Musekit is a one-person studio. I design and develop apps that help with reading, writing, and organizing ideas. I build what I actually use, and keep refining them over time.
Requote helps you collect and revisit highlights from books, articles, and other sources. Save quotes, organize them with tags, and use the shuffle feature to resurface old notes when you need them. It's simple: capture fast, find later, and let past highlights support your current work.Sumof helps you keep track of what you own and how much. Toothpaste tubes in different drawers, onions in the fridge, books you're not sure you already have. Add items, note where they are, and see your total at a glance. It's for anyone who'd rather check an app than buy something they already own.More apps to come.
