Pacing for ME/CFS & Long Covid
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
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.

Version 1.2 is here – the first major update for Reserve!
Since launch, we've been collecting your feedback – and today we deliver! This update brings several long-awaited features and important bug fixes. Thank you to everyone who wrote to us. You make Reserve better.
New Features
• Language selection at first launch: Reserve now asks you right when you first open it whether you prefer German or English. Can be changed at any time in Settings.
• 23 new activities: Hair washing, Getting dressed, Dishes, Laundry, Stairs, Cycling, Driving, Shopping, Paperwork, Research, Reading, Phone calls, Desk work, Meetings, Drawing/Painting, Listening to music, TV/Series, Doctor's visit, Physiotherapy, Stretching, Breathing exercise, Nap ... and more!
• Create custom activities: Missing an activity? Create it yourself! Answer four short questions about exertion, being upright, cognition, and emotions – Reserve calculates the rest just like the built-in activities. Long-press to delete.
• Home Screen & Lock Screen Widgets: Reserve is now visible directly on your Home Screen – as a small or medium widget showing your current reserve value and risk indicator. Plus three Lock Screen variants: circular, rectangular, and inline.
• Categories in activity selection: Activities are now sorted by area – Self-care, Movement, Cognitive, Leisure, and Health. A dedicated tab gives quick access to your custom activities and lets you create new ones directly.
Bug Fixes
