Overview
Parallel brings Lebanon's six ski resorts into one app: Mzaar, Cedars, Laqlouq, Faqra, Zaarour and Qanat Bakish. Riders get a forecast for each mountain, 3D resort maps, a live map of their friends and a direct line to monitors and schools, in Arabic, English and French. Gabriel Ghoussoub leads the engineering for Parallel Inc.
Challenge
A day on the slopes means knowing the weather on that mountain, finding your friends across a resort and reaching an instructor. The app has to draw live positions on a 3D map on ordinary phones, keep working on a weak mobile signal and leave enough battery for the drive home.
Approach
We built one app for iOS and Android, with its own server, admin dashboard and public website, so a change reaches all of them quickly. The map draws pistes, lifts and each friend as a skier over the terrain. Sharing stays in the rider's hands: your squad sees you only after you check in, only at a ski resort, and each check in ends by itself after 8 hours.
Outcome
Parallel is getting ready for the App Store and Google Play ahead of the 2026 to 2027 ski season, and its website is live. On a Galaxy S10+, opening the app now takes 1.3 seconds instead of 2.4, and a phone at rest asks for no GPS at all, where it used to run GPS for 19 minutes an hour.
