Good app and well integrated

It is very fast, integrated into the top bar at all times. Helps a lot being on the phone. Programmers have trully done a good job.
Could use a history - or frequently used - since the address and names are typically typed over and over.

Genuinely Useful, but Speech & Pronunciation Flawed

Great for people who only occasionally use the NATO phonetic alphabet. Useful for communicating serial numbers, model numbers, and other information required by technical support for products and services, just to cite one use.

The speech-synthesized voice has little value. It speaks far too slowly. The pronunciation is not correct. For example, in th NATO alphabet, “Lima” is pronounced “LEE-MAH.” This application pronounces it “LIE-MAH.” “Oscar” should be pronounced “OSS-CAH.” This program pronounces it “AW-SKER.” Instead of pronouncing “Victor” as “VIK-TAH,” per the NATO pronunciation, it pronounces it “VIK-TOR.” There are other examples, but suffice it to say that it’s just wrong and misleading.

Small, fast and exactly what you need when upgrading your flights or asking for status

Great little app, nothing to crazy, but super helpful if you have to work thru automated systems. Get info over the phone on case files and other things.
