### 3/5 — WAS a good App. Not anymore 😵‍💫

*2026-08-17, version 2.8.29*

This used to be a great app. Unfortunately, it has degenerated into SUBSCRIBE every mouse click/finger tap app. Sooooo annoying that Mila is going to the dump, dump, dump, right after this review.

### 5/5 — Every type of unit convinces you will ever need!

*2026-08-14, version 2.8.29*

I can safely say that I would be lost without Mila’s tools on my phone the reference tools are accurate and simple to understand!

### 5/5 — Gr8

*2026-07-15, version 2.8.28*

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.

### 4/5 — Great app for converting

*2026-07-07, version 2.8.28*

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

### 5/5 — Essential App

*2026-06-22, version 2.8.27*

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!

### 1/5 — Horrible upgrade.

*2026-05-25, version 2.8.21*

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.

### 5/5 — Most useful app

*2026-05-25, version 2.8.21*

Whoever created this is a genius. So user friendly and intuitive.

### 5/5 — The only converter you’ll ever need.

*2026-05-24, version 2.8.21*

This is my goto unit converter, I’ve used it for a long time. It resides on my Home Screen. It is so simple to use. Thanks for making this app.

### 5/5 — Magic App

*2026-05-17, version 2.8.2*

Been using this app for more than 5 years, has been an absolute Godsend when needing a quick conversion on the go

Highly recommend

### 5/5 — Great app

*2026-05-03, version 2.8.0*

I use this app alll the time it’s fantastic keep up the great work and have a great day

## Version history (last 5 releases)

### 2.8.29 — 2026-08-10

* Slider haptics: dragging the Blood Sugar slider now gives tactile ticks, with a stronger pulse when crossing Low, Normal, Pre-diabetic, or Diabetic boundaries.

### 2.8.28 — 2026-06-23

• Added UK letter ring sizes (A–Z with half sizes) alongside US, EU, and Swiss standards

### 2.8.27 — 2026-06-13

### 2.8.26 — 2026-06-12

• Glucose log: Track your blood sugar readings over time — view history, add entries manually or from converted values, edit past readings, and attach notes.
