Not much help for anyone who wants to just browse and learn some new things. Perhaps the title and description could be worded better to outline this to prevent users from downloading it and deleted? **Developer response:** Thank you for your feedback. While you would need to look up a term to get started, you might be interested in the "Mentioned in" box that appears on the bottom of dictionary pages, as it gives you a list of other engineering pages to potentially browse. ### 4/5 — Only for confirming what you already know? *2025-01-20* I’m not sure if I’m missing something, but this isn’t a dictionary, just a search box reading entries from unknown third party databases. It may or may not give you some info about a search term you already know, but you can’t use it like a dictionary, to browse or learn, or find related items other than the very few tossed into the databases. **Developer response:** Yes, our Engineering app is a searchable database of terms. Each entry has its dictionary source listed under it, next to the blue "CITE" link. ### 4/5 — Informative *2022-04-15* Informative but lacks drawings. Need more draining please. Also opening in the browser than within the app. Why does it do this? ### 5/5 — Add some languages *2020-09-05* I really appreciate the work you guys have done to build this app. I would like to know if you guys can help people who speak French and Spanish to have access to this app. It’s fantastic and I really appreciate the job. Please help the French and Spanish community to use this app. ### 5/5 — Gucci *2020-08-13* Maine this app is dope! ### 1/5 — Horrible *2018-11-23* Very common electrical engineering terms missing, hire an editor! **Developer response:** We're sorry to hear that. Please email support[at]tfd[dot]com with some examples of words that you have not been able to find in the app, so we can investigate. ### 5/5 — BK *2018-03-05* Incredibly handy for report writing. ### 1/5 — Ripoff *2017-08-08* Piece of junk doesn't work stole my money😡 ### 4/5 — Nice program *2017-06-23* It's amazing ### 5/5 — Baghdad *2017-04-22* Thanks ## Frequently asked questions about Engineering Dictionary. ### What does the Engineering Dictionary app do?
