Disclaimer Crypto assets are not legal tender and may be used to settle a payment only if the person receiving the payment agrees. The price of crypto assets may fluctuate due to changes in the balance of supply and demand and other factors, which may result in losses. Fees and other charges may apply to crypto asset and related transactions. For details on fees and other charges, see “Fees and Taxes” on our website. To engage in over-the-counter crypto asset derivative transactions, you must provide a margin deposit. For details on the required margin deposit, its calculation method, the applicable margin rate, and other margin-related information, see “What is bitFlyer Crypto CFD?” on our website. Over-the-counter crypto asset derivative transactions let you trade amounts exceeding your margin deposit with a small amount of funds. However, rapid price fluctuations of crypto assets and other factors may cause losses exceeding your margin deposit within a short period. In over-the-counter crypto asset derivative transactions, factors such as sudden price movements or the execution of a loss-cut may result in a trade being executed at a price or under conditions different from those you anticipated at the time of your order, or may result in a trade not being executed at all. Before trading, be sure to thoroughly review our pre-contract disclosure documents and related materials.

Verdict
The clearest difference is review sentiment: AITFX at 94% against bitFlyer's 33%. AITFX also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 17.0). bitFlyer's advantage is rating (4.3 vs 4.0) and ratings volume (282 vs 44). On price, update cadence, ads and in-app purchases 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.
bitFlyer holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: bitFlyer has 282 ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 33% of bitFlyer's written reviews are positive against 94% of AITFX's, so the app with the better star average is not the one people write more warmly about.
bitFlyer ships an update every 9 days, AITFX fortnightly. Both last shipped on October 24, 2026.
