@Tracker
Routes, workouts and statistics.
Apps
Practical apps for sport and design.
Aurelius Technology B.V. develops small, focused apps that do one job well: @Tracker for routes and training, and @Design Studio for clear diagrams on the Mac.
@Design Studio
Flowcharts and diagrams.
Products
Two apps, each with a clear purpose.
@Tracker is sporty and motivating: it comes along during training and makes progress visible. @Design Studio is a calm, native Mac app for anyone who wants to create a clear diagram quickly, without heavyweight software. Both apps are developed and published by Aurelius Technology B.V.
@Tracker
Record your route and see your progress.
For running, cycling, skiing, rowing and hiking — on iPhone and Apple Watch. Record your route, view relevant statistics, set up workouts and follow your development over time.

@Design Studio
Create simple diagrams on your Mac.
A native Mac app for flowcharts, process maps, decision flows, app architecture sketches, simple organisation charts and planning diagrams — no account, subscription or cloud setup.

@Tracker
Sports data you can use right away.
During the activity you see where you are and how you are performing — on your iPhone or straight from your Apple Watch. Afterwards you analyse route, pace and progress, so every training session contributes to the next goal.

- Personal Records: see your all-time best for every sport.
- Set up interval workouts, countdown and workout preferences.
- Automatic backup of your tracks in your own iCloud.
@Design Studio
Native diagrams without a heavy setup.
Start from a blank canvas or a starter template. Add shapes, text and connectors, work with layers and grouping, and export your diagram as PNG or PDF.
- For flowcharts, process maps and decision flows.
- For app architecture, planning and documentation.
- Local
.dsdocfiles and no account required.
@Design Studio features
Light enough for daily work, complete enough for clear sketches.
Exactly the tools you need to sketch, organise and share ideas — without turning a quick task into a big design project.
Start quickly
Choose a starter template or begin with a blank canvas. Add shapes, free text and connectors.
Finish neatly
Use align, styling, layers, grouping, lock, hide, reorder, undo and redo to refine the diagram calmly.
Share as a file
Export the full page or just your selection as PNG or PDF for documentation, planning or meetings.
Privacy
Local documents, no unnecessary data collection.
@Tracker stores data locally on your iPhone and backs up your tracks to your own iCloud — nothing goes to Aurelius servers; the official App Store privacy label reads "Data Not Collected". @Design Studio is built as a local macOS document app: diagrams are stored locally or in folders chosen by the user, and the app collects no user data.
