Nuj is the FIRST alarm clock that uses money to motivate you to get out of bed! Featured in FastCompany: "There’s nothing quite like a little financially motivated fear to get you moving in the morning" — from "These 5 alarm apps are sure to wake you up" Featured on local NBC and CBS TV stations: "...might be just what you need to finally break the snooze button habit" — from "What the Tech: App of the Day" → How it works: 1. Set an alarm time, and a get up time 2. Add a challenge to prove you got up, e.g. a barcode you have to scan 3. Set a penalty 4. If you don't prove you got up by completing the challenge, e.g. scanning one of the barcodes, by the get up time, you get charged the penalty For example: 1. Set an alarm for 7:00am with a get up time of 7:05am 2. Add the toothpaste and shampoo barcodes 3. Add a $10 penalty 4. Alarm goes off at 7:00am 5. Get up and scan the toothpaste barcode before 7:05am. Or, don't, and lose $10 (goes to charity) → Have you ever turned your phone off to avoid getting up from a different alarm clock app? Nuj is the ONLY alarm clock that includes cheat detection by storing alarms in the cloud! No more cheap tricks! ↓ Wondering if it really works? Just read some of our reviews from ecstatic users! ↓
