY is a daily tracker for people living with bipolar I or II. Record mood, sleep, energy and medication to see changes over time and bring your recorded history into conversations with a clinician. ONE DAILY CHECK-IN Take a few minutes to record your day: mood, depressive thoughts, energy, motivation, anxiety, irritability, sleep, food and water. Add medication, everyday factors and notes to keep the context. Missing a day does not erase your history. Continue when you feel ready. NOTICE WHAT REPEATS Look back at changes in mood, sleep and other measures. Your entries help you recall what accompanied the highs and lows: poor sleep, stress, social activity or changes in your routine. Changes happening together do not establish a cause. REFLECTIONS BASED ON YOUR ENTRIES POLARITY brings observations from your entries into a short reflection: what changed in mood, sleep and energy, and what kept recurring. Daily reflections are available after three days with check-ins. Reflections for a selected period help you look at several weeks together. REPORTS FOR YOUR APPOINTMENT Before a visit, bring your mood, sleep and medication history together in a PDF. Discuss important changes with your clinician without relying only on memory. Choose 7, 14, 30, 60 or 90 days, or a custom period of up to one year. You decide who to share it with. APPLE HEALTH With your permission, POLARITY shows sleep, activity and other data from Apple Health. Access is read-only, and the app also works without it. MEDICATION AND REMINDERS Log your prescribed medication and check what you have recorded for the day. Turn on medication and check-in reminders if you need them. PRIVATE STORAGE Entries are stored on your device. You can sync the data you enter with your private iCloud database; the developer cannot access it. Apple Health data, reflection text and PDF files do not sync to iCloud. Reflections are created on your device without sending your entries to external AI services. You can lock the app with Face ID and export a backup. MOONDUST AND POLARITY PREMIUM Earn Moondust through check-ins and medication logs, then use it to create reflections and reports. Moondust cannot be bought with money. Premium unlocks all analysis periods, reflections for a selected period and full reports. Creating reflections and reports still requires Moondust. Premium offers a monthly or yearly subscription. The price is shown in your local currency before purchase. Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your App Store settings. POLARITY is a self-tracking tool. It does not provide medical advice, diagnosis or treatment and does not replace professional medical care.

Obsessed

Obsessed is not a wellness app. It does not celebrate you for showing up. It takes the goal you claim, turns it into a standard, and checks every day whether your actions matched it. YOU BRING YOUR OWN TRAINING Type in the split you already run, import it from Strong, Hevy or FitNotes, paste a written program, or copy a friend's with an eight-character code. If you would rather we wrote one, we will. Either way it becomes the standard you are held to - and it learns: finish a session we never prescribed and that weekday becomes part of your week. PROGRESSIVE OVERLOAD, DECIDED BY THE WORK Top your rep range on every set and the weight goes up. Come up short and it holds. Leave early and it holds too - no easier target for doing less. Drop sets, back-offs, warm-ups and sets to failure are each judged on their own terms. FOOD, CHECKED AGAINST THE GOAL YOU CLAIMED Type what you ate in your own words, or enter the barcode and get the numbers off the box. We do not recommend a diet. We check whether what you logged aligns with the goal you set - calories and protein, two-sided and asymmetric, with the tolerance your goal actually implies. A GRADE EVERY DAY, AND A RECEIPT EVERY WEEK Training and nutrition fold into one letter, S to F. Monday morning brings a receipt: sessions trained, aligned days, what moved on the bar, what it cost you. CONSEQUENCES THAT MEAN SOMETHING Three bad days and you are on The Bench for seven - locked out, history kept. Injury, sickness and emergencies are answered honestly, and you get one waiver a month. Travel is declared in advance, not used as an excuse afterwards. Two clean weeks at an A clears a strike. THREE VOICES Locked In is direct. Obsessed is sharper. Possessed does not let anything go. The voice changes; the standard never does. Obsessed attacks the behaviour, never the person. Obsessed is $14.99/month or $89.99/year, starting with a 14-day free trial. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.

Verdict
The clearest difference is in-app purchases: Obsessed at none against POLARITY's 2. Obsessed also leads on iOS requirement (15.1 vs 18.0). On price, update cadence, ads and device support there is nothing between them.
