Your time is precious. C-Time shows you where it really goes - automatically. How many hours did you actually work this month? How often did you make it to the gym? C-Time answers these questions without you lifting a finger: define your place once, and the app clocks you in when you arrive and out when you leave. No buttons to press, no timers to forget, no extra battery drain - it uses Apple's geofence technology, not GPS. Open the app and your numbers are just there: today, this week, this month, this year - clean statistics, automatically backed up to iCloud. WHAT C-TIME DOES FOR YOU • clocks you in and out automatically at your place - work, gym, wherever • shows the running time live on the lock screen, in the Dynamic Island and on Apple Watch • history per day, month and year with clear charts • set a daily goal per place and see today's over/under at a glance - turns green when you reach it • a Home & Lock Screen widget with your goal ring - progress at a glance • add a note to any check-in - shown in history, in the CSV export and on the main screen • automatic daily break deduction per place - e.g. 30 min once a day passes 4 hours (off by default) • notifies you on arrival and departure • manual clock in/out and editing whenever you need it • automatic iCloud backup, plus backup to a file and restore • speaks English, German, Spanish, French, Italian, Japanese, Korean and Chinese Set it up in one minute. Forget it. Know your hours. C-Time Lite is free: monitor one place and see all details for 4 weeks. The Pro upgrade (in-app purchase) removes all limits: • monitor up to 20 places (an iOS limit) • monitor your time indefinitely • export your data: beautiful PDF report, CSV, e-mail, backup file TIPS □ The automatic mode runs at its best when Wi-Fi is enabled. □ C-Time uses the same technology (geofence) as Apple's "Reminders" app. ================================================ What customers have said about C-Time: ================================================ △ Incredible app. I always forget to clock my time.

All needed time stamps are logged automatically!! △ Perfect app. Simple to use and helpful to have the overview where time was spent. Congratulations! △ Great App to know where you spend your time.

Funciona bem e tem boas funcionalidades. Recomendo. △ 매우 좋아요. 자동 체크인 체크아웃 해주고, 자신의 동선 자동 관리가능하며 개인적으로 장소들을 관리할 수 있다는 점이 아주 마음에 듭니다. 앞으로 더 기대되네요

BZ-Battery reads the high-voltage battery in a Toyota bZ4X and shows you what the car keeps to itself, on your phone and on your CarPlay screen. You need a Bluetooth LE OBD adapter, plugged into the port under the dash. It is tested with an OBDLink CX; vLinker and Veepeak should work too. The cheapest "ELM327 mini" clones often can't read this car. The adapter is not included. What you get: • Charge, power and current, live • Every cell voltage, with the weakest one marked • All pack temperature sensors • Battery health, as the car itself reports it • Measured pack capacity, tracked over months • The 12 V battery's voltage • Every drive and charge kept, with the energy it used • Five dashboards. Pick the one you like. • CarPlay: charge, power, cells, temperature and 12 V on the car's screen Which cars: Toyota • bZ4X 2026 • bZ4X 2022–2025 • bZ 2026 • bZ4X Touring 2026 • bZ Woodland 2026 • C-HR+ 2026 • C-HR 2026 • bZ4X / Bozhi 4X 2024 (China) Subaru • Solterra 2022–2025 • Solterra 2026 • E-Outback 2026 • Trailseeker 2026 • Uncharted 2026 Lexus • RZ 2023–2025 • RZ 2026 It only reads. The app cannot change a setting, clear a fault, or write anything to the car at all. That is enforced in the app. No account, no ads, no tracking. Your readings, history and settings stay on your phone. What the app does send is anonymous and never identifies you or your car: the car model you picked, a short report of how each connection went, and battery-health figures for a study of how these packs age. You can switch the reports and the study off in Settings. Drive summaries are sent only if you turn that on. No car to hand? There is a demo mode built in, so you can look at every screen before you plug anything in. An independent app. Not made by, affiliated with, or endorsed by Toyota, Subaru or Lexus.
