I've compared your application with another app called crypto pro (on my iOS) and it seems to have most of the metrics to track the portfolio of investments and the % of prices and losses. I also like the charts. Would a candle stick based chart be possible to implement and also possibly a night mode?
Would you mind elaborating on what all information / data would you be providing access to with your API?
Also, I really liked the interface. It's very nice!
Thanks for your detailed feedback!
We are still in beta, so we are testing a few features. About API source, as explained in the terms of use, we currently use CoinCap API, but we probably will switch to direct data from exchanges if we get interesting user base within 6 months.
Candlesticks were included in the initial project but we currently only show line charts because we decided to go live earlier in order to get feedback from users.
Just switched free plan limitation to 3 coins as you and other people suggested us. About the night mode, we have just added it to the feature list.
