Perim brings symptom tracking, mood check-ins, nutrition, movement, and private support together in one calm app made for perimenopause. Use it for a few seconds each day or explore your history in more detail when you want to understand what has been changing. QUICK DAILY CHECK-INS Log hot flashes, night sweats, sleep, mood, energy, bleeding, and other symptoms without turning your day into a project. Add a note when something matters, skip anything that does not, and come back whenever it feels useful. SEE PATTERNS OVER TIME Turn your check-ins into clear weekly and monthly views. Compare symptoms, sleep, mood, and cycle changes so you can notice patterns and remember what helped. CALORIE & NUTRITION TRACKER Keep a simple meal log with calories, protein, carbohydrates, and fat. Review your day without judgment, edit any entry, and use practical nutrition guidance designed around the needs of perimenopause. SCAN A MEAL PHOTO Take a photo of your meal to get an estimated food list, calories, and macros. Check and edit the estimate before saving it, because photo-based nutrition estimates are helpful guidesβnot exact measurements. WORKOUTS FOR CHANGING ENERGY Choose guided strength, mobility, pelvic floor, cardio, and recovery sessions that fit your time and energy. Follow each exercise on screen, pause when you need to, and build a movement routine at your own pace. MOOD & SYMPTOM SUPPORT Regular mood check-ins help you see how emotional changes may connect with sleep, symptoms, food, and daily life. Perim keeps the experience gentle: no shame, no streak pressure, and no punishment for missed days. ASK PERIM Ask questions about perimenopause, symptoms, sleep, mood, nutrition, or movement in simple language. The assistant can use a short summary of the information you have logged to give a more relevant answer. It is designed for education and support, not diagnosis or emergency care. REPORTS FOR DOCTOR APPOINTMENTS Create a clear 30-, 60-, or 90-day PDF summary of the symptoms and changes you recorded. Share it only when you choose, so you can spend less time trying to remember details and more time having a useful conversation with your clinician. PRIVACY, EXPLAINED CLEARLY Your core health journal stays on your device. Check-ins, saved meal entries, workout history, and generated doctor reports are stored locally. We do not sell your personal health information or use the content you enter for advertising. Optional online features send only what is needed to provide the feature: β’ Meal Scan sends the photo you choose to the analysis service and returns an estimate for you to review. β’ Ask Perim encrypts your message and its short supporting context on your device before sending them. The request can be opened at Perim's assistant service only with the corresponding private key. This means internet providers and other network intermediaries cannot read the message content while it is in transit. β’ Assistant requests use an anonymous app account rather than your name or email address. Your saved journal remains under your control, and sharing a doctor report is always your choice. ACCESS & PURCHASES Some features and content require Perim Pro, available through an auto-renewing subscription or a one-time in-app purchase. Options and prices are shown before purchase. Subscriptions can be managed or canceled in your Apple ID settings. IMPORTANT Perim is a personal tracking and wellness app. It is not a medical device and does not provide medical advice, diagnosis, treatment, or emergency monitoring. Nutrition and calorie estimates may be inaccurate. If a symptom worries you, contact a qualified healthcare professional.

Verdict
The clearest difference is iOS requirement: Heft at 15.1 against Perim's 17.6. On price, ads, in-app purchases and device support there is nothing between them.
