Perfect for my job

When I first got this app it worked great but now after 63 reps the timer stops going off. Also is there a way to turn the Apple Watch function off? I don’t always feel the vibration and much prefer the sound through my headphones so I don’t over water any of the 1000 plants I take care of at work.

Your App saved my eye

I have had Ramsay Hunt Syndrome (Bell’s Palsy plus ear shingles) since February, and my eye was “hinged” open until recently, and I bought this $1.99 app, and it alerts me on my iWatch or iPhone to blink every 57 seconds, over and over, and this product helped me regain the ability to blink naturally. Thank you from a a guy that can naturally blink again. Go without blinking for 2 minutes and see what I mean. It gets dry. Blinking saves the day. I am Hank Hurst, and I was not paid a red cent to make this review.

Simply just works!

Hi Vlad, wanted to thank you for this app. It works perfectly in the background with any app I’m working on and even when I close iPad it’s still there reminding me if I want it to. I was using free version which is fine but upgraded so I could support your work, didn’t need the customization but it may be useful to play with in the future. $1.99 is very reasonable for such a useful app, thanks!
