* Slider haptics: dragging the Blood Sugar slider now gives tactile ticks, with a stronger pulse when crossing Low, Normal, Pre-diabetic, or Diabetic boundaries. * Miles now live in the Imperial section with feet, inches, and yards, right where you'd expect them.

This tool has been on the first page of my phone apps for many years. It's earned that precious spot because I use it all the time. With all the new conversations in V2, like fractions and angles, it's even better. Seriously useful.

Response from developer

Love to hear it! Thank you so much for the 5 stars! ❤️🫵🏼

Great app for converting

I use this at least a couple of times a week, depending on what I'm doing.

Essential App

This is one of my most used apps. I’ve been using the PRO version for a couple of years now, and I would happily pay for it again.
Much appreciated! Tell Mila thank you!

Horrible upgrade.

I rarely use Mila’s tools, so I only need the basic free part of the app. I just installed the latest update for Miller’s tools and now I cannot use it at. It keeps trying to sell me anywhere from a monthly subscription to a yearly subscription. Every time I try to do a Conversion it flips me or to a page to join Miller’s tools pro. I cannot use my free version. This is a very deceptive sales trick. Now my free app is completely useless because every time I go to look something up it goes to the subscription screen. I am very disappointed in what they’ve done to this app. Used to be ab5 star app, not any more.

Response from developer

Thank you for your feedback, VBonanza. I appreciate you taking the time to share your experience. Of the 29 categories in Mila's Tools, 23 are completely free and always will be — including Length, Weight, Volume, Temperature, Speed, Pressure, and many more. Six categories (Cooking, Data Transfer Speed, Frequency, Ring Size, Shoe Size, and Slope) require a PRO license and have since they were first introduced. That said, your feedback tells me the distinction between free and PRO categories wasn't clear enough. I'll be shipping an update that adds to the existing lock icon a visible "PRO" label to those categories and a clear notification when you open one, so there's no confusion about what's included for free. If you're having trouble with any of the 23 free categories, please reach out to me at scott@scottdesapio.com so I can help you directly. I read every email myself. I'd like to make sure the app is working well for you.
