Disclaimer: This is my startup.

We're building Jell (https://jell.com) to tackle this problem. We have 2 sets of core functionality: OKR tracking, and "checkins" which can act as a daily/weekly/monthly "standup".

You can add plans/tasks to your checkins (and mark them as complete), and link these items to your OKR's.

We've seen a lot of companies have success with our tool (many replacing daily standups with it). We'd love feedback.
