"...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." -

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!


Best Countdown App IMO

This is definitely the best countdown app I have ever used. I have been using this app for several years now and it works perfectly. I use it for reminders for events such as birthdays, holidays, bill payments, and when to refill my medications. The thing that sets this app apart from others is that you can set a countdown based on a certain amount of years, months, weeks, days, hours, or minutes instead of having to know the exact date of the end event. This is super useful for me, especially when setting a reminder for when to reorder my meds. I have not seen this feature in other countdown apps. I do hope the developers consider updating the app. It has been a while since it was last updated. I would be devastated if the app stopped working one day after I update my iPhone to a new iOS. I use this for many reminders, so I would be at a loss if it stopped working! The other great feature about this app that I have not seen with others is the ability to save a reminder that was set on a specific time length and not an end date. If you have a timer set for a time length (years, months, days, etc.), there will be a gray star in the upper left hand side of the timer's page. If you click the star, it will turn blue. That means that the timer has been saved and can be used again in the future. I use this for my med refills. Works like a charm!

ETA: Thank you for updating the app!!! 😊


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.
