I have personal used multiple apps for setting goals and tasks but didn’t find any app that can work like an OKR. Vision is a unique app that functions exactly like an OKR and let’s you set goals and associate results to it. It even let’s you add task and link them to a goal. This allows to visually track your goal. The only problem I encountered is that the sync doesn’t work as expected between the desktop and mobile app and the app also seems a bot buggy and unpolished. The addition of a pomodoro clock, time tracking and habit tracking will make this the best app for goal setting.
