Every metric. No noise.
NIGHT MODE
Tap. Phone goes hi-vis.
High-contrast inverted display for dawn and dusk runs. Tap once and the active-run screen flips to a high-luminosity lime background with deep-black text — readable at a glance through 5 a.m. fog or 10 p.m. lamplight. Activity-aware: lime for runs, orange for walks. Dark gets bright. Bright gets readable. Free for every Kova user, on every plan, forever. Try it →

GPS + PACE
Pace that breathes.
Navigation-grade GPS — the same precision tier Apple Maps uses for turn-by-turn directions. Pace updates on a 15-second rolling window so it tracks the run, not the GPS jitter. Slow on the hill, the number knows. Pick it back up mid-stride, the number knows. No more lying clock face.
HEART RATE
Drift, zones, no badges.
Live heart rate streamed from your Apple Watch every second. Polarised zone time — how much of the run was easy, how much was threshold, how much was hard. HR drift across the second half tells you when the tempo cooked you. No achievements. No five-zone chart in primary colours.
CADENCE
Steps, counted by Apple.
Cadence reads from Apple's own step counter — the same one Health uses — not a derived estimate. The run average comes from your iPhone's verified step record after the run, not from a noisy live accumulator. Live cadence on the watch face. Run average on the summary. Numbers you can train to.
ELEVATION
Barometer, not GPS guess.
Elevation comes from the iPhone and Apple Watch barometer, not the GPS altitude estimate. A flat track loop reads ≤ 5 metres of phantom gain. A known 50-metre hill reads within 10 percent. GPS altitude only fills in when the barometer can't, with a vertical-accuracy gate. Real climb, real claim.
SPLITS + GOALS
Auto-splits. Set-distance, set-time.
Splits drop automatically at every kilometre or mile — your choice in Settings. Set-distance mode runs to a target — 5K, 10K, half. Set-time mode runs to a clock — 30, 45, 60 minutes. Audio cue every split. The Watch shows the last three. The summary shows them all.
WATCH APP
Three pages, no fluff.
Page 1 — pace, distance, time, heart rate. Page 2 — cadence, splits, goal ring. Page 3 — pause, end. That's the whole interface. Background location keeps the run alive when the screen sleeps. A single complication shows distance today on your watch face. The watch is the run.
TRAINING LOAD
ACWR. HR drift. The ratio.
Acute-to-chronic workload ratio compares the last 7 days to the last 28. The sports-medicine sweet spot is 0.8 to 1.3. KOVA shows the number, the zone, and the trend. HR drift over 14 days flags when easy runs aren't easy any more. Coach yourself with the same numbers a coach would.
PERSONAL BESTS
1K. 5K. 10K. Half.
Every run and walk is checked against four distance records. Beat one and the watch flashes lime, the summary screen says so. The attempts log shows every PB-eligible session — the ones you hit, the ones you missed. Personal Bests are free forever, on every tier. The hook, and we kept it.
