About

Reserve helps you track and mindfully manage your energy with ME/CFS and Long COVID (pacing) – at your own pace. Reserve is a journaling and self-organization tool. It does not provide diagnoses and is not a medical device – it helps you keep an overview of your energy, symptoms and good and bad days. YOUR ENERGY RESERVE A short morning check-in on sleep, energy and brain fog – together with your Apple Health data (sleep incl. deep and REM stages, heart rate variability, resting heart rate), Reserve shows a personal "energy reserve". It's based on your own 14-day average and declines over the day with your exertion. PLAN ACTIVITIES In the simulator you estimate how much an activity might cost – physically, upright (orthostatic), cognitively and emotionally. That helps you decide mindfully and spread exertion across the day. DIARY & MEDICATIONS Record symptoms, crashes and notes. Add your medications and supplements with dosage and time of day – they appear daily until you delete them. TRENDS See the history of body battery, HRV, resting HR, sleep and active energy – with a selectable time range (3 days to 6 months) and an average line. REPORT FOR YOUR DOCTOR Export your data as a clear PDF – with trend charts, daily values, check-in, diary and medications. Handy for referring to concrete records during appointments. PRIVATE Everything stays on your device. No account, no server, no tracking. Apple Health data is used read-only. Reserve is no substitute for medical advice. Please make medical decisions together with your care team.
