iPhone
Interviews is the daily workout for anyone preparing for a mobile developer technical interview. Five questions a day, two minutes, and a path that grows with you.
FOUR TRACKS, EACH ON ITS OWN
Swift, UIKit, Kotlin and Flutter. Turn on one or all of them: each has its own topics, in the order it makes sense to study them. You start from the fundamentals of
the language, never halfway through.
THE DAILY QUIZ
Five questions tuned to your level, drawn only from the topics you've already unlocked. Answer, read the explanation, keep your streak alive.
XP AND RANKS
From Junior I all the way to Staff. Every correct answer is worth 10, 20 or 30 XP depending on difficulty, and your rank decides how hard the daily questions get.
REVIEW WITH REAL ANSWERS
Short lessons with annotated code and, above all, the answer to actually give out loud to the person interviewing you.
CORRECTIONS THAT EXPLAIN
When you get one wrong you don't just see the right answer: you read why yours was wrong. Your mistakes stay set aside until you fix them.
SMART REMINDERS
One notification at the time you choose, only on days you haven't done the quiz yet. Never one more.
OFFLINE, NO ACCOUNT
Interviews works on the subway as well as on the couch. No sign-up, no ads, no tracking: your progress stays on your iPhone.
FREE, AND INTERVIEWS PRO
The Junior stage of all four tracks is free, lessons and quizzes included, and stays free. Interviews Pro opens the Mid and Senior topics too, and lets the daily quiz
follow your rank.
Interviews Pro is an auto-renewing subscription: 1.99 EUR per month, or the equivalent in your currency. It renews automatically unless cancelled at least 24 hours
before the end of the current period. Manage or cancel it in Settings on your iPhone.
Available in English and Italian.

LESSONS IN PLAIN WORDS
All 40 topics, from scratch. Nothing taken for granted: every term is explained
the first time it shows up. And when you get a question wrong you no longer just
read the right answer — you read why the one you picked looked right, and why it
doesn't hold.
YOUR STREAK, IN FULL
Tap the flame to see where you stand: the calendar of the last five weeks, your
best streak, and the XP you earned day by day.
SIX LANGUAGES, LIGHT AND DARK
English, Italian, Spanish, French, German and Portuguese, in the theme you
prefer. Lessons and questions are written by hand in English and Italian.
INTERVIEWS PRO
The Junior stage of all four tracks stays free. Pro opens the Mid and Senior
topics too, and lets the daily quiz follow your rank: 1.99 EUR a month, or the
equivalent in your currency, cancel any time.
Also: the real mark of each language on its track, a new icon, and an opening
screen.
