Surely it wouldn’t have been difficult to add 1:6, 1:12, 1:144 and maybe 1:16. There was no indication in the description before I downloaded it that it would be tedious to swap back and forth between the various dollhouse scales I work in. ### 3/5 — Take it a bit farther *2018-08-24, version 6.0.5* Be nice if it allowed you to plug in an advertised scale distance and generated an actual real-world size. ### 2/5 — Newbie *2018-08-03, version 6.0.5* Can’t get it to work for custom scales eg 1:35 ### 3/5 — Mr *2018-04-13, version 6.0.5* I preferred the previous layout. The new one seem really clutter and it is a bit slow to be honest. ### 3/5 — Seems unfinished *2016-12-30, version 5.0.0* The calculator works but there is more to the app that doesn't work. Products & videos for example. ### 2/5 — Needs to be Updated *2015-12-04, version 4.2* I really like this app. It makes conversions at scale very easy. The only real issue I have is that the units, i.e. cm, mm, in. Etc., can mot be changed. Please update to fix this bug. ### 4/5 — Helpful but needs more. *2015-11-01, version 4.2* Needs more features. Want to convert HO to N scale. Can only concert real life measurements to whichever scale you choose. ### 3/5 — It will not let me move from cm to inch it stuck *2015-10-20, version 4.2* I can not move it from mm to inches ### 1/5 — Unable to change unit *2015-09-27, version 4.2* From a long time now, i have been unable to change the unit after setting the scale. I hope the repair this glitch ASAP! ### 4/5 — Good app *2014-01-18, version 4.2* It's pretty much a giant advertisement for their shop but the tool is very useful, saves me a lot of time. ### 3/5 — No OO Gauge! *2013-09-28, version 4.2* Therefore quite useless for me! ### 1/5 — Not worth it *2012-10-28, version 2.8* Where's the Z scale? And it says regroup all scale, what a lie. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can’t change scales *2023-06-20, version 6.0.5* Every time I try to change to any scale other than the default, it crashese ### 1/5 — Great Idea *2019-05-05, version 6.0.5* I was really looking forward to using this App. However, I could not change the scale, it defaulted to G scale and no other scale could be selected. ### 1/5 — What happened update 6.0.5 *2018-04-06, version 6.0.5* Certainly not an app I would be proud to say I made. From a fine visual layout to something a first year student could design. Hope it still calculates properly. ### 1/5 — Was a good App *2017-05-07, version 5.0.0* This was a very good App you have taken the best parts away, you can no longer send it to you email, you can no longer pick a photo from your pictures, please fix these issues ### 1/5 — Limited Functionality on iOS 9.3.1 *2016-05-10, version 4.2.2* The initial used occurred on iOS 9.3.1 There are very few of the features/menus that actually respond. Only the "Menu" and "Scale" choices reveal new content on the screen. The other choices do not work. ### 1/5 — What does it do? *2016-04-18, version 4.2.2* I'm not actually sure what it does apart from convert sizes for you but if your building something from scratch I'd assume you'd be on top of that anyway. There are pictures of products on some of the scales you but you can't click on them or anything. Bit of a waste of time really imho. ### 1/5 — Disappointing *2016-01-22, version 4.2.2* A pretty useful app, but really not much more than a showcase for Woodland Scenics products; that would be OK if the app still worked after the recent iOS 9 update--which it doesn't! ### 1/5 — Horrible *2016-01-18, version 4.2* Useless app can't change from mm to any other type of measurement. ### 1/5 — Broken *2015-12-17, version 4.2* The scale would not let me change from mm. I would not bother even attempting to use this until it is fixed. If fixed then I would use it. ### 1/5 — Disappointed *2015-12-10, version 4.2* Can't change anything in the drop down boxes. Can't change to HO scale, won't let me add to different categories I created. ## Most praised reviews (10 highest-rated) ### 5/5 — Simple and effective *2023-11-03, version 6.0.5* I’m not sure what others expect of this app? But it does exactly what it’s supposed to do. It’s so easy to enter the scale you are working in, enter a real world measurement and it gives you the scale equivalent. That’s all it claims to do, and it does it very well. I love it! And use it often when modeling my railroad. Saves me a ton of math! ### 5/5 — Works *2020-10-28, version 6.0.5* It does exactly what it says should do, calculate in hobbie scale and it’s free with a nice interface. it have popular preset scales ready plus it lets you enter your own custom scale if needed. ### 5/5 — Great Tool for Serious Miniaturists *2019-02-17, version 6.0.5* I make scale dollhouse miniatures in 3 different scales and being a bit “mathematically challenged”, sometimes got confused when trying to calculate the dimensions an object had to be to be exactly ‘in scale’. The smaller the item, the harder this became. Your app has been a lifesaver for me ever since my first forays into 144th scale (aka micro-mini, 1:144, 1”=12’). The best part is that one can customize the fields to convert between metric and imperial measurements, use custom scales as well as standardized hobby scales and even determine the scale of something with a few basic measurements using a reverse engineering approach. It could do with a bit of work on the visual aspects of the page, ;-) but the main thing is that IT WORKS!! and ITS FREE!!. ‘nitfiend’ in 🇨🇦 ### 5/5 — Very useful App! *2018-04-13, version 6.0.5* Just calculates between real and scale sizes in a wide variety of different types of measurement. Hardly a complicated app but extremely useful to any modeller and none of the usual in your face ads! ### 5/5 — Amazing *2017-12-13, version 5.0.0* great jobs.. ### 5/5 — Big help for a G scaler *2014-01-17, version 4.2* This app helps convert known real size measurements into scale measurements. I like that I can also create my own scale (since G scale has multiple scales). ### 5/5 — Modeler *2013-12-29, version 4.2* Great product ### 5/5 — Very useful *2013-08-12, version 3.2* My go to app for scale conversations. ### 5/5 — Simple, works a treat and it's free. What's not to like? *2012-09-09, version 2.8* Great little tool for scale model builders, especially to build correct dioramas. ### 5/5 — Works a treat! 😍 *2012-06-09, version 2.6* Have been scaling manually for years having so much furniture & no perspective so to find 'an app for that' is awesome. Tried several that were very complicated but this is simple and easy to use. Thank you x --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
