FrontSpin Chrome Extension

If you prefer to work in Salesforce directly, FrontSpin offers a Chrome Extension that acts as a side-panel next to Salesforce. 

You can install it from the Chrome Web Store: https://chrome.google.com/webstore/detail/frontspin-chrome-extensio/dnajgbdlejjkphklpbmahjnakoclolkb?hl=en-US

This will work in Salesforce Lightning or Classic mode. It will add little blue icons next to the names and phone numbers of any leads/contacts in Salesforce...

Clicking on the blue icon next to the lead/contact's name will load them up in the FrontSpin Chrome Extension...

And clicking on the blue icon next to a phone number will auto-dial that lead/contact...

You will see at top of the lead/contact there are two tabs: CONTACT and TIMELINE. 

The TIMELINE tab will be where you can enter your call notes, set follow-up activities and see activity history...

Note: You can expand the Chrome Extension to full-screen and it becomes just like the web version. In full-screen for example, you might choose a List/Playbook to dial and then shrink the FrontSpin Chrome Extension back down to the side-panel view, allowing you to Power Dial through your List/Playbook that way...
