Apsia - Adaptive Running Coach
Train with the tide, not against it.
Most running apps hand you a static plan and expect your body to follow it. But readiness moves every day. Sleep, stress and recovery all shift - and runners end up pushing hard on a morning their body had nothing to give. Apsia reads your recovery signals: HRV, resting heart rate, sleep and answers one question each morning: push, or recover?
The name comes from apsis, the turning point of an orbit. The far point is the apoapsis, the near one the periapsis. Your readiness is a position on that orbit: at apoapsis you're primed and the plan favours a hard effort; near periapsis it pulls back and protects recovery. It's also the visual signature, instead of another progress ring, the home screen shows your state as a single glowing node on an ellipse. Apsia doesn't hand down orders. The node's position is the readout, no raw score to decode. High on the arc, a hard session is on the table. Low, it offers to swap today's intervals for an easy run, and tells you why. The plan bends to your body, but the call stays yours. A coach that suggests, not a plan that commands.
Colour only carries state. Two signals on a near-black canvas. Mint (#4DF5B0) means ready or on pace. Rosé means strain or recovery. Nothing is coloured for decoration. On a low readiness day, the whole product shifts tone. Big numbers, readable mid-stride. Space Grotesk for the large data (readiness score, pace, time), a mono for labels. The type is made for glancing, not reading. The watch comes first during a run. Nobody reads their phone mid-effort. The watch face keeps only the orbit, pace and heart rate. Every state has to read in under a second.
