Your Data, Your Rules
We believe athletes should own their performance data. Export your original files anytime. No hidden mining, no lock-in, just pure analytics.
Quantified Self.io
Quantify. Analyze. Improve.
One Dashboard. Every Activity.
Bring Garmin, Suunto, and COROS activity data into one private training dashboard.
Upload files, analyze performance, and keep Garmin or COROS activities syncing to Suunto.
Seamless Integration With
Import Garmin, Suunto, and COROS history into Quantified Self. Garmin supports up to 5 years per request, while COROS history imports are limited to the last 3 months.
Connect Garmin, Suunto, and COROS once. New activities from connected services sync to Quantified Self automatically.
Garmin -> Suunto and COROS -> Suunto sync are built in, with reliable and instant sync for newly imported activities, plus catch-up sync for events already stored in Quantified Self.
Upload GPX routes directly to Suunto from the Services page to keep your route planning and device workflows aligned.
Upload FIT activities to Suunto manually anytime from Services for one-off corrections, missing sessions, or migration workflows.
Reliable and instant analytics for training load, readiness, and execution. KPI and derived charts are built in for decision-ready coaching context.
Compact KPI rows keep key load and readiness indicators visible above your main dashboard grid.
Use recovery, readiness, execution, and sleep views computed from your stored training history.
Build manually or start from presets across Curated, KPI, Custom, and Map tiles. Tune tile filters, map style, and clustered heatmaps per tile.
Explore 7 chart types, heatmaps, clustering, and route-level analysis with gradient and speed overlays across 12 map styles.
Import and sync across Garmin, Suunto, and COROS, then analyze your complete activity dataset from one dashboard.
Turn focused training questions into chart-backed answers grounded in your stored activity data.
Specify a metric, activity type, and date range to keep each answer precise and directly usable in training decisions.
Receive aggregate trends, multi-metric summaries, activity lookups, or latest-activity answers that match your prompt intent.
If a request is unsupported, AI Insights suggests better prompt paths so you can quickly land on a supported query.

Your activity questions, chart-backed answers.
Every run, ride, and hike — visualized on a single map. Explore your entire athletic history.
We believe athletes should own their performance data. Export your original files anytime. No hidden mining, no lock-in, just pure analytics.
Merge same-session recordings, choose a reference device, and compare hardware across GNSS accuracy, sensor agreement, stat deltas, and data-quality artifacts.
Combine recordings from multiple devices into a benchmark event, keep it out of normal training totals, then pick reference and test activities for a clean device-to-device report.
Compare GPS tracks point by point and quantify trace disagreement with CEP50, CEP95, RMSE, max deviation, and total distance difference.
Grade shared streams with correlation, MAE, and RMSE, then surface dropouts, stuck values, and cadence-lock warnings before a device shapes your decisions.
