New: • “Your calculation today”: start, planned and use in one line with a bar • New page “How every number comes about”: explains everything with your own values • Load redefined: shows how much of your morning value is used today (82 % = 82), the aftermath of the last days is shown separately • Below 5 % Reserve shows the hint “Take it easy” instead of a number • Standalone Apple Watch app: reads sleep, HRV and heart rate from Health itself, calculates reserve and load itself and takes check-ins and activities directly – even without your iPhone nearby • Live activity on the watch: timer, heart rate and energy run along, measured kcal are compared with the expectation, costs adapt to you, and a calm hint to rest appears if use is clearly higher • During setup Reserve asks for your energy capacity • The tutorial now explains your load profile and where to set it Fixes: • “Reset all data” now really deletes everything you entered – including medications, name and profile • Version is shown in Settings • Consistent time periods and thresholds in all explanations • Siri answers “Take it easy” instead of a number below 5 % • Corrected notes on privacy, Health access and iCloud backup
Reserve helps you track and intentionally manage your energy with ME/CFS and Long COVID (pacing) — at your own pace. Reserve is a journaling and self-management tool. It does not provide diagnoses and is not a medical device — it helps you keep track of your energy, symptoms, and good and bad days. YOUR ENERGY RESERVE A quick morning check-in on sleep, energy, and brain fog — combined with your Apple Health data (sleep including deep and REM stages, heart rate variability, resting heart rate) — gives you a personal "Energy Reserve." It's based on your own 14-day average and decreases throughout the day with your exertion. APPLE WATCH See your Reserve right on your wrist and start activities without reaching for your iPhone. A watch face complication shows your current level at a glance. SIRI SHORTCUTS Ask for your current Reserve, start your morning check-in, or open the activity planner — by voice through Siri or the Shortcuts app, without opening the app. PLAN ACTIVITIES In the Simulator, estimate how much an activity might cost — physically, orthostatically, cognitively, and emotionally. This helps you make deliberate decisions and spread exertion throughout the day. DIARY & MEDICATIONS Log symptoms, crashes, and notes — even retroactively with any date. Enter your medications and supplements with individual dosage and time, including reminders for each dose; they appear daily until you remove them. TRENDS See the history of Body Battery, HRV, resting heart rate, sleep, and active energy — with a freely selectable time range (3 days to 6 months), average line, and day-of-week pattern comparison. REPORT FOR YOUR DOCTOR Export your data as a clear PDF — with trend graphs, daily values, check-ins, diary entries, and medications. Handy for referring to concrete records during appointments. PRIVATE Your data stays on your device — no server of our own, no tracking, no account with us. You can optionally enable backup through your private iCloud account so your diary, medications, and history carry over when you switch devices; this runs entirely through Apple's iCloud, not through us. Apple Health data is used read-only. Reserve does not replace medical advice. Please make medical decisions together with your care team.
