A gentle record-keeping notebook for caring for an aging parent. Caring for an elderly parent often means scattered notes, a bulging medication book, and a stack of hospital receipts. Sobani brings it all into one quiet, dignified place β designed for people in their 40s and 50s who care for a parent. A friendly turtle mascot named Kameji watches over your records, reminding you that you don't have to carry it all alone. KEY FEATURES Hospital Visits Log doctor visits with one tap β clinic, department, symptoms, prescriptions, and the doctor's notes. Attach a photo of the prescription or chart. Schedule the next appointment so it doesn't slip your mind. Visit Prep Checklist Choose from 20 general prompts covering changes, medications, daily life, family sharing, and next steps. Add selected prompts directly to a visit note to reduce forgotten questions. Five prompts are free; Sobani Pro unlocks all 20. Medication Reminders Add medications with multiple daily times. Sobani sends gentle reminders so doses aren't missed. Track end dates for time-limited prescriptions.
