Sick of scrambling to scribble something down in your notes app, only to be unable to find said scribble when you need it days, weeks or months down the line? Samesies. That’s why KFX Tech has developed Write Chaos, a sleak, simple to use app which allows you to quickly find specific notes based on when you wrote them and which words you used. Whether it's a genius business idea or a wild dream you need to remember, jot it down in seconds and let Write Chaos worry about keeping your notes organised. Write Chaos allows you to sort & filter your text by the date, time and length of the note, as well as the giving you the ability to search through all of your notes for specific phrases. This means you can easily find that half asleep screenplay idea you had and the killer app idea you wrote down that will probably end up netting you about $5 in revenue... d'oh! Anyway... as someone who loves to make too many notes I often finding myself searching back through weeks, months and years worth of notes to find the idea or important piece of information I'm thinking of. This app lets you add notes quickly and chaotically, safe in the knowledge that you can search, sort and filter at any later date when you need it. I basically made this app for myself, but hopefully it's of use to you too! Download for free today and never lose a note again.
