Your sweat profile changes with every workout. Intensity, environment, sleep, and where you are in a training block all affect how much fluid and electrolytes you lose. Nix Solo already lets you filter workouts by metrics like Nix Index, RPE, and location. Tags let you add the context the app can’t measure on its own.
Nix Solo includes a set of preloaded Tags such as “Hill Work,” “Tempo,” and “Intervals.” You can also create your own, and any new Tag is saved to your list for future workouts. Once your workouts are tagged, you can filter your Sweat Profile or Workouts list by one or more Tags to see how your sweat losses compare across different sessions.
You can tag a workout from the Workout Summary screen at the end of a completed session, or go back to a past workout and add Tags at any time.
From the Workout Summary, tap the Tags field

Tags keep your sweat data organized and make patterns easier to spot. Tagging workouts by type (training vs. race or game day, intervals, hills) or by influencing factors (poor sleep, menstrual cycle phase, travel, illness recovery) helps you see what may be shifting your hydration needs from one session to the next.
You can filter by Tags from two places in the app.

Your sweat profile is dynamic, and the context around each workout matters. The more consistently you tag, the clearer the picture becomes of how your training, recovery, and environment shape your hydration needs.
