Chumlord

Chumlord tracks how often you stay in touch with friends and family. Add people to a roster (manually or from your contacts), set a catchup cadence per person (daily, weekly, monthly, custom, etc.), and log catchups when they happen. The main list splits into Scheduled and Coming Due. Coming Due is ranked by who merits attention most relative to their own cadence, so you can quickly triage who to reach out to first. Each row shows the friend's avatar, cadence, next or last catchup date, and a health percentage from 0 to 100. Tap a row to edit, tap the calendar icon to schedule a date, swipe to text or snooze. I created Chumlord as a passion project. No account, no server, no analytics. Everything stays on your device. Chumlord doesn't send notifications; you open it when you want to see where things stand.
