Trends shows how your training and recovery changed over a period you choose. Every chart sits on one scrolling screen, and one period menu controls all of them.
01Opening Trends
Tap the Trends tile on Today. The tile shows your current training load ratio, for example Training Load Ratio 1.05, with a 7-day training load sparkline. An arrow points up or down when the ratio moved by more than 0.01 since the previous day with a value. You can also touch and hold the Titan icon on your Home Screen and choose Trends. See quick actions.
If the tile reads No data, Titan has no training load ratio yet. Tapping it explains what is missing instead of opening Trends. Record activity over more days to build the comparison.
02The period menu
The menu at the top of the screen sets one period for every chart. Choose 30 Days, 60 Days, 6 Months or Year. Trends opens on Year. Pull down to refresh.
Tap or hold a chart to read the values for that day. Weekly bars read for the whole week. The selection stays until you tap outside the chart. A day without a value reads No data, and the line breaks there instead of dropping to zero.
03Training load
The first chart plots two lines. Long-term load reflects about six weeks of training and short-term load about one week. A day's load comes from your minutes in each heart rate zone, and a workout without heart rate still counts by its length and activity type. Training load covers the math.
A shaded band labeled Typical marks the middle 50% of your long-term load values in the period. A quarter of the days sat above it and a quarter below. The band describes your own history and sets no target. It needs long-term load on at least 28 days, and on at least 80% of the days in the period. Until then the chart reads "Range needs 28 days of training load".
The line under the chart shows the latest load ratio, short-term load divided by long-term load, with a word for its band.
| Ratio | Label |
|---|---|
| Under 0.8 | Low |
| 0.8 to 1.4 | Optimal |
| 1.4 to 1.6 | High |
| 1.6 and above | Risk |
A ratio above 1 means your recent week ran heavier than your recent normal. Below 1 means lighter. The line reads No data when no day in the period has both loads.
04Training load focus
Focus splits the period's load into three intensities, using the same zone weights as training load. Low aerobic covers Zones 1 and 2, High aerobic covers Zone 3, and Anaerobic covers Zones 4 and 5. Each row shows the load and its share of the total. With no zone time in the period, the section reads "No zone minutes in this period".
05Cardio distribution
Each bar adds up your minutes in Zones 2 to 5 for one calendar week, stacked by zone. Zone 1 is left out of this chart only. It still counts toward training load and focus. The first and last weeks of the period can be partial. See heart rate zones for how the zones are set.
06Recovery vs exertion
This chart draws your daily Recovery score, out of 100, and your Exertion score, out of 10, on one shared scale. A run of days with exertion climbing while recovery falls is the pattern to watch.
07Training balance
Training balance multiplies Exertion by 10, subtracts Recovery, and averages the result over the last 7 days. The chart draws a reference line at zero. Above it, exertion has been ahead of recovery. Below it, recovery has been ahead. See training balance for the full calculation.
08Cardio fitness
Cardio fitness plots your VO2 max as Apple Health records it, in ml/kg/min.
09Heart-rate recovery
Heart-rate recovery plots how far your heart rate fell in the minute after a workout ended, in bpm. A bigger drop is better.
10Training adaptation
Training adaptation plots HRV variation. It measures how much your daily HRV moved over the last 30 days, as a percentage of its average. A steadier HRV gives a lower number. Each point needs HRV on at least 7 days and on at least 60% of those 30 days.
11Distance
Distance adds up the distance of your recorded workouts each day, in kilometers or miles depending on your unit setting. Walking outside a workout does not count.
12Mood
Mood appears only when you log State of Mind in the Health app. It averages your entries by day on a scale from −1, very unpleasant, to 1, very pleasant.
13Activity filters
Cardio fitness, Heart-rate recovery and Distance each have a menu with All Activities, Running, Cycling, Walking, Hiking, Swimming, Rowing and Other. Other covers every remaining workout type.
For Distance, Titan adds up only workouts of the chosen type. For Cardio fitness and Heart-rate recovery, Titan keeps a day's value only if you recorded a workout of that type that day. Other days show as gaps.
14When a chart is empty
Titan draws saved history first, then fills in missing days from Apple Health in the background, so charts can complete over the first minutes after setup. If Titan cannot read Health, the screen reads "Allow Health access". Turn on access in the Health app, then pull down on Trends to refresh. See Health permissions.
If a chart stays empty, check that Health records that data. Cardio fitness needs VO2 max readings, Heart-rate recovery needs workouts with a recovery reading, and the zone charts need workouts with heart rate. For anything else, reach us through the contact page.
