About this app

Not just a schedule. A real-time timeline for your driving day. Designed and developed by a bus driver, based on real daily experience behind the wheel. This app shows how a driver’s workday actually unfolds — not how it looks on paper. — KEY FEATURES — Timeline-based duty view See your entire duty as one continuous flow, including pre- and post-duty time. Vehicle change tracking Record multiple vehicles within a single duty and see exact boarding and alighting times. Next departure countdown Always know how much time is left until your next departure. Break time awareness Planned breaks adjust automatically when the previous duty runs late. Diversion and route information Check active diversions per line with detailed route information. Smart notifications Get reminders 20, 10, and 5 minutes before departure. — WHY THIS APP IS DIFFERENT — Most scheduling apps are built from an office perspective. This app is built from the driver’s seat. It focuses on the moments that actually matter during a shift — tight connections, reduced breaks, and the pressure before the next departure. — WHO THIS APP IS FOR — Bus drivers working with vehicle changes Drivers with split duties or variable breaks Anyone who wants to see their workday instead of just reading a schedule A tool shaped by real driving — not assumptions.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
