Thought I would share this app I found on the Apple Store called Blockfolio.
I have numerous coins and spreadsheets but as you would know that can get quite time consuming to update.
I have found this very useful for a place to store my portfolio and I have not entered any private details so it seems secure.
Please let me know otherwise.
I did do a checkup on scam adviser and it got a low rating however I have no concerns as there are no coin related security details on my phone.
Not sure on its privacy or otherwise however I am using it and it has been very useful for quick market reviews, alerts and updates and in real time.
Feel free to check it our if it is of interest and it was also FREE.
