I took me time to understand on how to use it. But very good measuring stuff equipment. -- MatRamon, 2024-09-12 ### ***** "Excellent tool!" Thank you very much! -- Sevikha, 2024-01-10 ### ****- "Very nice app" Could be better if there is another way to increase/decrease values other than touch screen as I always wast my time trying to got the correct measure by touch screen -- LE2D3R, 2022-01-21 ### ***** "Excellent!!" I love this app!! -- Hartig2626, 2021-01-22 ### *---- "Can you measure with your camera?" Wondering... -- Mmsjdenfeufskrhdtnocf, 2019-09-11 ### *---- "Worst Ever Waste of Money" Horrible app. The title says it all. Avoid -- raygood32326, 2019-01-14 ### ****- "Millimeter Pro" Good app !! Great for measuring small items. Very handy for screws , nuts and bolts . -- RTC333, 2017-04-22 ### *---- "Not accurate on iPad" This app is accurate on the iPhone but not the iPad. -- charleslon, 2017-03-15 ### ***-- "Perhaps I need simplicity" but I do love I found u ~ however, I find I do not use u. I am a Jeweler and Potter that needs mm and inch measurements visually as well (represented as a ruler would) The grid is more than 2 mms, so visually it is easier to use my good ole completely off brass calipers. Aggghhhhh!!!! The concentric measurement could come in handy with pottery. Show me true mms, and I would be happy. -- mldrocks, 2017-03-01 ### *---- "Not working on iPad Pro" The measurements are too big, when using iPad Pro. -- teknolojay, 2016-04-08 ### ***** "Great tool" I have found this to be very useful on both my iPhone5 and iPad pro. I haven't had any problems. -- Denverbella, 2016-03-21 ### **--- "Not on iPad Pro" Can't get it to scale properly, scale is way off (30% high), perhaps right for smaller iPad, totally useless for me! Needs a calibration option... -- immortal8, 2016-02-22 ### ***** "Thank You!" I have been waiting for years for an app developer to create a diameter ruler for ME. 😊 Thank you very much! I am an avid brooch collector and I get tired of having to estimate the size of a brooch using a linear or t-square ruler when a diameter ruler would oftentimes give me a better visual. If you wanted to make my year, make an option where I could stretch one side of my circle to create an oval/rectangular shape to better visualize the size of jewelry that has more oval/rectangular dimensions than circular. Great work! Thanks again! -- SoapingFanatic, 2015-03-31 ### ****- "Works great on my iPhone 6 Plus" After the latest update, it all works fine on my iPhone 6 Plus. I've verified it with a ruler and engineering lined paper. -- SyrinxSean, 2014-11-14 ### *---- "Needs to be updated!!!" Worked great until I upgraded to the iPhone 6 where the different screen size causes inaccurate measurements! This app literally has one job and it doesn't do it correctly anymore. -- MattCarl, 2014-10-26 ### **--- "Only good for calculating simple area." This app is only good for calculating simple square areas or circular areas. Does not help with angle calculations. -- Orc trader, 2014-07-22 ### *---- "Absolute waste of time" This is a complete waste of time & money... -- MhollidayGCR, 2014-03-28 ### ****- "Very handy for measuring small parts" I build bikes and deal with several hundred small parts, mostly in mm, this is great for a quick check on sizes and angles. I was just looking for graph paper and found this app which is much better. One suggestion: could you reduce the precision to 0.1mm and .01 inches? The extra digits make it harder to read and if I need more accuracy, I'd need to use calipers anyway. Thanks. -- notjustus_aw, 2014-03-09 ### ***** "Useful app" Used this app to show my girlfriend that a 1 carat diamond (6.1mm X 6mm) is bigger than she thought. Probably saved me a considerable amount of money. Simple, fast and effective app to make you phone a useful tool. 5 stars. -- Franky4toes, 2014-01-28 ### ***** "Handy reference tool" Great for measuring on the fly. Easy and intuitive to use. Would recommend. -- Deeohgee81, 2013-04-15 [View all Millimeter Pro reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Millimeter Pro Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Switzerland | Utilities | #23 | | Top Paid | Algeria | Utilities | #100 | | Top Paid | Colombia | Utilities | #257 | | Top Paid | Russia | Utilities | #271 | | Top Paid | Switzerland | Overall | #272 | | Top Paid | Pakistan | Utilities | #274 | | Top Paid | United States | Utilities | #277 | | Top Paid | Azerbaijan | Utilities | #305 | | Top Paid | Ukraine | Utilities | #326 | | Top Paid | Finland | Utilities | #328 | | Top Paid | Dominican Republic | Utilities | #330 | | Top Paid | Austria | Utilities | #365 | | Top Paid | Nigeria | Utilities | #369 | | Top Paid | Egypt | Utilities | #375 | | Top Paid | Israel | Utilities | #377 | | Top Paid | Philippines | Utilities | #379 | | Top Paid | Greece | Utilities | #388 | | Top Paid | Kuwait | Utilities | #397 | | Top Paid | Italy | Utilities | #401 | | Top Paid | Vietnam | Utilities | #427 | | Top Paid | Brazil | Utilities | #434 | | Top Paid | India | Utilities | #473 | | Top Paid | Indonesia | Utilities | #488 | ## Millimeter Pro Discovered Keywords -
