Simple Interval Timer Reviews

by M1CH43L

App has not been updated in ages, so the interface doesn’t work well with the latest OS. The sounds it makes are obnoxious and sadly not customizable. If I play music to an airplay device while using the timer, I lose the ability to adjust the timer volume. The Watch app also manages to disrupt the recording of exercises, so I have to use my phone for the timer and record my exercise with my watch, which shouldn’t be necessary. I have also observed that the timer function doesn’t even always keep accurate time: sometimes the interval is cut short.

Great interval timer! I like that the screen is green when it is “go time” and blue for the rest. My only complaint is that the vibration notification on Apple Watch is too light. I never feel it while I am running and doing interval training I wish it would beep in my headphones like the phone version does. It honestly makes the watch version pointless. If not for that, I would give it 5 stars!

Streamlined and functional, SimpleIntervalTimer works great on the iPhone, but needs Watch improvements. It needs a stronger haptic alarm for its Watch functionality, I have my haptic alert maxed out and I barely feel it when the timer goes off. I don't know what the setting for haptic alerts is with SimpleIntervalTimer, but it is much to low.

This interval timer works well with the iPhone both with or without headphones. Simple and easy to use. When I use it with Apple Watch it only has a vibration functionality in between sets. The IPhone has an audible beeping functionality that you can hear even if you have music playing in between sets. This is key as the vibration is not strong enough on the Watch when I’m running so I miss the intervals here and there which defeats the purpose.

This is just the sort of timer I was looking for. I like the repeat function, the changeable number of sets, and the break between each repeat. It would be nice if I could set the times in individual seconds instead of five seconds blocks, especially for the breaks. It’s nice to be able to have it on my watch so I don’t have to take my phone with me all the time.

SimpleIntervalTimer has everything I need for HIIT workouts. It’s simple and streamlined. Love it on my phone. My only complaint is that the watch notifications need to have a stronger vibration setting. I can barely feel it vibrate when working out with just my watch so I keep having to check on the timer to be sure I didn’t miss the rest periods.

I usually don’t write reviews but SimpleIntervalTimer has been on my phone for a very long time and has proven to be the best at what it does. Simple and to the point. I had to write a review for it. Creators, whatever you guys do, please do not take SimpleIntervalTimer away from us.

Thanks again!

no problem over the years until i tried to use it yesterday. (i use an interval timer infrequently... only when marathon training to conserve battery on my garmin). yesterday i fought it for 2 miles and finally shut it off. every time my phone locked it stopped timing. i had to unlock my phone for it to run and then as soon as my phone locked it stopped. frustrated, downloaded a different one to use going forward.

Love how simple SimpleIntervalTimer is. I like the new feature of the 5 configurations. Just one request, it seems not possible to edit the first 4, any changes just overwrite configuration 5.

App was great until they updated it for iOS13. It now continues to count in the background after you pause and move to another app. Only way to fix it is to power down the phone.

This is the only timer I’ve found that I can hear over my music and will positively alert me each interval and at the end.

One interest would be set interval sections. Interval 1: 1 min work 30 second rest. Do that 5 times. Interval 2: 2 minutes work with 1 minute rest. Do that 5 times.

That way we can just get into the next group without adjusting the timer. Other than that it’s the best I’ve found.

*recent update sort of solved this. Now it would nice to name the configuration a.

I love the simplicity and direct access to settings. I can’t figure out how to delete unused configurations, though. I will probably have to uninstall and then reinstall to get rid of them.

This is a simple, no nonsense HIIT timer. I use it. My kids use it. It truly fits the bill. All we need is 20 seconds on and 10 seconds rest— for eight sets total. Why this was so difficult to set up using other apps is beyond me. Most others with the unnecessary bells and whistles just fell flat.

by Jimsdoodles

This is my favorite app to use for fitness. I always said it to keep me on track when I’m working out. With this, I can get in and exercise with three muscle groups and five sets each in under 10 minutes

This is the timer you want if you are simply interested in timing. Adjustable active, rest, and repeat settings with excellent audio indicator that is easy to hear. The developer is very responsive in terms of answering questions about SimpleIntervalTimer .

I have been using SimpleIntervalTimer for years for running, body building and CrossFit. This is the easiest hiit app. It has audible beeps to prompt go and stop that can be heard over music. Just input your sets, work and rest times. It also has a 3 second countdown which I love. SimpleIntervalTimer is the best!

by JewelCR

It is one of the apps taking up the least amount of space on my device which is the main thing I was looking for. Setup is quick and simple, adjusting settings is obvious and user-friendly; easy app to use.

SimpleIntervalTimer is probably the best free, simple timer in SimpleIntervalTimer store. I don't use it on an apple watch, so I can't speak on that functionality. But, if you're looking for a simple timer that you can customize the number of sets and the length of each, just download SimpleIntervalTimer.

by Fit After50

this app is a fantastic free application for timing intervals. With well thought out rest and activity times and the ability to easily set up many different schedules, SimpleIntervalTimer is perfect for anyone who wants to either do interval training, or simply measure the time for different fitness activities. Highly recommended!

by Trainer Shan

SimpleIntervalTimer is great for all aspects of circuit training, tabata, or any interval training. I use it almost every day and appreciate the ease of understanding it from the get-go. I can safely recommend it to my clients of all ages as an uncomplicated tool for their at-home workouts.

by Cindaayyy

When I shut off the screen SimpleIntervalTimer will run for one interval and then stop completely. It will turn back on once I open my screen and it will pick up the last five seconds of the current interval as if it was counting the whole time. Made me think I was just being impatient but SimpleIntervalTimer is just faulty. I like to run with my screen turned off so I’m uninstalling.

by Spidog1975

I love the simplicity of SimpleIntervalTimer. I have used it for years. However, I sometimes have problems getting SimpleIntervalTimer to run correctly after an IOS update, like now. It’s frustrating, but the best simple interval timer I have found!

by Goidf

Been using this for a while. It can be a bit glitchy with the timer getting confused or stopping altogether if I’m using low battery mode. But overall it does the job.

by ZeroXnothinG

I've been using SimpleIntervalTimer for 3 years now. It's excellent for interval training. It's as it says, simple. Love the fact that it runs in the background while I listen to music. It is the perfect app for guiding an interval based workout.

by The Spin Stops Here

Love that I can use SimpleIntervalTimer independently on my watch! Very user friendly and I love not having to involve my phone. Settings are very easy to adjust on both the watch and the phone.

by Sunshine Kim

I use this timer for all my interval running. Easy to setup and customizable. It allows my music or Pandora to play in the background too.

by Chrisygetz

Finally a free app that doesn't limit the number of times you can use the timer before you have to pay! Worked perfectly for the circuit I use for working out. It was so nice not to have to reset a timer between each exercise. SimpleIntervalTimer also counts down the last three seconds so you know when to switch. Great app!

I’ve been looking for an easy to use interval timer and this is the one. I’m 63 and just discovered interval training. I use SimpleIntervalTimer with my ear buds because the gym is noisy. Thanks again!
