Lost signal? Make the wait count. You're on a train, scrolling through a webpage — then everything freezes. You've entered a tunnel, and your phone has lost its connection. Instead of staring at a loading spinner, open this app and put that idle time to good use with quick-fire mental math. Solve everyday arithmetic — the kind you actually use in real life, like totalling up a restaurant bill, working out a tip, or figuring out a discount at the shops. Race against a computer opponent and see how many you can get right before time runs out. Here's the clever part: the computer's speed is tied to your network signal. When your connection is weak or gone, the computer slows right down, giving you a fair fight. The moment your signal comes back, the computer speeds up dramatically — so fast that you'll almost certainly lose. That sudden loss is your cue: the internet is back, and you can pick up right where you left off. No time wasted waiting. No time lost switching back. Just a few minutes of genuinely useful brain training in between. FEATURES - Real-life arithmetic: addition, subtraction, multiplication, and division problems inspired by everyday scenarios - 9 difficulty levels, from beginner to expert - A computer opponent whose speed adapts to your real-time network latency - Automatic signal recovery alert — lose to the computer and you know you're back online - Global leaderboard ranked by mobile network operator - Multilingual support for 20+ languages - Dark mode and adjustable font size - No sign-up required — just open and play
