### 3/5 — Fix pdf file!!

*2026-07-15*

Awesome app! I use it all the time for fabrication. On the cut optimizer if you make the file to big you can not load the pdf file. Also on the cut optimizer you have to singly hit the minus/plus button to change quantity. This is aggravating with you have hundreds of pieces. You should be able to type the amount in. This is the only complaint I have found but needs fixed!

**Developer response:** Thanks for the comments - Please email me at WinogradApps@gmail.com if you find any other issues - these are fixed for the next update which is coming out very soon! Best, Evan

### 5/5 — Must-Have App for DIY Projects

*2026-04-20*

This app has become one of my go-to tools for DIY projects. What started as a simple feet and inches calculator turned out to be a whole toolbox packed into one app. I keep finding more useful features every time I use it, from angle calculations to rafter sizing to staircase layout help. It is incredibly practical, easy to use, and clearly built with real-world projects in mind. For any DIYer, carpenter, or weekend builder, this app is an absolute gem.

**Developer response:** Thanks so much for the review! Glad you’re continuing to find useful features in the app, and if you ever have any questions or ideas for additional features please don’t hesitate to reach out at WinogradApps@gmail.com

### 5/5 — Easy to Use

*2026-02-12*

Best app for measurements and I love how it gives you both results. There is so much more to this app if you go into the tools. It provides everything I am looking for. As a matter of fact, I didn’t realize that you could include price per board foot until just today. It’s fantastic.

**Developer response:** Thanks for the review! I'm adding cost and custom units to the unit converter tool in the next release (version 8.4). This will allow you to say, for example, 350 square feet = 1 gallon of paint = $45. I'm also adding fill materials (e.g. asphalt, sand, gravel) with cost to the concrete tool. Feel free to email me at WinogradApps@gmail.com with any other requests!

### 5/5 — Easy to Use

*2026-01-13, version 8.2.0*

Best app for measurements and I love how it gives you both results. I would say that if there was a way to calculate cost somehow, that would be the cherry on top, but there is so much more to this app if you go into the tools. It provides everything I am looking for.

### 5/5 — Not just a conversation calculator.

*2025-12-12, version 8.0.0*

This app has so many different tools in it it’s amazing that’s it’s free. I’m about to build a barrel sauna out of cedar fence pickets and this helped me calculate the best OD for my project. Just one of the many incredible tools this app has. I’m going to buy a lifetime subscription to show my appreciation to the creator.

### 5/5 — Perfectly up to date!

*2025-12-06, version 8.0.0*

This app is excellent for daily use and is consistently updated. Thank you to the Feet and Inches Calculator team for their continued support.

### 5/5 — Excellent app

*2025-11-07, version 7.18.2*

I don’t usually review apps, but I had to for this one. As a framing carpenter, this app couldn’t be more useful. Great app!

### 5/5 — This app is a public service. Amazong

*2025-10-31, version 7.18.2*

Does everything i need it to it to for home building.   Love that you can send stair stringers to PDF.

### 4/5 — Fait de mauvais calculs

*2025-08-14, version 7.16.9*

J’ai fait un calcul bien basique,
90’ + 5’ 10 ‘’. 
Sa me donne 5 pieds 8 pouces…
Je ne comprends pas. 
Faites attention quand vous calculez avec. 
Je vais tenter de le réinstaller pour voir si sa arrange le problème. C’est la première fois que je rencontre un bug pareil avec l’aplis et sa fait un bout que je m’en sert.

### 5/5 — Great app

*2025-07-31, version 7.16.9*

This is the best app I’ve found for imperial arithmetic that doesn’t force you to spend money for it
