TN Splits View
· v1.0.0
About
TN Splits View is a running data field that shows your lap splits in a colored list and lets you log blood lactate measurements directly on your watch during a run — no phone needed.
### Lap list
Each completed lap appears as a row with lap number, time, distance and pace. Rows are color-coded by pace so you can read your effort at a glance. The current (in-progress) lap is shown live at the bottom, separated by a line, and updates every second. Pace thresholds and colors are fully configurable in settings.
### Three list layouts
- MIN — compact 8-row list
- MID — 5-row carousel with the active lap enlarged in the center
- MAX — single large card for one lap
Choose a fixed layout in settings, or enable "All" mode and tap the center of the screen to cycle MIN → MID → MAX on the run.
### Blood lactate logging (optional)
**How you get the value:** This app does not measure lactate. You obtain your blood lactate value yourself, using your own analyzer (for example a portable lactate meter with test strips) that is not connected to the watch. The app only lets you log the number you already have. Measuring lactate is not a function of this device.
Enable lactate input in settings. A water-drop button appears on the right edge of the list.
How to log a measurement:
1. Tap the drop button on the right to open the input screen.
2. Adjust the value with the corner zones: top-left +1, top-right +0.1, bottom-left -1, bottom-right -0.1. The value starts at 2.0.
3. Tap OK (center-bottom) to save. The reading is written into the activity and appears in the list with a drop icon and timestamp.
4. To go back without saving, tap the recycle button on the left edge.
Lactate values are recorded into the FIT activity as a developer field, so they sync with your run and can be read later.
### Tap controls summary
- List view: center = switch layout (in All mode), right edge = open lactate input
- Input view: corners = adjust value, OK = save, left edge = back
Units (km / miles) follow your watch system settings.
**Note:** The data field must be on screen from the start of the activity to capture all laps. Designed and tested for Forerunner 955, 965 and 970.
