ImaJine Swim: Swim Tracker

A swim tracker for Wear OS 3+ built for people who count laps, chase a faster 100 and want to see which lap was the efficient one – without a phone, an account or a subscription.

WHY SWIMMERS PICK IT
• Per-lap SWOLF (seconds + strokes) with your best lap highlighted, so you see efficiency, not just distance
• Stroke tags: pick freestyle, backstroke, breaststroke or butterfly before a set and switch mid-swim – the summary shows your stroke mix
• Lane-rope ring around the bezel counts laps in the current set of 20, readable through goggles at a glance
• One physical button does everything underwater: tap = mark a lap, double-press = pause menu / unlock
• Water lock turns on the moment you start; a 3 s screen hold unlocks on watches without a free button
• Water eject: an 8-second low-frequency tone clears the speaker after you unlock

WHAT IT TRACKS
• Pool: 25 m, 50 m or a custom length, meters or yards. Laps and distance come from your watch's swim detection (Health Services); a manual-lap fallback works on any watch
• Open water: GPS distance, route and straight-line distance
• Time, pace per 100 m/yd, strokes per lap, calories
• Heart rate with 5 zones based on your max heart rate, plus time in each zone
• Always-on ambient view while swimming: time and distance only, easy on the battery

AFTER THE SWIM
Three summary pages on the watch: totals, stroke mix + SWOLF by lap, heart-rate zones. Every session is kept in the watch's history.

PRIVACY
All data stays on your watch. No account, no cloud, no ads, no analytics. Heart rate and location are used only while a swim is running.

COMPATIBILITY
Wear OS 3 or newer (Galaxy Watch4 and later, Pixel Watch, OnePlus Watch and others). Automatic lap and stroke counting depends on the watch's swim sensors; watches without them get a timer with manual laps and heart rate.
