Hi,

I am using CountDown and Chronograph looks nice, but very similar.  
(I looked previously at another [timer](https://community.homey.app/t/countdown-vs-countdown-timers/13896), but decided to move back to CountDown, due to lack of support and I prefer the flows to be uniform)

**Why did some of you move? Advantages/disadvantages?**

Thanks

Update (here’s my list, happy if you can add):

Chronograph:

- I can conveniently set hours, days, not only seconds (nice to have).
- You can create a device with the timer, although some reported it may create app stalling.
- A list of live timers can be found in the app configuration and can be paused/stopped.
- A timer created with a text variable containing the name cannot be used in a device (reported bug).

CountDown:

- I can edit the timer while it is running, it’s very useful for testing.
- The timer is available as a variable and can be read at any time, not only when the timer has stopped (Chronograph)
- Has no stopwatch and no transition.

PS. to add to the confusion, there are so many timer apps now, I guess a first thing to check is support by the developer. In Chronograph I did not see a reponse from the developer since Nov 2019 to some questions/bugs (but the app works and has happy users). Here are some other apps I was using:

Countdown by Ralf van Dooren are simple but effective. You have to create the Timer variable in the app and you can then use it in the flows, set the number of seconds (start/update) and stop it by setting 0 seconds. You can also manually set seconds in the app for testing purposes. The downside is that all your varia…
