Changelog

Every version and feature since the first release — transparent and complete.

🍎 iOS · Version 1.0.0 Build 44 · 27 Sep 2026

What's inside version 1.0.0

The first full version bundles what grew across several test builds. Those earlier builds ran under v0.0.x and are listed below — that's where you can see when each piece arrived.

🎨 Appearance is yours to pick — light, dark or system in the burger menu, independent of what your iPhone is set to
🌐 Language picker inside the app — German or English straight from the menu, without switching your system language
🔄 Backup 2.0 with a moving service — checksum protection, a choice between “merge” and “replace”, and backups that travel between iPhone and Android
🏎️ RaceBox (25 Hz) & Curve Tracker import — high-frequency GPS data and MotoLeaning databases read in directly, with nothing lost
🌡️ The day in color — the temperature of your travel days as a gradient along the route, broken down by the hour on the Story Card
⛰️ 4,468 mountain passes & 88 Gold Roads — automatic pass detection across Europe, Gold Road crowns and interactive pass maps
📐 Break & accuracy filters — no more phantom kilometers across recording breaks, GPS outlier filter tightened to 25 m
🗑️ Ride trash — deleted rides stay restorable for 30 days

Free to test — via TestFlight

Kurvenfokus for iPhone and iPad runs as a beta through Apple TestFlight: free, no subscription, no hidden costs. All you need is the TestFlight app and an invitation link. Found something that isn't right? Missing a feature? Write to me — I read every message myself, and good feedback often makes it into the next version.

v1.0.0 (Build 44) 27 Sep 2026 Current

● Appearance is yours to pick — light, dark or system, right in the burger menu and independent of what your iPhone is set to
● Language picker inside the app — German or English straight from the menu, without switching your iPhone's system language

Fixes

⚙ The language switch was incomplete — menu entries, the feature overview, dashboard tips, the in-app changelog and the about screen stayed German while the app ran in English. Now fully translated
⚙ Recording breaks no longer count as distance traveled — time gaps longer than 60 seconds are skipped. On our reference ride the distance drops from 262.8 to 260.0 km: not a calculation error, but the end of phantom kilometers
⚙ GPS outliers are filtered more strictly — points with more than 25 m of horizontal error are dropped during import

○

v0.0.26 12 Sep 2026

● Temperature along your route on the Story Card — the track carries the measured temperature as its color, with time and degrees below it
● Passes in the trip overview — the count per travel day, gold dots on the map, and the total among the key figures
● Full-screen trip map — every ride of a trip in its own color, passes labeled by name, zoomable and pannable
● Trip Story Cards in the brand look — brand header, key-figure bar, footer; the map fills the entire image
● Backup 2.0 — backups carry a checksum per ride, and they move between iPhone and Android
● Import a Curve Tracker database directly — with a preview of how many rides it holds
● Import notices are surfaced — for instance when a GPX file has no timestamps and the speed had to be estimated
● Corner diagnostics — shows the detection profile, mode and data quality of a ride on request

Fixes

⚙ Corner detection: a cleaned import lost the calibration of its data source, which cost around 10% of the corners. Affected rides show the right number again after a re-import
⚙ Story Cards: no more black block between map and text, and nothing is cut off at the edge of the daily cards
⚙ Key-figure bar: long values such as elevation gain no longer wrap onto a second line
⚙ GPS gaps no longer produce phantom speed second by second
⚙ Lean angle no longer drops out on short Curve Tracker rides
⚙ Files that live only in iCloud are downloaded in full before the import, instead of being read as empty placeholders

○

v0.0.25 10 Aug 2026

● My Passes rebuilt — 4,468 mountain passes across 27 countries, based on OpenStreetMap; about a third more than before
● Pass map — every pass you have collected as a gold pin, Gold Road passes marked with a crown
● Automatic pass scan — the app searches your rides after launch and reports back with your collection
● Pass markers in the ride list — four styles to choose from, gold badge by default
● Ride trash — deleted rides can be restored for 30 days
● Story Card with or without signature — you decide whether bike and name appear when sharing
● Import status banner — the import runs visibly in the background and the app stays usable

Fixes

⚙ Exports now say clearly when a ride has no telemetry, instead of quietly doing nothing
⚙ Map: tapping a corner pans to it without changing your zoom level
⚙ Data safety: recalculating corners can no longer overwrite rides whose telemetry is not loaded

○

v0.0.24 26 Jul 2026

● Gold Roads — 88 of Europe's finest motorcycling roads, recognised automatically as soon as you ride one
● My Passes — over 3,200 mountain passes detected automatically, with elevation ranking and corner difficulty
● RaceBox VBO import — bring in data straight from the RaceBox Mini S: speed, g-force, gyro (iOS only)
● Curve Tracker import — GPX from the Curve Tracker app (MotoLeaning) including lean angle and speed
● Trip management and ride comparison — group rides into trips and compare two rides side by side
● Automatic backups — daily, weekly or monthly, stored locally on the iPhone only
● More honest statistics — the app asks about implausible lean angles above 50°, and planned routes no longer count towards your figures
● Planning precheck — planned Calimoto routes are checked in advance for whether corners can be determined reliably

Fixes

⚙ Import safety — files brought in by drag and drop also run through the quality and duplicate checks
⚙ Smooth exports — JSON, GPX and CSV export without the app freezing
⚙ Backup precheck — see ride count, period and size before restoring
⚙ Much faster — new storage format stays smooth even with 300+ rides
⚙ Better elevation — more realistic figures thanks to a new smoothing pipeline

○

Free in open testing

v0.0.19 12 Sep 2026 Current

● Backups stay put — a backup can now be saved permanently: to Downloads, an SD card or the cloud. Until now you could only share it, and cancelling the share dialog left you empty-handed.
● Backup and import report in — both show what they are working on right away: "Ride 42 of 284" with its name when backing up, the current step and the number of points read when importing.
● The app is now available in English — fully translated and reviewed by a second model.

Fixes

⚙ Recording breaks no longer count as distance ridden. If you stop on the road — photo, fuel, coffee — the straight line to where you set off again used to be added to your total.
⚙ Corners passing through north get the right lean angle. When smoothing the heading, 359° and 1° were treated as opposites and averaged into the wrong direction.
⚙ GPX files from other sources are evaluated with the same thresholds as on iOS.

○

v0.0.18 10 Aug 2026

● Ready for Android 16 — the app moved to the latest Android target (targetSdk 36) and the whole build stack was modernised. No new buttons in this release; instead the app stays fast and secure on current devices and up to date on Google Play.

○

v0.0.17 29 Jun 2026

● Planned routes treated honestly — no more invented figures ("—" instead), and they stay out of statistics, heat map and comparison

● G-force and lean angle charts reworked — taller diagrams, tidier axes

Fixes

⚙ Missing elevation data shows "—" instead of "0 m"
