Sparkbook shuffles favorites you're falling out of touch with to break your habit of calling the same few people.

As time goes on, the memory of your last conversation fades. Keep it alive and pick up where you left off by taking brief notes on your call. These notes are easily brought up before you call them next.

You own your data - all your data is stored locally on your phone.

How good are you at staying in touch? The Insights tool tells you whether you're igniting new sparks or strengthening only a few relationships at the expense of others.
