Potential users are not going to register for an account in order to determine if your app is the rare and possibly mythical great task management app, or if it is instead the statistically far more likely not great task management app. You know and believe it is in the great category. Potential visitors do however need to be shown that greatness.
Your landing page needs to communicate enough value for visitors to be willing to invest their time in it. Your "Get started" button seems to offer the promise of revealing that value, under the possibly over-optimistic assumption that the visitor will immediately detect that greatness without it being explained or shown to them first, something that only happens in the most extreme of cases where the greatness is immediately obvious in the first few seconds of interacting with an app, and which is rarely the case for task management apps.
