"...runs very smoothly, it is super easy to start and restart timers, and the animation moving from regular to archived timers is fun" – iPhoneInCanada

"Cosmos Timer is great for those important reminders that you don’t need to be constantly aware of, which can clutter up calendars and to-do lists, and add to the stress of keeping track of tasks." -

Somewhat Useful

After looking at different timer apps, this one seemed to be the closest to what I want. It's not perfect, but it works well enough for me, but there are some features that could use work.

Setting the intial timer in using one time incrament (seconds, minutes, hours, days, weeks, months, years) is fine for short time periods, but if I want the time until a specific date, i.e. a birthday, that's usually not going to fall exactly on one of those time incraments. At that point you have to make a guess and then go back and edit the timer to the exact date. I would have put an exact date option when creating the app. Once this is added it will be a 5 star app.

Other then that flaw it seems to work pretty well. I haven't noticed an other problems with it.

Another option I would like though is the ability to dismiss the red alert counter on the home screen. I have multiple timers that count from a date, and I don't need the app to tell me this. Maybe add a tracker option so that the app won't think a specific timer has completed or at least will ignore it for the purpose of adding a red number to the home screen icon.

One of my most used apps

I have used this for years for various purposes. For example, when I buy a new durable product, I estimate how long I think it should last, then I set a countdown timer to keep track of how it is doing. Or I keep track of timed interval events like oil changes for the car or washing out the filter of the vacuum. Would like to be able to save my data to the cloud to prevent loss of any of my timers.

2.1.1 Version Doesn’t Work!

While the updated version of this app now has settings for both interval and time/date settings, it doesn’t allow you to create a countdown timer at all. Developers of this app, please get this fixed so we can continue to use it. Thanks!
