Verdict
The clearest difference is ads: Gemini Markets at none against CEX.IO's shown. Gemini Markets also leads on rating (4.8 vs 4.4) and update cadence (every 3 days vs weekly). CEX.IO's advantage is review sentiment (74% vs 51%). 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. Neither carries in-app purchases, so what you see is what you pay.
Gemini Markets holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Gemini Markets has 110K ratings behind it against 13K, so its average is the more settled of the two. Written reviews complicate that: 74% of CEX.IO's written reviews are positive against 51% of Gemini Markets's, so the app with the better star average is not the one people write more warmly about.
CEX.IO ships an update weekly, Gemini Markets every 3 days. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
