About

ChangeDay

Features
Read full description

ChangeDay helps people with Type 1 Diabetes and their caregivers remember when insulin infusion sites, CGMs, and pump batteries were last changed, and when they are due next. Built for simple shared routines, ChangeDay keeps the focus on the three things you need to check quickly: your site, your sensor, and your pump battery. Log a change in one tap, see the next due day, and optionally share the same tracker with a caregiver or family member using Apple’s CloudKit Sharing. Whether you are tracking your own routine or helping someone else stay organized, ChangeDay is designed to be calm, private, and easy to use. Key features: β€’ Track insulin infusion site changes β€’ Track glucose sensor change days β€’ Track insulin pump battery changes β€’ See last changed and next due dates at a glance β€’ Log site, sensor, or pump battery changes in one tap β€’ View upcoming change days on a simple calendar β€’ Review change history β€’ Set local reminders for due dates β€’ Share one tracker with another person using iCloud/CloudKit Sharing β€’ Keep data stored locally and in your personal iCloud account β€’ No account, ads, or subscription ChangeDay is intentionally simple. It is not a blood glucose tracker, dosing calculator, medication manager, or diabetes treatment app. It does not provide medical advice, dosing guidance, diagnosis, treatment recommendations, or emergency alerts. Always follow guidance from your clinician and the instructions from your device manufacturer.
