DuoSwim: Swim Workout App 4+

Overall great app. I signed up for a free trial and after using 3 times bought a year’s subscription. Three areas I’d like to see improvements. One, the ability to see on my watch what is coming up next. I don’t see the next set until the final 10 seconds begin to count down and, if I need to put on or take off fins for example, I fall behind. Second, if I do fall behind it would be great to be able to pause or restart the set. As it is, I just usually skip one interval to get back on track. And lastly, sending the workouts to my watch (Apple SE) is glitchy at times and I need to reset the watch and/or my phone (has happened twice in the first 4x using it). But overall great and something I expect to use ongoing.

Hi, thanks for your excellent feedback, we really appreciate it. We have some great news! The development team are working hard to implement adjustable turnaround times and rest periods. This will be made available soon. We will keep you updated with our progress.

In terms of your other points, I will pass your feedback onto the development team for further investigation. Happy swimming!

After using this for around a month, I switched back to MySwimPro since their system is smoother, but I genuinely love what Duo is doing by competing with SwimPro. There’s just a few things this app does that, if added or fixed, would make this THE swim app, undercutting SwimPro:

- On a guided workout, there’s no way to resync the watch timer with your pool’s pace clock. If you accidentally start it not exactly on the :57, you need to rely on the watch’s timer or be off set the entire workout. The same is true of if something in the lane takes you off pace (someone joins the lane, choking on water, suit malfunction, etc); you’re just stuck. Adding a “restart set” or “restart rep” button would be a massive improvement.

- The sets themselves are solid, excellent even. The problem is that the training path sets don’t change (or mine is bugged) from day to day; I was on Varying Pace for three days before I juststarted using the set library.

- Tracking is inconsistent, more inconsistent than using the Apple Watch’s swim workout tracking alone. A 1400yd swim might be recorded as 1000yd, heart rate data isn’t recorded, times are wrong sometimes… It’s just janky. Sending a workout to the watch takes a few tries, but I don’t fault Duo for this since every phone-watch connected app has this problem from time to time.

Swim Duo is an excellent app and what they’re doing is important; it just needs another round of deep cleaning. I’ll be back‽

Hi, thank you for your excellent feedback and sharing it with us. We really appreciate you taking the time to review DuoSwim and provide us with such detailed feedback, this is what makes our app better.

We’ve got a lot of improvements coming in v4 of DuoSwim which aligns well with your swimming requirements. We would love to know more about your needs around the timer and how we can help sync with an external timer on poolside. If you would like to chat about this, please send an email to our team at feedback@duoswim.com.

We’re sorry that you experienced a bug with your Personal Training Journey. We have fixed this issue, so you will now be able to move on from Varying Pace when you’ve completed that workout.

In terms of your third point, I’ve passed your feedback onto the development team for further investigation. We use Apple’s Watch sensors to track your swim so it might be a permissions issue that prevented you from seeing your heart rate etc. We will keep you updated.

This app has everything you need to improve your swimming, whatever skill level you are currently at. With an easy-to-use interface, excellent features, and top-class advice, it’s got all you need to succeed in the pool. Would highly recommend if you want to become a better swimmer!

Hi, thanks for your feedback and for sharing it with us. We are delighted you like the app. 😀
