Never miss your stop again — the commuter's nap guardian Ever wanted to close your eyes on the bus or train, but couldn't risk waking up three stops too late? Sleep Tight On Board exists for exactly that anxiety — and now there's a thoroughly jaded salted fish napping alongside you. Why this one? Location-precise wake-up. A high-accuracy geofence triggers a strong vibration and alarm the moment you enter your destination zone, with speed-aware early warning so fast stretches don't catch you out. Battery-smart tracking. GPS runs light while you're far out and only switches to high accuracy as you approach — long commutes included. Signal-loss protection. In tunnels and underground sections where GPS drops, it estimates from your last known speed. It would rather wake you early than let you overshoot. Raise a jaded salted fish. Waking up on time and getting off on time is how you feed it. It grows, changes expression, judges you, and reluctantly says something whenever you dismiss an alarm. Six moods with 120 lines each — 720 in total, written from scratch in all five languages, not translated. 76 accessories. One drawn automatically per level, across head, face, chest and hand, in five rarities. Draws are earned in-app for free only — never sold, never purchasable — and the odds are fully disclosed. Play with it, or be woken by it. Whack-a-fish, rock-paper-scissors, tic-tac-toe and gomoku, three games a day. Any of them can be set as your wake-up challenge: beat the fish or the alarm keeps ringing. Daily tarot. The full public-domain Rider-Waite deck. The fish comments based on the card and its own mood. The worst fortune grants the most EXP — your bad luck is its nutrition. Home screen widget & Dynamic Island. Start monitoring a saved place with one tap and watch the remaining distance live, without opening the app. Core features: Draw your wake-up radius directly on the map — works for metro, bus and rail Background monitoring with the screen off, so you can actually put the phone down Custom alarm sound from your own MP3s Long-press shortcuts, time alarms, white-noise sleep mode
