Rudy, thanks for your feedback.
We frequently extend the free trial for anybody who asks, so had you contacted us we would have gladly provided more time. I noticed that you've only had the trial for just 1 day - the free trial provides all premium functionality so I would really appreciate knowing what more you would find useful.
Checking your account I can see that you only have 1 workspace so there would be no need to change workspaces in such a situation.
We are unaware of any issues with the mobile app, but certainly, if you were to provide some info on what you experienced, we would investigate immediately.
If you've any interest, I'd be more than happy to talk to you more about how todo.vu works via email or a phone call.
Either way, I wish you all the best.
