iPhone Alley Showdown: Apple’s Siri vs. True Knowledge’s Evi

Though it’s only been out for a few days, Evi has already risen to the top of the App Store charts but for some reason only has one and a half stars. Puzzling for an application that promises to function in ways that somewhat resemble Apple’s creation currently in beta called Siri. Today we’re going to take the two technologies through a variety of tests to see which is faster, more reliable, has a better interface and which of the two is ultimately the friendliest!

Evi, a one-eyed virtual assistant whose creators promise that she can do everything that Siri can, indirectly of course, and more. According to the application’s description, she can:

“Say hello to Evi.

Evi is the revolutionary artificial intelligence here to help with all of your everyday information needs.

Unlike a search engine, which simply looks for matching words and shows you a list of websites, Evi understands what you want to know and gives back exactly what you’re after.

Need to know where the nearest bank is? Not a problem. Going out for dinner but can’t decide where? She can help with that too. The more you ask, the more she will learn, and thus she is improving all the time.

Life is simpler with Evi.”

Slow, non-dependable, buggy – all things that have been used to describe Evi in the past few days that she’s been existent. We agree to the fullest extent possible, but she’s also got a few positives that make her quite the ideal competition for Apple’s own Siri.


We tried asking various questions to Evi, which the answers to were either here or there: she either responded with an answer, or she didn’t respond at all (server error message). She seems to know a whole lot more information than Siri does, though. While Siri seemingly only knows how to direct you to places, among a few other capabilities, Evi can tell you a whole lot more.

For example, we asked how many days there were until Christmas to both Evi and Siri, and both returned with answers. Then we asked both how they pronounced their names. Still, they both answered. Then we asked Evi “how old is Steve Jobs” (no disrespect in anyway), and she answered with the exact date of his decease, the place and how old he was exactly; she also answered out loud.

Asking Siri, we were returned with a box with one of her usual text boxes, meaning no audio response, stating the date of his passing. Even though that’s not the best of examples, it still proves one thing: Evi can be more resourceful as Siri at some times.


While Evi’s application interface sports a much cooler look to it over that of Siri’s, the latter maintains the usual Apple vibe and was intentionally designed to be a quick thing that you usually wouldn’t spend much time observing.

That said, it’s appreciated that Evi boasts a much nicer, cooler-on-the-eyes aesthetic but needed for an application as such. What does help, though, is that True Knowledge has included a ton of other features that easily appeal over Siri; they’ve put in a button to indicate that you can input by both text and voice, a beginning tutorial that sort of explains all of the features, a feedback sender that they’ll hopefully capitalize on, lovable animations and more. Additionally, when you’re inputting your questions, Evi will recognize some words and cross reference them with other questions asked by other users to offer you multiple, non-obtrusive suggestions.


While Evi may look superior and may have a better, cleaner and easier navigable interface, she lacks greatly on a few things that Siri does not. For example, a simple question that does not need the following, sometimes results in a message that Evi is trying to reach her serves or some other annoying message of the like. It also seems that whenever she doesn’t know the answer to a question, she throws a server error at you, which may not be the case, but it happens ever too frequently. There was also the unique case when I couldn’t input a question through voice because Evi “couldn’t reach her vocal servers”.

I’m not sure if Evi is simply incapable of answering some questions or if the sudden influx of users has overloaded the initial expectations of her servers, which the latter is what I’m hoping, but she does seem to be a bit behind in the area of actual material that she provides you with due to her lag and constant server issues. However, that doesn’t take away from her overall potential, which can be developed further to an extent that will easily knock Siri out of the game, considering the form that Siri is currently in.

We’d still recommend purchasing Evi right now, for when she does return with an answer, she returns with a reliable, trustworthy answer instead of directing you to Safari to search it up. Until she’s updated to handle questions better, she’s still a worthy alternative to Siri for older generations of the iPhone.
