why people still pay for Memtime
People still pay for Memtime because the timer is simple, but people pay for frictionless capture and a history they trust enough to invoice or change habits from. The recurring cost buys idle detection, permissions, app metadata, privacy, notifications, sync, reports, integrations, and backups, not just the visible interface. If none of that applies to you, any pick above saves $168 a year.
