Consider Snapping in every morning to the individual or individuals you have continuing streaks with an expected routine. Just send a note and inform the other user that they didn't return the Snapback or sending a message. As you run out of time to saving the streak, you'll see a tiny hourglass button appears next to your target or someone else. To all of you, it means the time has run out. Snapchat hasn't publicly announced how long this would run, so if we were to estimate, you're presumably staring at only four hours remaining before the streak expires, which implies the hourglass shows around twenty hours from the last Snap exchange.  A text message doesn't count against your streak, but keep a picture, videos or emoji in mind as well as your reply for your streak partner.
