When you're managing someone's care at home, the details get scattered across notebooks, text messages, and memory. It's hard to stay organized and even harder to keep others in the loop. Carespondence™ gives family and home caregivers one simple place to document care, stay organized, and keep everyone informed. LOG CARE AS IT HAPPENS Tap through simple, pre-built selection menus to record care tasks, medications, vital signs, and observations in seconds. Set reminders for recurring care tasks so nothing gets missed. No typing required, no figuring out what to log. Carespondence meets you in the moment so nothing gets forgotten. YOUR CARE HISTORY, ALWAYS ORGANIZED AND READY Every entry is automatically organized into a clear, continuous timeline. No relying on memory. No piecing things together later. Everything is captured and organized as it happens. KEEP EVERYONE IN THE LOOP Invite family members or fellow caregivers to log care for the same person, so everyone contributing to care is working from one shared record. Generate a clear care report and share it with family members or care teams in just a few taps. Everyone stays in the loop without extra calls or messages. WHO CARESPONDENCE IS FOR Carespondence is for everyone who has stepped up to care for someone, whether you're a family member caring for a loved one or a professional caregiver supporting a client. If you want to feel more organized, more confident, and better aligned with the people who need to stay informed about care, this was made for you. Try Carespondence free for 7 days. After your trial, continue with a monthly plan ($9.99/month) or save 50% with an annual plan ($59.99/year). Cancel anytime before your trial ends and you won't be charged.
