Just forget this app and do the calculations ### 3/5 — Eliminate don’t want to end on the bottom of the screen need to eliminate *2020-10-18* Eliminate ads, Don’t wanted the Ads on the bottom of the screen it’s annoying to do my work or planning things of it. I think it didn’t have it in my older iPhone and iPad too. ### 1/5 — Not great *2020-03-05, version 2.0.0* Hi.. not great.. won’t do 1.22.5 scale and won’t do imperial length to metric in scale ### 4/5 — Nice app *2012-05-21* Model train scales go down to 1/220 for Z scale. Any chance to update the app for smaller scales? Thank you ### 5/5 — great app *2012-01-14* even better it's free! ### 4/5 — Exactly what I was hoping to find. *2011-04-26, version 1.0* This came in very handy and is easy to use. Would be 5 stars but it could do with higher scales to choose. ## Frequently asked questions about iScaleModel ### What is iScaleModel used for? iScaleModel is used to quickly calculate scale model dimensions by converting between metric and imperial units.
