With WS Tasks you can create and manage your personal tasks, as well as enter amounts for each of them, share them with friends, create polls, synchronize the tasks in multiple devices or see the changes made by your friends on each task in real time. Are you meeting your friends for a bbq but you have to buy too much stuff? With WS Tasks you can create a task with sub-tasks and share them with your friends. Each friend will be responsible for assigning these tasks and entering the cost of the task. WS Tasks will automatically calculate how much each friend has contributed and how much each one has to pay. A quick and easy way to settle accounts. Does a friend not have the application? No problem, you can indicate the total number of participants even if they don't have the application installed, and in this way WS Tasks will calculate how much each participant owes or how much has to be paid to a specific friend.

A frictionless capture pad for the ideas you would otherwise lose. If you have ever woken at 3 AM with a great idea and nothing to write it on, or watched a brilliant phrase evaporate while you opened a heavier app, Fast Idea Book is for you. It is a calm, on-device idea book built around one job — capture the thought before it fades — and one principle: never make you wait or sign in. Open the app and you are already typing. Quick notes save with a single keystroke. Brainstorm freely without folder rituals, then tag entries afterward when your brain wants structure. Voice memo capture for hands-free moments, brain-dump templates for foggy mornings, and a search that surfaces the half-remembered note in seconds. Home Screen and Lock Screen widgets keep the latest idea visible, and the interface ships in 39 languages with full accessibility. Built for writers, founders, students, designers and anyone whose best ideas arrive at the worst possible moment.
