Great app
Response from developer
Thank you. 1.5, out now, colours the track by grade and the route card shows the maximum uphill and downhill grade as a percentage; the chart under the map also carries heart rate, power and cadence when the file has them. If there is a file it gets wrong, info@objectgraph.com reaches me directly.
Simple but beautiful
Thanks for sharing!
Response from developer
Thank you. 1.5 adds a workout summary with moving time, pace, gain and loss and splits, and charts any sensor the file carries, which should help with sizing up a tour before riding it. Sample files and a demo you can scrub are on objectgraph.com/gpxexplore.
