Change Logs
Coaster Fusion
These are the changes related to the algorithm that generates the roller coaster analysis. You do not need to upgrade — any track uploaded will be analysed using the latest algorithm.
Coaster Logger
These are the changes to the Coaster Logger app — usually pertaining user interface and user facing feature changes.
-
Export beautiful poster-style images and reel-style videos of tracked 3D coaster models with the new advanced composer — with full control the model, colours, background, text and watermark.
Indication when an analysis is being downloaded.
-
Improved clarity around location permission prompting.
-
Enhanced button clarity when viewing plots.
Streamlined the coaster track renaming experience.
Improved lifetime trend plots to better handle large gaps between coaster rides.
-
Fixes an issue where the scream loudness during your coaster ride is not captured.
-
Fixes a bug where the Hyper, Giga and Strata coaster badges are computed incorrectly. You may have to track your next coaster after this update for this bug fix to apply.
Fixes a bug where the Astronaut badge is computed incorrectly. You may have to track your next coaster after this update for this bug fix to apply.
Fixes a bug where the local time of the roller coaster is not displayed properly.
Fixes a bug in the airtime visualisation widget.
-
Additional tips and hints shown throughout the interface.
-
Improved handling of timestamps when you have ridden roller coaster across multiple time zones.
Improved reliability of Watch Only recording transfer.
Improved permission prompting when using the Watch to recording.
-
Bug fixes
-
Updated Samples
Fixes an issue where the Sample Gallery would not load.
Fixes an issue with coaster filtering
-
Initial release.
-
Improved reward function when integrating acceleration information, taking into account barometer information:
iPhone enhancements, specifically in GPS-denied environments (e.g. indoor rides) (415bfb18)
6% improvements in coaster shape estimation.
4.5% improvements in speed estimation.
7.6% improvements in coaster length estimation.
Apple Watch specific enhancements (37f150f1)
A 42% reduction in the RMSE of maximum height estimation.
Overall improvement across the entire validation dataset (d8b4305c)
General coaster shape expected to improve on average by 3%, with minimal improvements to height estimation (<1%).
3.5% improvement in speed estimation expected.
More tolerant to large and variable gaps in barometer measurements, especially from Apple Watches. However, note that the altitude information will be degraded accordingly.
Enhanced walking detection algorithm to improve recording trimming, allowing the analysis the focus on the true roller coaster portions.
-
Fixes a critical issue where Watch Only recordings of coasters will not parse at all.
Improved representative point calculation, using all available GPS points during the recording, not just the ride portion.
Fixes a critical issue with Watch recordings exhibiting incorrect altitude fusion due to coordinate system mismatch.
-
Initial release.
Note: Updates to Coaster Fusion will not alter old analysis, though you can always re-upload theme for analysis. Once re-uploaded, though, you will not be able to go back to the previous analysis.
