This update improves background HRV notifications. • Fixed an issue where a low-HRV notification could be delayed until PaceME was opened. • Improved processing of new HRV readings from Apple Health. • Reduced the risk of duplicate notifications. • Improved diagnostics and overall reliability. Thank you to everyone who tests PaceME and shares feedback!

What’s new in version 2.52: – Improved background updates of health data from Apple Health. – Fixed an issue that could delay HRV notifications until PaceME was opened. – More reliable updates of new or delayed sleep data. – Improved stability when syncing health data.

What’s New in Version 2.50 • Fixed an issue where sleep could be omitted when a sleep period crossed the day boundary. • Improved support for split and fragmented sleep. • More consistent sleep values across iPhone and Apple Watch. • Additional stability improvements and bug fixes.

Improved sleep display from Apple Health: • Evening sleep and split sleep periods are now assigned to the correct sleep day. • Totals are improved when multiple apps or devices record sleep. • Clearer health-data access text and minor fixes. Past sleep values may change because sleep is now assigned to the correct day. Nothing has been deleted.

This version is about sleep. Sleep is now counted as in Apple Health PaceME reads sleep from Apple Health, and now uses the same day division: a sleep day runs from 18:00 to 18:00, not from midnight. Sleep ending in the evening therefore counts toward the next day, just as it does in Health. Previously, evening sleep could drop out of the day's total, and the app could show several hours less than Apple Health. Split sleep is shown as a whole If you slept in separate periods, the Today card now shows the total and how it adds up, for example 2 periods · 1h 57m + 3h 52m. Under Health → Sleep you can see each period with times, and which sleep day is shown. More accurate assessment of split sleep The recommendation is now based on total sleep, not only the longest period. If you sleep in separate periods, for example three and four hours, the day is no longer assessed as critically short sleep. Short sleep still leads to cautious advice. Note After updating, past sleep values may have changed and your average may look different. Old sleep has been moved to the correct day. Nothing has been deleted.

What’s new in version 2.48: • Improved sleep handling when multiple apps or devices save data to Apple Health. Main sleep and additional sleep are shown more clearly, while overlapping records are not counted twice. • Separate HRV and sleep explanations provide more nuanced context for unusual values. • Smoother trend charts and clearer use of status colours. • Improved HRV display and a colour-coded Weather Load complication on Apple Watch. • Better syncing and health-data freshness checks. • Additional accessibility, stability, and interface improvements.

PaceME 2.47 is a major update. Much of the app has been redesigned. Navigation is calmer and information is easier to find. Some screens may feel unfamiliar at first. There is no need to explore everything at once. WHAT IS NEW • A new Health area brings key information together. Capacity, symptoms, HRV, resting heart rate, sleep and steps now have dedicated pages. • Journal can now record symptoms and everyday events. Entries can include notes and perceived energy cost. • Calm Space now includes several breathing modes. Guided audio and a sleep timer are also available. • The Apple Watch app has been redesigned. Daily capacity, Live Pacing and complications are more reliable. • Live Pacing includes clearer safeguards for forgotten sessions. • Weather Load has a clearer presentation. Background updates and Watch delivery are more reliable. • Sleep handling is more accurate across multiple data sources. Long sleep is not treated as proof of recovery. • The readiness check gives clearer weight to PEM. • Health exports and PDF reports contain more useful context. Reports can include symptoms and Journal events. • Health Data Check can explain missing health information. It now includes Apple Watch and Bluetooth diagnostics. • Dates, numbers and health labels are clearer. Norwegian and English formatting have also been improved. ALSO IMPROVED This update includes many smaller fixes. HealthKit refresh and device sync are more reliable. Weather updates and notifications have been strengthened. PDF reports have clearer layouts and improved readability. Accessibility and long-text presentation have also been refined. Thank you for using PaceME. Take your time getting familiar with the new structure.

New in this version: • Apple Watch support with live pacing sessions • Better tracking of capacity throughout the day • Optimized Health → AI export for personal analysis • Improved PDF health report that can be shared with a doctor or clinician • More precise weather sensitivity with barometric pressure and temperature • Improved HRV interpretation based on personal baseline • Better support for mobility and everyday activities • General improvements to stability, language and usability

Version 1.5 is a major update introducing four new features alongside significant improvements to existing ones. WEATHER SENSITIVITY TAB A new tab (swipe left from Today) monitors barometric pressure and temperature in real-time using WeatherKit and the iPhone's built-in barometer. A 3-hour pressure drop rate gives a green, yellow or red PEM risk rating. A 7-day calendar grid shows upcoming risk days at a glance, and a 24-hour sparkline tracks pressure and temperature trends. The 3-day forecast now adjusts capacity recommendations based on weather risk. BREATHING SPACE A full-screen breathing exercise based on the physiological sigh (Balban et al., 2023). Double inhale, hold, long exhale — shown to activate the vagus nerve and support autonomic recovery. The app invites you to open Breathing Space when HRV is low, but it can also be opened manually at any time. HEALTH → AI Export a full year of Apple Health data as a structured CSV file, ready for analysis in ChatGPT or Claude. Includes HRV, resting heart rate, sleep staging, steps, oxygen saturation, respiratory rate, wrist temperature, AFib classification, gait metrics and more — alongside your daily capacity ratings from PaceME. Optional README and nine evidence-based analysis prompts can be included in the export. NOTIFICATIONS Automatic alerts when HRV is low (capped at one per day) and when a significant pressure drop is forecast overnight (capped at one per day). Notification thresholds follow your sensitivity settings. READINESS CHECK IMPROVEMENTS The Readiness Check now opens as a full-screen view with HRV and sleep barriers pre-filled from HealthKit. Layout and sizing have been improved for easier use on difficult days. SETTINGS Weather sensitivity thresholds (pressure and temperature) are now user-adjustable. Celsius and Fahrenheit supported. An info popup explains the clinical relevance of each threshold for ME/CFS and related conditions. Weather sensitivity can now be disabled entirely for users who are not weather sensitive. ICLOUD SYNC Daily logs, weather snapshots and breathing session records now sync automatically across devices via iCloud.

Improved protection logic: one critical red signal now triggers a minimum capacity recommendation. The subjective slider has a hard floor at low values. Forecast view improved with clearer text and layout. About PaceME restructured into five sections with slower read-aloud speed. Something is hidden in the app. Good luck finding it.
