Data source: Core Motion
Stepluma uses step values provided by iOS through Core Motion. The app does not measure steps using GPS and does not reconstruct routes.
Steps
Step values come directly from the pedometer data iOS provides and are refreshed at regular intervals as the iPhone delivers new values.
Distance
A displayed distance is an estimated iPhone/Core Motion distance, not a GPS-accurate route. Stepluma does not use GPS and does not reconstruct a route.
Floors
Floors climbed and floors descended are shown when your device provides that data. Not every device or situation provides these values; individual steps of a staircase are not measured.
Missing Data
Missing values are not automatically treated as inactivity. A device not being carried, missing permission or unavailable system data can all be causes.
Partial and Current Days
Current and detectably incomplete days are considered in context. They should not affect trends as though they were fully recorded.
History
History aggregates available daily values for selected periods. Charts and heatmaps do not modify source data; they present it more clearly.
Goals
Goals are personal reference values you define. Meeting or missing one says nothing about health or personal worth.
Forecast
Forecasts are cautious estimates based on available patterns. They are not guarantees and become less certain with sparse or irregular data.
Activity Score
The Activity Score condenses selected personal activity signals into an accessible orientation. It is not a health value or medical classification.
Personal Range
Personal Range compares you exclusively with your own suitable history. It is not a health norm and does not produce judgements such as "healthy", "too little" or "too much".
Time-of-day Pattern
Stepluma detects your most active time of day from your local history. This is a descriptive observation of your own data, not a psychological interpretation.
Weekday Pattern
Similarly, a typical active weekday and a weekend-versus-weekday comparison are derived from your own history — purely descriptive, without judgement.
Active Pace
Active Pace is an estimated average pace derived from available movement data during active periods. It is not a medical walking speed and not a performance measurement.
Walk Check
A Walk Check reviews a walk you intentionally start, roughly three minutes long, using available movement data and your personal context. It does not test for illness or replace professional assessment.
Step Length in Walk Check
If you have entered your height, an estimated step length within a Walk Check can be placed descriptively in context. Weight is not artificially used for this.
Consistency in Walk Check
Consistency describes how even your pace was within a single Walk Check. It is a descriptive metric, not a fitness or health assessment.
Movement Profile
The Movement Profile summarizes personal rhythms and developments from steps, patterns and Walk Checks. It stays local on the iPhone and serves your own overview only. Stepluma does not track continuous daily movement time, walking time or running time, and does not calculate a biological or movement age.
Trend
Trends smooth short-term variation to make direction easier to understand. Individual days may differ from the displayed trend.
Privacy and local-first
All analysis described here runs locally on your iPhone. Stepluma does not automatically transmit movement data to a server and needs no account to do so.
Limitations
Sensor and system data may be missing or inaccurate. Statistical summaries simplify reality. Stepluma knows neither your full daily life nor medical background and therefore draws no medical conclusions.
