Tandem is a self-hosted co-parenting app: a shared parenting-time calendar with swap requests both parents must accept, permanent tamper-evident messages with read receipts, shared expenses with automatic splits, school and district calendar subscriptions (iCal/RSS) with days off flagged, a child profile with insurance cards and care team, a document library for the parenting plan and records, optional voice calls between parents with recording when both agree, an exchange log, a private journal, and printable court-ready reports. Installs on iPhone and Android from the browser like a native app. All data lives in /data (one SQLite file plus uploaded files).

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.
