Apple Watch Ultra (AWU) Divelog reads your recorded dive data from the Apple Watch Ultra and displays your dives. For this purpose, AWU Divelog is integrated with the Health App and the HealthKit framework and accesses the depth and temperature data stored on the phone. Your dives are listed along with the most important data, such as duration, depth and temperature, sorted by time. You may sort and group your dives by different metrics. Detailed data can be displayed for each dive. In the detail view depth and/or temperature are graphically displayed and can be shared (e.g. by AirDrop). In the detail view it is possible to swipe through the dives. In addition, overall statistics of all or selected dives are automatically displayed in the upper area of the list view. After a dive, the data is read from the Apple Watch Ultra and added to AWU Divelog. Manual updating of the list is also possible. Short surface breaks during the dive are detected and are not interpreted as separate dives. Dives can be exported as Universal Dive Data Format (UDDF) XML file (e.g. by AirDrop). The UDDF file can be imported into common dive software (e.g. Macdive and Subsurface). AWU Divelog is available in English and German. It will use your iPhone's regional units of measurement for depth and temperature (metric vs imperal). Hard Facts: - Reading recorded dive data from your Apple Watch Ultra. - List your read dives immediately after diving on your iPhone. - Statistics about your dives. - Graphical display including export for dive depth and/or water temperature. - Select individual dives. - Sort and group your dives. - Share the chart as PNG/JPG (e.g. via social media). - UDDF export of the dives

Your chain doesn't care what day it is. It cares how far you've ridden. Bike Assistant tracks every part on every bike by the kilometer, by riding hours, or by charge cycles, so you know what's worn, what's due next, and what can wait. No spreadsheet, no guessing, no "I think I changed that in spring". HOW IT WORKS Connect Strava, and your bikes and rides import themselves. Add the parts you care about. Start typing a brand and we suggest one. A custom part can count riding hours instead of kilometers. Get a nudge before something is due, instead of after it's ruined. YOUR WHOLE FLEET ON ONE SCREEN See at a glance which bike is dialled in, which one could use some love, and what service is coming up. Open a bike for every component on it, its mileage, and how much life it has left. Notes live on the bike too: tire pressures, fit numbers, what the workshop said. CHAIN WAX, TRACKED PROPERLY Log wax cycles or drip top-ups. See the kilometers since the last wax, get reminded when the next one is due, and keep a complete wax history per chain. Waxing a whole batch at once? Record the batch in one go. And running several chains in rotation on the same bike is the normal case here, not an edge case. BATTERIES, THE SAME WAY Di2, AXS and power-meter batteries are parts like any other. Log a charge, watch the count, and see it beside your chains. The reminder speaks hours until the next one. THE RIGHT BIKE ON A RIDE Picked the wrong bike when you headed out? Change it in the Activity Log. We update it on Strava too, so the kilometers land on the right bike and the right parts. PARTS THAT KNOW THEIR OWN AGE Chains, cassettes, chainrings, cranksets, bottom brackets, brake pads, tyres, batteries: each with brand, expected life and a wear status that updates itself as you ride. Custom parts can count riding hours instead of kilometers. Move a part to another bike, retire it, or bring an old one back into service. The mileage follows the part, not the bike. TUBELESS SEALANT ON THE CALENDAR Sealant doesn't dry out by distance, it dries out by time. Set a refill interval in days per tyre, record fresh sealant or a top-up, and let the app keep the clock. It keeps counting while the bike hangs in the cellar. TWO-TAP SERVICE LOG Quick Service logs a wax, a sealant top-up, a chain swap or a battery charge from anywhere in the app. Backdating is expected, not an afterthought: you did the work in the garage, you log it on the sofa. REMINDERS THAT ARRIVE IN TIME Push notifications when a chain needs waxing, when a service comes due, or when a part reaches the end of its expected life. Everything also lands in an in-app inbox, so nothing is lost behind a dismissed banner. WHAT BIKE ASSISTANT IS NOT No training analysis, no power curves, no leaderboards. Your bikes and rides are only ever shown to you. The one public place is Ideas, an optional board where riders suggest features under a name they choose. This app is about the bike, not the ride. WHAT YOU NEED A Strava account, and the free tier is fine. Your bikes and rides come in from Strava, and that is the only way in. If you move a ride to another bike here, we update that activity's bike on Strava. We never post to your feed and never create activities. BIKE ASSISTANT PRO Everything above is free. The optional weekly Pro subscription adds analytics (cost per kilometer, part lifespans, how your services perform), order import from a receipt photo or PDF, other riders' bikes, unlimited notes and indoor settings for past rides. Payment is charged to your Apple Account at confirmation. It renews automatically unless cancelled at least 24 hours before the period ends. Manage it in your Apple Account settings.
