It's good to have choices, personally I'm happy with the Blockfolio app, though I feel it takes more time than it should to update my portfolio with the latest staking/mining rewards and trades from unsupported exchanges.
But for the API-supporter exchanges, Blockfolio works great.
Since ARK holders will receive a lot of staking rewards, it'd be good to have a portfolio-management application which monitors our wallets and automatically registers stake rewards and other transactions.
I'm a bit busy right now to check out Abra, the new platform which supports ARK. If anyone tries it, please let me how it fares.
I believe you are misunderstanding what ABRA is. ABRA is an investing platform. Think of it as an exchange in your hand, it also allows you to purchase with your bank account or credit cards directly inside the ABRA app. With over 500k downloads, this opens the door to many traditional and new investors/traders.
