AI Interview Coach — Voice-Based AI Interview Practice iOS App (SwiftUI + Gemini AI)

AI Interview Coach is a complete, ready-to-publish native iOS app where users practice job interviews by talking to an AI interviewer. The AI asks questions out loud, the user answers by voice, and after 10 questions the AI generates a full scored report with strengths, weaknesses and improvement tips. Built 100% in SwiftUI with Google Gemini AI — no backend server required.

AI speaks → User answers by voice → Live transcript → AI scores the interview
A real spoken conversation loop, not a chat app!

AI Usage Disclosure

This item uses AI as a core feature. AI Interview Coach integrates the Google Gemini API to generate interview questions, produce short interviewer reactions, and evaluate the user’s answers into a scored result. The app sends the interview category and the user’s transcribed answers to the Google Gemini API over HTTPS and displays the AI-generated response in the app.

AI service used: Google Gemini API (model gemini-2.5-flash)
What is sent to the AI: the selected interview category and the user’s transcribed text answers
What is NOT sent: no audio recordings are uploaded — speech is transcribed on-device by Apple’s Speech framework; only text is sent
Buyer requirement: buyers must supply their own free Google Gemini API key (setup takes ~2 minutes, no credit card). Use is subject to Google’s API terms.

✨ Key Features

AI Scoring & Result Report — animated 0–100 score ring, A–D grade, strengths, areas to improve, actionable tips, overall feedback and full answer review — with confetti celebration for high scores
Interview History — every interview saved locally with filters by category, sorting by date/score, swipe-to-delete, and summary stats (average score, best score, most practiced)
Personal Onboarding — asks the user’s name only on first launch, greets them by name forever after
100% Local Data — no login, no account, no server; results stored on device (UserDefaults + JSON)

Why Buyers Love It

No backend needed — just paste one free Gemini API key and run. Setup takes 2 minutes.
No third-party libraries — pure Apple frameworks (SwiftUI, Speech, AVFoundation) + one REST API. Nothing to install, nothing to break.
Clean MVVM architecture — organized folders (Models / Views / ViewModels / Services / Utilities), MARK comments in every file, async/await networking.
Easy to rebrand — all colors in one Constants file; add new interview categories with a single array entry (Gemini generates questions for any job role automatically).
Trending niche — AI + interview preparation + voice apps are among the hottest app categories right now.

⚠️ Important Notes (please read before purchase)

A free Google Gemini API key is required (takes 2 minutes, no credit card). Interviews need an internet connection; history works offline.
Voice features must be tested on a real iPhone — the iOS Simulator’s microphone is unreliable (Apple limitation, not an app bug).
This is an iOS app (iPhone) — Android is not included.
For App Store publishing you need an Apple Developer account. For a large-scale public release we recommend moving the API key behind your own proxy server (guide note included in docs).
App name, colors and branding shown in previews are fully customizable.
