Verdict
The clearest difference is ads: Next Up at none against i's shown. Next Up also leads on review sentiment (76% vs 43%) and ratings volume (2.8K vs 1). i's advantage is rating (5.0 vs 4.7) and update cadence (every 9 days vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Next Up sells 2 in-app purchases, starting at $3.99 per month and i sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
i holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Next Up has 2.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 76% of Next Up's written reviews are positive against 43% of i's, so the app with the better star average is not the one people write more warmly about.
Next Up ships an update every 5 weeks, i every 9 days. The most recent releases landed on September 24, 2026 and August 20, 2026 respectively.
