Interval Timer □ HIIT Timer

30
Value score / 100 Worth paying? No Skip it

This app is generally well-regarded for its simplicity and effectiveness as an interval timer, but a recent change to a paywall after one or two uses has led to significant user dissatisfaction and makes it not worth paying for given the available free alternatives.

Free + in-app purchases seen up to $35.99 4.8★ lifetime (85,250) since 2016

Interval Timer by Float Tech is praised for its simple, user-friendly interface and effectiveness as a workout timer, allowing background music and customizable intervals R2R6R8R12. However, many recent reviews highlight a new paywall that restricts usage to one or two free sessions before requiring a subscription, leading to widespread complaints about deceptive pricing and high costs for a basic timer R1R3R7R9.

Free vs paid

The app is marketed as free to download, and historically offered basic timer functions without payment R2. However, many recent reviews indicate that the free version now only allows one or two uses, or one use per day/month, before a paywall is enforced, requiring a subscription or a lifetime purchase R1R3R7R9. The paid 'Premium Pass' or lifetime purchase offers unlimited use and customization features R5R8R44R49, though some users find the customization options limited even after paying R5R69R75R93.

Value complaints

  • The app is not truly free and imposes a paywall after only one or two uses, or one use per day/month, which users find deceptive.R1R3R7R9
  • Users consider the subscription or lifetime purchase price (e.g., $20, $3/month, $8) to be too high for a simple timer app.R15R22R34R39
  • The paid 'Premium Pass' or lifetime purchase does not offer enough customization, such as varying exercise durations within a round or saving multiple workout profiles, to justify its cost.R5R69R75R93

Where it delivers

  • The app is easy to use, has a great interface, and is simple and straightforward for basic interval timing.R2R5R6R8
  • It allows users to play music in the background and provides clear audio cues over the music, enhancing the workout experience.R12R40R56R72
  • The app is effective for various types of workouts, including HIIT, running, and general exercise, helping users stay on track.R6R8R11R20
  • It offers customizable work and rest intervals, as well as the number of rounds, providing flexibility for different routines.R8R44R49R51
Worth paying if

It might be worth paying if you value a simple, ad-free interval timer that integrates well with background music and you find its current feature set sufficient for your specific workout needs R6R12. This is particularly true if you need a timer that announces intervals over music and you don't require complex, varied interval structures R12R40R56R72.

Skip / stay free if

You should skip paying if you expect a truly free app for basic timer functions, as it now has a strict paywall after minimal use R1R3R7R9. Also skip if you need advanced customization like different exercise durations within a single round, the ability to save multiple workout profiles, or a countdown out of rest periods, as these features are often cited as missing or limited even in the paid version R5R4R69R75.

Evidence note: The lifetime rating of 4.8 from 85,250 ratings is significantly higher than what recent reviews suggest. This discrepancy is due to a recent change in monetization strategy, where the app, previously free for basic use, now enforces a paywall after one or two uses. Many positive reviews predate this change, while recent reviews are heavily skewed negative due to the unexpected paywall.

  1. [R1] 1/5 · US Not free: Used 1 time and the timer worked then went to use again and it kept trying to get me to pay for use or do the free trial before I pay. Free for 1 use maybe
  2. [R3] 1/5 · US Pay to use - don’t be fooled: This timer works once but requires a subscription after that. Not very transparent of them.
  3. [R7] 1/5 · US Paid App After 1 Workout: I only got one timer session done then it wanted me to pay to continue using the app. Free download but pay to use is deceptive. Just make it paid upfront if there’s a limit to the basic use of the app without payment.
  4. [R9] 1/5 · US Makes you pay: I used it for my workout for the first day, the next day I tried to do it again but it would let me without paying for it. Don’t waste your time or money
  5. [R15] 1/5 · US Have to pay to use: Use to not have to pay but now you do. A life time purchase for this is NOT worth $20 more like $10
  6. [R22] 1/5 · US subscription required: a TIMER APP requires a subscription to use? or $20 to buy a timer? absolutely insane
  7. [R34] 2/5 · US Great until…: This app worked great until it suddenly required a paid subscription to use when it used to be free. $20 for a timer?!
  8. [R39] 1/5 · US Money grab: Monthly subscriptions for a simple timer is a scam
  9. [R5] 3/5 · US Paying for Premium Pass doesn't offer much customization!!!: The app is user-friendly and free of Ads, but you can’t customize the work time per exercise within a single round. All exercises must have the same duration, which is a big limitation if you're looking to customize the rounds more. Therefore, bare in mind that it's mainly Tabata format, even after purchasing the premium pass!!
  10. [R69] 1/5 · US Terrible if wanting to do anything complicated like 4 x 4: I subscribed to this. I had a very small sequence of events that I needed to do and then I tried to create another, and it was impossible to do. The interface is really no intuitive and needs to be fixed. We need to be able to add our exercise exercises in order set how much time for each and then have the intervals it’s just ridiculous ho
  11. [R75] 2/5 · US Can't have multiple different rest/work times: A quick tutorial on the app would be nice. But mostly you can only have your working sets and rests be a specific amount of time. It would be far better if you could queue up a five minute workout followed by a 30 second rest, a 10 minute workout followed by a two minute rest, etc. But it doesn't seem to have that very basic feature
  12. [R93] 3/5 · US Need another feature: I am looking to do thee sets of a exercise then move to next set of three. I want short rest the a slightly longer rest between sets. What don’t I comprehend ?
  13. [R2] 5/5 · US Great workout timer: Hard to beat for a free timer. Easy to use, great interface.
  14. [R6] 5/5 · US Made me want to workout: I hate counting reps in my head with jump rope. I love how the alarm is subtle & not annoying. I’m only working out because of this app. It’s really convenient for anyone who gyms. GOATED APP
  15. [R8] 5/5 · US Great for exercise timing: Has great features that lets you personalize your exercise to benefit you
  16. [R12] 5/5 · US Simple and smart: Easy to use. Straight forward. You can listen to music in the background from the same device and the app will talk over it when counting down.
  17. [R40] 5/5 · US No annoying tick: Allowed me to play music full volume.
  18. [R56] 5/5 · US Good: Happy it plays with my music
  19. [R72] 5/5 · US Exactly what I was looking for: I was looking for an app that would allow me to time sections of Cold plunges and cold showers without interfering with my music. This app works perfectly for me.
  20. [R11] 5/5 · US Great interval timer: Great for a novice interval runner like myself. Programmers, please add last 5-minute warning to start cool down. :)
  21. [R20] 5/5 · US Perfecto: This schedule timer works perfectly for my 10 minute morning routine.
  22. [R44] 5/5 · US Perfect: Awesome timer. You can adjust times and rounds.
  23. [R49] 5/5 · US Exactly What I Was Looking For: Easy to navigate. Multiple options to apply to workouts. Wish I had found you 5 years ago
  24. [R51] 4/5 · US Great app! Little quiet: I love the way it works! Let’s you adjust the work interval and the rest interval. Let’s you decide how many intervals. Gives a 3 second countdown to both rest and work and also does a “halfway there” during the work part! Big fan. I just wish you could change the volume because I can only find on/off and a couple times I missed the mark because i couldn’t hear it over my
  25. [R4] 2/5 · US Too touchy: Great idea, but could be designed better. I need a way to time one minute of running (“Work”) followed by three minutes of walking (“Rest”), X10. Problem I am having is it’s too easy to accidentally make something unpredictable occur like skipping to the next section or stopping the timer altogether. Ideally if I could turn off the screen and allow the app to run in the background, tha
  26. [R23] 3/5 · US 90% of time perfect: I run three minutes and then walk one, I do about 20 miles a week on this schedule and I know that I can run .3-.4 in three minutes depending on how deep I am. Well sometimes the timer just decides to freeze and i will of made a lap around my track but the timer is just sitting there with two minutes left on the work out section. Extremely irratatimg when you're trying to buil
  27. [R61] 2/5 · US Audio stopped: Love this app but the audio indication that the interval is over doesn’t work most of the time. I’m not looking at my phone, so that’s a fail.
  28. [R50] 3/5 · US It’s almost amazing: The work out timer and all that is amazing, but you have to pay after the first go. I don’t think it’s worth $20
  29. [R53] 1/5 · US $20 for a timer?: I find the in-app purchase price of $20 for a timer to be ridiculous.
