Québec City's bike-share charges you once a ride passes 30 or 45 minutes. Map apps ignore this limit. The planner splits your trip into several rides on the same bike. You re-dock along the way, and the clock resets. The planner also accounts for hills.

Result: across 1,000 sampled trips, overage charges dropped from 49.6% of trips to 0%.
