Doze off on the ride? A very grumpy little shark wakes you before your stop. Get off on time and it grows and judges you. It also keeps your to-dos, calendar and shift roster, and briefs you every morning. Nurse, retail or factory shift worker? Fill in your shifts and your alarms follow them. Grumpy Sharky: an arrival alarm, a pet to raise, to-dos, a calendar and a shift roster in one. Gets you off at the right stop - GPS only, no route lookup: buses, subways, trains, coaches and ferries, in the countryside or abroad - Vibration and sound as you enter your destination's range, earlier when you're moving fast - Battery friendly: light tracking far away, high accuracy up close, works with the screen off - Tunnel protection: no GPS? It estimates from your last speed and would rather wake you early - Your destination gets a little red flag. Ride the same way long enough and little sea creatures show up along it. Tap one: it remembers how often you've passed Take care of Sharky - Dismiss alarms on time, get off at your stop, finish your to-dos, and Sharky grows, levels up and changes its mood - It poops, gets sick, sleeps at night and talks in its sleep - Six moods and 10,000+ lines, written fresh in five languages, not translated - 77 accessories: one per level, free in the app only, never sold, odds published - Pink Shark: a new look at Lv10. Sharp tongue, soft heart, would never admit it - Play with a friend: scan each other's QR codes and your sharks sit face to face and really chat. Your friend sees your shark's current look To-dos and calendar - Dates, reminder times and repeats (daily, weekly, monthly, yearly, or only on workdays or days off) - Location reminders when you arrive at or leave a place: documents at work, milk when you leave the store - Remind me when I ride: no date needed. Start a ride and Sharky tells you what to do on the way - Countdowns for exams, trips and bills, with Sharky teasing you 7, 3 and 1 day before - Sticky-note colors for what's urgent, plus notes, phone and address on any to-do - A month view with a green dot on days you finished everything. Overdue to-dos get stuck on Sharky - Tap Done or Remind me in 10 min right from the notification - Back up your to-dos to a file for your next phone. No account needed Shift roster, made for shift work - Three ways to work: a regular week (public holidays off), a fixed rotation (like 2-on-2-off) or a monthly roster from your manager - Fill it like coloring: pick a shift and drag across the days, or fill one day after another - Doubles: a day shift straight into nights shows as two colors in one box - Copy last month by date or by weekday, with undo - Mark vacation, sick, personal and official leave - Different hours on different days? Change just that day - Monthly summary: how many of each shift and your total hours - Add your hourly wage for an estimated paycheck, with shift bonuses, overtime and currency (before tax) - Share your roster as an image, portrait for phones or landscape for computers, with your to-dos if you like. Showing your pay is up to you - Alarms and to-dos can ring only on workdays, days off or a certain shift, or "X minutes before work" - The widget shows today's and tomorrow's shift - Packed month or empty one, Sharky has something to say Sharky's briefing - Each morning Sharky grabs a pointer and briefs you on today's to-dos, what's overdue and what's done - Save a day's agenda as an image to share with family - Weekly report: to-dos done, rides taken and distance traveled, charted Holidays - Christian holidays like Easter and Christmas, one tap to get reminded And more - Home screen widget with Sharky; the large size lists today's to-dos. Start monitoring in one tap - Daily tarot, whack-a-mole, rock-paper-scissors, tic-tac-toe and gomoku, also as wake-up challenges - Time alarms, white noise, custom ringtones, headphones mode and quiet hours Your to-dos, roster and pay stay on your phone and are never uploaded.
