Cargo Sim
Read full descriptionHide full description
Run a delivery fleet across real-world maps. Pick up cargo, dispatch trucks to depots, refuel at petrol stations, recharge EVs at fast chargers — every route is calculated against real road data. Each day brings three premium daily contracts that pay several times a normal delivery and expire at midnight. Complete all three to earn the Perfect Day achievement and challenge a friend through Game Center to do the same. Trucks come in four flavours — diesel and electric — each with its own range, speed, capacity, and emissions profile. EVs are cheaper to charge and friendlier to the climate; diesels go further per tank. Higher-end trucks can carry up to 2 or 3 cargo loads simultaneously for optimized routing! FEATURES • Tap-to-select dispatch on real San Francisco and Munich maps • Multi-cargo dispatching on premium trucks • Three daily contracts with weekly leaderboards • Diesel and EV trucks with distinct economies • Auto-detour refuel and tow recovery • Real-time catch-up while you're away • Game Center leaderboards including a weekly distance race • Achievements: First EV, 1,000 km, 10,000 km, Perfect Day, and more • Local notifications for arrivals and contract deadlines • Native SwiftUI on iPhone, iPad, and Mac Unlock Munich using your hard-earned delivery fees. More cities coming in future updates.
Underline
Read full descriptionHide full description
Underline is a metro builder set in real cities. Pick a city and draw lines across it. Every station you place sits somewhere real, and the passengers who use it are where people actually live and work — the map is built from real population and employment data, so demand isn't invented. Put a station where nobody is, and nobody rides. Choose how each stretch gets built. Tunnel under expensive ground, run elevated, or stay on the surface where there is room. Set how often trains run and how long they are, then watch people find their way across your network — and watch the crowding when you have got it wrong. • 35 cities across five continents, from London to Tokyo to São Paulo • Demand modelled from real population and employment data • Tunnel, elevated and surface track, each with its own cost • Ridership, crowding, revenue and running costs tracked day by day • 110 commissions to complete, from straightforward to genuinely hard • No account, no ads, no tracking, and it works entirely offline • Interface in nineteen languages Five cities — one on each continent — are free, along with fifty of the commissions. A single payment unlocks every other city, the commissions set in them, and unlimited budget if you would rather just build.

Verdict
The clearest difference is in-app purchases: Cargo Sim at none against Underline's 10. Underline's advantage is update cadence (every 2 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
