Volta is a science-backed menopause companion for women in perimenopause, menopause, and post-menopause. It puts symptoms, food, workouts, and weight in one place, so you can see what's actually happening. Generic trackers miss the menopause context. Sleep may feel lighter, recovery may take longer, hot flashes or night sweats may disrupt routines, cravings may shift, and muscle matters more than it used to. Volta connects those dots and suggests a practical next step, not just another number to log. And when you finally get that doctor's appointment, you'll have a real log of what you've been dealing with. Volta can generate a shareable summary from your data to bring with you. With Volta, you can: - Track calories, protein, meals, and menopause nutrition patterns. - Follow workout guidance built around strength, recovery, and readiness. - Build muscle with protein-first nutrition and resistance training support. - Log symptoms, sleep, mood, energy, hot flashes, and night sweats. - Connect weight, workouts, food, recovery, and menopause symptoms over time. - Use daily guidance to know when to push, lift, recover, or refuel. - Review weekly trends for calories, protein, workouts, sleep, and body composition. Volta is not a diagnosis tool, medical device, treatment plan, or guarantee of weight loss. It is a menopause-focused tracking and guidance app for women working on nutrition, strength, recovery, and body composition. Volta is free to download. Access to Volta Pro features, including personalized guidance, advanced tracking, trend insights, and protocols requires a separate auto-renewing subscription purchased in the app. Plan options and local pricing are shown before purchase, and subscriptions can be managed or canceled in App Store settings.

Lun

Lun is a migraine diary built around one simple truth: you cannot fill in a form while a migraine is happening. So one long press is all it takes to log an attack. The details can always wait until you are ready. Over time, Lun gathers your log into patterns you can actually use: when attacks come, how strong they are, what keeps recurring, and how sleep, cycle and air pressure play in. HOW YOU USE IT Hold the breathing circle on the home screen when an attack begins. The time is saved at once. Add intensity, symptoms and triggers once you are back on your feet, or leave it. WHAT YOU GET Log attacks with one press, unlimited. History and a calm calendar. Core patterns and triggers. When in the week and the day attacks come, and how strong. Reminders and an overview of your medicines. WITH LUN+ How air pressure, sleep and cycle connect to your attacks. A heads up if you near the point where acute medication, taken too often, can itself cause headaches. A tidy report you can bring to your doctor. PRIVACY IS THE WHOLE POINT Everything you log stays on your device, and syncs only through your own private iCloud. No server, no ads, no tracking. The only thing that leaves your device is a coarse, rounded location when you want to see air pressure, and it never contains health data. Lun does not diagnose. It shows patterns and points you to a doctor when needed. Lun is the first health app from Haug & Datter. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
