Span is a calm, physics-driven bridge builder. Draw a bridge across the gap, choose your materials, then press Test and watch it carry the load — or buckle in glorious slow motion. Every beam glows with the forces running through it: a live X-ray of tension and compression, so you can see exactly why it held, or why it snapped. Rewind, move one strut, try again. • 57 hand-built levels across eight worlds — timber valleys to ocean straits • Timber, steel, stone, cables and road & rail decks • Real hazards: wind, earthquakes, thermal stress and floods • Drawbridges, canal locks, trains and passing ships • God-mode Sandbox: unlimited budget, every material, every disaster • Level editor: sculpt terrain, place anchors, schedule the traffic • One-tap replay export — share your best holds and worst fails No ads.

Verdict

The call

The clearest difference is in-app purchases: Bad Bridge at none against Span's 1. Bad Bridge also leads on iOS requirement (15.0 vs 17.0). Span's advantage is ads (none vs shown) and update cadence (every 5 days vs every 2 months). On price and device support there is nothing between them.
