## Version history (last 2 releases)

### 2.0.1 — 2026-08-10

This update brings a large set of fixes to navigation, ride data accuracy, and Bluetooth connectivity.

NAVIGATION
• Distances and speeds now follow your region's units automatically — metric countries no longer see miles.
• Destinations with no cycling route are now caught in the search screen and clearly reported, instead of opening an empty navigation screen.
• Fixed a hang where the app could stay on "Starting navigation..." indefinitely and had to be force-quit.
• Fixed a hang where tapping search right after closing navigation could leave the app stuck on "Opening search...".
• Clearer messages when a route can't be built: destinations out of cycling range, temporary service issues, and genuine network problems are now told apart, instead of always asking you to check your connection.

RIDE DATA
• Fixed trip distance (DIST) and ride time (TIME) being over-counted — the slower you rode, the larger the error. Both now show true values. After updating, the same route will read lower than before: the earlier figures were inflated, not the new ones reduced.
• Speed now returns to 0 when the bike is stopped or in neutral, instead of freezing at the last value shown.
• The reverse-gear indicator now reflects the controller's actual state.

BLUETOOTH
• The available-device list no longer shows the same controller twice after a power cycle.
• Continuous scanning: bikes appear as soon as they power on and disappear a few seconds after going offline — no manual refresh needed.

### 1.0 — 2026-05-31
