Why This Comparison Matters Right Now

1. Search surge: Google Trends shows a +320 % spike in “iPhone Duo vs foldable” searches between Mar 1 – Apr 15 2026.
2. Price parity: Duo launches at $1,099 (128 GB); Samsung Z Fold 5 at $1,149, Xiaomi Mi Fold 4 at $999, Honor Magic V at $1,079. The premium gap has essentially vanished.
3. Supply chain stability: Apple’s vertical integration has eliminated the component shortages that plagued Android foldables in 2023‑24, ensuring global availability.
4. Regulatory edge: The EU’s “Right‑to‑Repair” law (effective Jul 2026) forces manufacturers to publish repair manuals and spare‑part pricing. Apple is already compliant, giving Duo a lower total‑cost‑of‑ownership outlook.

Practical Tools

1. Google Sheets Price‑Tracking Workbook

1. Open the price‑tracker.xlsx file in Google Sheets.
2. Insert your Keepa API key in cell B2.
3. The sheet automatically pulls daily Amazon price data for the four devices and plots a line chart.

# Example: Adding your API key
B2 = "YOUR_KEEPA_API_KEY"

2. Python Sentiment‑Analysis Script

#!/usr/bin/env python3
import os, json, csv
import requests
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer

# === CONFIG ===
YOUTUBE_API = os.getenv("YT_API")
REDDIT_API  = os.getenv("REDDIT_CLIENT_ID")
REDDIT_SECRET = os.getenv("REDDIT_SECRET")
QUERY = "iPhone Duo review"

def fetch_youtube_comments():
    url = f"https://www.googleapis.com/youtube/v3/search?part=snippet&q={QUERY}&type=video&maxResults=5&key={YOUTUBE_API}"
    vids = requests.get(url).json()["items"]
    comments = []
    for v in vids:
        vid_id = v["id"]["videoId"]
        com_url = f"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&videoId={vid_id}&maxResults=20&key={YOUTUBE_API}"
        for c in requests.get(com_url).json().get("items", []):
            comments.append(c["snippet"]["topLevelComment"]["snippet"]["textDisplay"])
    return comments

def fetch_reddit_posts():
    headers = {"User-Agent": "duo‑compare‑bot/0.1"}
    url = f"https://www.reddit.com/search.json?q={QUERY}&limit=20"
    resp = requests.get(url, headers=headers).json()
    return [p["data"]["title"] + " " + p["data"]["selftext"] for p in resp["data"]["children"]]

def analyse(texts):
    analyzer = SentimentIntensityAnalyzer()
    rows = []
    for t in texts:
        score = analyzer.polarity_scores(t)
        rows.append([t[:80] + "...", score["compound"]])
    return rows

if __name__ == "__main__":
    data = fetch_youtube_comments() + fetch_reddit_posts()
    results = analyse(data)
    with open("duo_sentiment.csv", "w", newline="", encoding="utf-8") as f:
        writer = csv.writer(f)
        writer.writerow(["Excerpt", "CompoundScore"])
        writer.writerows(results)
    print("✅ Sentiment CSV generated: duo_sentiment.csv")

Run the script (python3 duo_sentiment.py) after setting the three environment variables. The output CSV can be opened in Excel or Google Sheets for quick visualisation.

Resale‑Optimization Tips

1. Factory‑reset & clean – wipe the device, reinstall iOS, and run the “Erase All Content” routine.
2. Document condition – take high‑resolution photos of both screens, back, and ports.
3. Bundle accessories – include MagSafe charger, dual‑screen case, and original packaging to command a 10‑15 % price premium.
4. List on multiple platforms – eBay, Swappa, and local Facebook Marketplace simultaneously; price‑track with the Google Sheet to spot the optimal window (historically 3‑4 months after a new model launch).
