An iPhone practice tracker that measures playing time, rest, streaks, focus areas, and practice history, with optional Strava sharing.

Landing page captured for the 2026-08-20 issue.

Why it surfaced

Duende treats practice like athletic training: its wall-clock timer keeps counting when the phone is locked, while an optional on-device microphone distinguishes playing from silence without uploading audio. The copy has a clear thesis too—“The unglamorous Tuesdays add up to something visible.”
