Swipe to the left to see your most recent trips. To find a trip further in the past, pull down from any trip overview, select a week, day and trip and you will be navigated to the particular trip.
Tap "Flo" in the upper left corner of the app to reveal the main menu on the left side of the screen. Tap "All Trips" for an overview of past trips.
The trips are grouped into weeks. By default, the current week is shown when opening "All Trips". You see all recorded trips that week in the lower half of your screen. If you want to look at the details of a specific trip, simply scroll through the list and tap the one you're interested in. The trip is shown on the map along with all relevant metrics: your score, distance, driving time, date and time, speed, and addresses.
To see the trip in more detail, tap on the map image of the map. Green bullets indicate where you did well and red bullets show where you lost points. You can zoom in on the map and tap the bullets to see the details -- e.g., one green bullet may say "+15 Easy brake", meaning you earned 15 points because you were easy on the brakes at that spot.
Tap "This Week" to see a dropdown list of all past weeks. Select a week and all recorded trips appear, including total kilometers, trips, and your average score.
