About EM Field Guide
EM Field Guide is a phone app for engineering managers that helps them rehearse a hard conversation before they have it. It is made by Polanyi Works, a software studio in Singapore and a brand of E2C2 Pte Ltd.

EM Field Guide is for iPhone and Android.
Status
As of 21 October 2026, EM Field Guide is not yet in the App Store or Google Play.
What it costs
It is free to start. You get a free case every week, with a limited number of rehearsals. Pro adds every case and more practice. Plans are Monthly, Yearly or Lifetime, and the price is shown in the app before you buy.
What a case contains
Each case covers why the conversation is hard, what matters, and words you can use. Every case shows how the same situation shifts across cultures. Asia is covered first, with written notes. You can read a free part of some cases in the case guides.
How cases are written and sourced
The case itself is written by a person. The case guides list the published sources each case draws on.
How AI is used, and its limits
The characters you rehearse with are made up and written by AI. Their replies can be wrong or unrealistic. The character's job is to be a plausible colleague for ten minutes, so you can try your opening before it counts.
What it is not
EM Field Guide is practice. It is not therapy, and it is not legal, HR or medical advice. If a situation involves dismissal, a performance plan, discrimination, safety or health, talk to your HR team or a qualified professional.
Privacy
You can browse and read without an account. There are no ads, and no tracking across other apps or sites. You can delete your account, and everything with it, in Settings. The privacy policy names each provider that handles what you type.
