Pros

This is great for scheduling training and other types of important items. I really enjoyed how quickly you could merge this with an e-mail and send out.

My overall experience with Calendly is excellent. It is an amazing to automatically create schedules during the week.

CA

Clayton A.

In general, setting aside the previous comments has been a good and useful tool. I think in combination with a kind of Doodle system could be great.

SM

Soledad M.

Pros

The app is very easy to use and allows you different options on how you would like to dual authenticate your login. The speed and reliability of this app are great as well.

RC

Rachel C.

We needed a good solution to increase our security for signing onto our server, and Duo is great for that.

I like the simplicity of the multifactor authentication process. It was easy to deploy on our phones and works perfectly each day.

SR

Cons

Disappointed with this and strongly recommend against going down this road. The Outlook integration is broken, the patch does not work.

KC

KYLE C.

Honestly cant think of much to dislike. The only thing that comes to mind is that sometimes the app that is supposed to sync my outlook calendar with my Calendly will crash for no reason.

I got a little confused at one point when people were unable to schedule time with me because the time for the appointment was too close to the time of scheduling.

Cons

They have acknowledged that this is their mistake and they need to fix it, but they seem incapable of doing so.

KD

Krishna D.

The downside is that it gets really annoying after a while. All the texts, confirmations, multiple logins, etc. get overwhelming when you just want to check something really quick.

LM

Lia M.

The only real downside to Duo is that each employee has to install it on their personal smartphone, and some people don't like that.
