OpenTodoList is a todo list and note taking application. Organize todo lists, notes and images in libraries, which can be stored either completely local on the device you are working on (and hence ensure no information leaks out to untrusted third parties) or use the built in synchronization features which allows you to synchronize your libraries across devices using your self-hosted NextCloud or ownCloud server, other WebDAV servers or Dropbox. In addition, a library is just a directory holding the items of your library as simple files - this allows you to use any kind of third party synchronization tool to sync your information.

Add up to 5 daily tasks by tapping the blue plus, then tap to complete or swipe left for 5-minute reminders. Each new day automatically gives you a fresh, clean slate to focus on what matters most. While other task apps overwhelm you with endless features and infinite task lists, Simple5 embraces the power of constraints. You're limited to just 5 tasks per day - not as a restriction, but as liberation from digital clutter and decision paralysis. This isn't random - it's based on cognitive science showing our brains can effectively prioritize maximum 5 items at once. When you can only choose 5 things, you automatically choose the RIGHT 5 things. When adding your tasks, you naturally consider the most important things you want to do. The app relies on that. Furthermore, you cannot delete your tasks once they have been written down. This is because it is not possible to "delete" something that has been written down with pen and paper. Choose how you want to spend your time wisely! Add up to 5 daily tasks by tapping the blue plus, then tap to complete or swipe left for 5-minute reminders. Each new day automatically gives you a fresh, clean slate to focus on what matters most. Key Features: * 5-task daily limit forces real prioritization * Automatic priority numbering (1-5) * Daily reset - no overwhelming backlog * Tap to complete, swipe for reminders * Built-in tutorial for instant understanding * Share your daily list as simple text * Clean, distraction-free design Why should I spend money: * No Subscriptions - Pay once, own forever * No Ads - Completely clean experience * Privacy First - Your tasks stay on your device * Thoughtful Design - Every detail carefully crafted * Quality Focus - Built for effectiveness, not feature bloat
