Ismooth Run

What Ismooth Run does

iSmoothRun is a privately held Swiss iOS fitness-tracking application operated by Lake Horizon Ltd., founded in 2011. The company serves endurance athletes — primarily runners, with secondary segments in cyclists and triathletes — by providing a single iPhone app and Apple Watch companion that integrates GPS, pedometer, heart rate, cadence, and power-meter sensor data across BT Smart and ANT+ devices (via Wahoo and 4iiii Viiiiva bridges), and exports workouts to 14+ fitness platforms including Strava, Garmin Connect, TrainingPeaks, RunKeeper, Nike+, and others. Its core technical differentiators are the breadth of sensor interoperability, a configurable workout editor with ghost-pace and HR-zone coaching, standalone Apple Watch recording capability, and HealthKit integration.

The product is built natively for Apple's iOS/watchOS ecosystem and does not offer an Android version. Monetization combines a one-time $5.99 'Pro' app purchase with an Annual/Monthly Pro Subscription introduced in v6.2.0 (January 2021) that gates features such as TrainingPeaks/FinalSurge training plan auto-sync, multiple Apple Watch metrics pages, and Stryd custom metrics. Distribution is exclusively through the Apple App Store under a self-serve, product-led growth model with no field sales, no enterprise tier, and no disclosed institutional funding. The company relies on organic press coverage from endurance-sports publications (Runner's World, iMore, DC Rainmaker, Runblogger) and word-of-mouth among serious athletes rather than paid marketing. iSmoothRun holds no disclosed patents, has no published headcount or management team in the source data, and continues to receive app updates as of the last documented release in January 2021.
