Main Activity contains Spinner view to select currency (searchable list contains 100 most worth cryptocurrencies - sorted descending by market cap). It also allows to set date range - actual or archival, chosen from date picker.
There is, as well, chart which shows selected cryptocurrency price changes (with calculated percentage value of price trend) in selected time period - app allows to select last 1 year, 1 month, 1 week and 24 hours.

Recently added feature is handling of price alerts. Click on bell icon causes start of activity containing list of alerts and switch to enable functionality. Button in corner allows to add new record and trash icon - delete it. After enabling, service of application is doing check of all observed prices in every 20 minutes. If condition of alert is fulfilled - notification appears.
