In 2024, Oxford made “brain rot” the word of the year. The term means long, mindless scrolling on social media. But are social media really that bad? They still help us work, connect, and study. We believe the key is balance. Taskfulness helps you keep valuable interactions while limiting the doomscrolling. The results: our members save 28-36% of their screen time daily, without missing out. Want intentional screen time? Try Taskfulness free for 7 days. Built on Cognitive Behaviour Therapy principles.


 HOW IT WORKS 1. Pick an app 
 Select the apps that steal most of your time. For example, Instagram, WhatsApp, Reddit, Gmail, etc. 2. Set intention 
 Each time you open a chosen app, Taskfulness will pop up and ask: “Why do you need it?” and “For how long?”. Once you enter the reason, the app opens. 3. Stay focused* 
 Use the app for the duration you set. Mid-session, you’ll get a quick reminder of your original intention. When time’s up, the app closes automatically. 
 *works only with Reminders on WHY TASKFULNESS

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?
