Unfortunately I'm not a big fan of the Apple phone, I prefer the Samsung, you can download Coingecko or CoinMarketcap, can you upload the application in the Appstore?
because I usually use these 2 applications.
I agree with you, many users have an Android system, and Coingecko or CoinMarketcap is enough to work with cryptocurrency, but as a rule, CoinMarketcap is the standard one. If there are no such applications, there should be analogues in the appstore, we are waiting for the opinion of Apple supporters, sometimes I really want to switch to their products, and this question will also arise in my mind.
