Been there! I’ve researched and tested so many different apps. Spent hundreds of hours on it. Here is the final list of productivity apps I am using.
For task management – Nirvana task manager
For storing/organizing notes, ideas, etc. – Evernote
For bookmarks – Raindrop (similar to Pocket, but more user-friendly, with more advanced customization for your own needs)
For too many tabs – Chrome extension called OneTab.
For scheduling most important tasks – Google calendar
For files – Dropbox
I have well-though workflow between all of them, based loosely on Getting Things Done productivity method.
