FrontRunner's weekly pack on a phone: your row climbs from fourth to second, across the dashed line where the top fifth go up.
FrontRunner's weekly ladder: eight tiers from Rookie to Legend, your pack in Regional, one place below the line where the top fifth go up on Monday.

FrontRunner

SS 171 556

Running challenges where effort beats mileage: every run is scored against your own usual pace, so anyone can win. Weekly ranked leagues move the top of each pack up a division, rivals settle it in head-to-head duels, and groups pool their kilometres to run famous routes like the South West Coast Path.

Stargazer's briefing on a Garmin watch: Eta Aquariids active; ISS 17:41 from the south, decent; sunset 19:38, dark 22:22, sunrise 04:12; Jupiter and Venus up; waning crescent moon 8 per cent, rising 02:40, setting 16:55.

Stargazer

SS 181 516

Tonight’s sky on your wrist: which planets are up, the moon, when it gets properly dark and when the ISS passes over. The ISS passes are worked out on the watch itself, with a port of SGP4, the standard satellite model.

PacePulse

SS 181 376

A metronome for runs, rows and rides that stays quiet while you hold your cadence, and buzzes only when you drift out of your band.

The adaptive bands at the default 175 target, ±5, drawn from the app’s own thresholds. Below 165 is too slow, 165 to 169 speed up, 170 to 180 locked in, 181 to 185 slow down, above 185 too fast.
