Looking for VoiceOver testers for Flip Unit - Free accessible unit converter

Hi everyone,

I'm a developer who has built a free unit converter app called Flip Unit with accessibility as a core priority, not an afterthought. I'd really appreciate feedback from VoiceOver users to make sure I've done it right before the public launch.

The app includes:
- 6 conversion categories: Cooking, Currency, Distance, Temperature, Weight, and Area
- Full VoiceOver support with clear labels and announcements
- Dynamic Type support (all text sizes)
- High contrast mode
- 162+ live currencies
- Smart cooking conversions (ingredient-specific, like cups of flour to grams)

This is a passion project and will remain free forever - no ads, no tracking, no in-app purchases, no premium tiers, no data collection. I built this because most unit converters have poor accessibility, and I wanted to create something that works for everyone.

If you're willing to help test, you can join via TestFlight here:

You can also learn more about the app at https://flipunit.app (note: the App Store download links on the website won't work yet as the app is still in beta)

I'd especially love feedback on:
- Whether VoiceOver navigation makes sense
- If any labels are unclear or confusing
- Any issues with the unit picker/selection screens

Thank you for any help you can offer.

I haven’t necessarily tried all the conversion units, but I did try the temperature and distance units, and they’re looking very good.

One thing I’d like to see is this: when selecting the conversion units, clicking the button to open the dropdown list can remain the same, but would it also be possible to add the conversion units as VoiceOver actions so we can reach them just by swiping up or down for quick access? Another option could be to make conversion units appear via swipe up or down only if we set them as favorites, so we would only see our favorite or most frequently used units. It’s a great app, thanks so much for the work.

That's a really helpful suggestion about VoiceOver actions. I hadn't considered adding swipe up/down to cycle through units directly - that would definitely be faster than opening the picker each time.

I'll look into implementing this, perhaps with the most frequently used or favourite units as you suggested. It's exactly the kind of feedback I was hoping for.

Thanks again for taking the time to test and share your thoughts!

Hi, Siraj.
A very nice app. Very well laid out. I want to make a couple of points. In the temperature conversion section, I could not use zero as a value even though zero is a valid temperature. Also, I did not find a way to insert negative values since I couldn’t find the minus sign in that keyboard layout. Great work! I can see myself using this app quite a bit.

Hi Theepan,

Thank you so much for the kind words and for catching these issues - I'm a bit embarrassed I missed something so obvious! Zero and negative values are essential for temperature conversions.

I'll get both fixed in the next update. Really appreciate you taking the time to test so thoroughly.
