A world clock app for the people in your life. For iPhone, iPhone Duo, iPad, Apple Watch and Mac. Whether your family is spread across countries or your team is split across time zones, World Time Widget keeps you thoughtfully in sync. Add clocks for the cities that matter, give each one a name that means something to you, and know at a glance whether it’s a good time to reach out. Over one million downloads. WORLD CLOCKS See the time in any city, instantly. Add as many clocks as you need and label them the way you actually think of them: “Mum in Sydney”, “Berlin office”, “Charlie deployed.” HOME SCREEN, LOCK SCREEN & STANDBY Your most important world times are always one glance away — no need to open the app. Widgets for every Apple surface, with up to 8 time zones on a single large widget. DAY & NIGHT STATE Every clock shows whether it’s day or night for the person on the other end. So you know before you text. MEETING PLANNER Need to find a time that works across time zones? Drag through the day to find the right slot, without the mental arithmetic. APPLE WATCH Your world clocks on your wrist. A dedicated Apple Watch app and support for multiple complications keep your times visible wherever you are. IPHONE, IPAD & APPLE WATCH Works beautifully across all your Apple devices, with your clocks syncing seamlessly via iCloud. No ads, no sign up. Just your clocks. FREQUENTLY ASKED QUESTIONS Does World Time Widget have a home screen widget? Yes. There are widgets for every Apple surface: home screen, lock screen, StandBy mode, and Apple Watch. You can show up to 8 time zones on a single large widget, so everything you need is one glance away. Can I use custom labels instead of city names? Yes. You can name any clock whatever makes sense to you. “Mum in Sydney” tells you at a glance whether it’s safe to call. “Dev team in Berlin” tells you whether they’re in the office. Your clocks, your labels. Does it work on Apple Watch? Yes. There’s a dedicated Apple Watch app plus support for multiple complications, so your world clocks are always on your wrist. Can I convert time zones and schedule meetings? Yes. The built-in meeting planner lets you drag across the day to find a time that works for everyone, across as many time zones as you need. No mental arithmetic, no switching between apps. How many cities can I add? As many as you need. You can show up to 8 time zones at once on a large widget, and you can add more clocks to the app itself. Does it handle daylight saving time automatically? Yes. World Time Widget updates automatically for daylight saving changes worldwide, so your times are always accurate. Does it work on iPad as well as iPhone? Yes. World Time Widget works across iPhone, iPad, and Apple Watch. Your clocks sync across all your devices via iCloud. What makes it different from Apple’s Clock app? Apple’s Clock app is useful, but limited. World Time Widget adds a day/night indicator for every clock so you can see at a glance who’s awake, lets you use personal labels instead of city names, and puts your world clocks on your home screen, lock screen, StandBy, and Apple Watch with far more flexibility. Apple Clock also caps out at 4 cities in a widget. World Time Widget shows up to 8. Is there a free version? World Time Widget is free to download with a premium upgrade available for additional features.

YOUR EV COSTS, CLEARLY TRACKED. VoltSlide is a private iOS app for EV owners who want real cost and efficiency insight — without daily data entry. Most EV trackers expect you to log every charge. VoltSlide doesn’t. Log public charging and expenses as they happen, then enter your home charger or utility totals once a month. You get a complete picture of your EV’s true cost per kilometer, with far less friction. HOW VOLTSLIDE WORKS ON THE GO Whenever you charge away from home or incur a vehicle cost, log it right away: • Public and DC fast charging — kWh, cost, session fees, and idle fees • Optional odometer, location, and receipt photo • Maintenance and expenses — registration, repairs, accessories, and more • Seasonal tire swaps to track how different sets affect efficiency AT HOME With a connected Level 2 charger, skip the nightly log. On the 1st of each month, enter your charger app’s cumulative kWh and cost (ChargePoint, Grizzl-E, Wallbox) in one entry. Optional monthly reminders keep home energy up to date. YOUR GARAGE Keep everything about your EV in one place: • Multiple vehicles — photo, name, and km or miles per car • Odometer readings and distance travelled • Service history with optional dated reminders • Expenses, trips, and tire sets with install dates and odometer snapshots • Purchase price, date, and optional depreciated value for ownership reporting DASHBOARD See how your EV is performing at a glance: • Efficiency gauge with km/kWh or mi/kWh and trend vs the prior period • Energy donut — home, public, and DC fast charging split • Distance travelled with a trend chart for your selected range • Energy cost, total operating cost, and cost per km or mile • Quick date chips: 3 months, month, year, all time, or custom range • Home / Public / All scope to focus on the costs you care about COMPARE TO GAS See how your EV stacks up against gas over the same distance and date range. Choose NRCan 2026 ICE class averages — subcompact, compact SUV, sedan, or pickup — or enter your own efficiency and gas price in Settings. Share a comparison card. REPORTS Custom date-range reports: • ENERGY — home, public, and total kWh • COSTS — energy, service, expenses, and all-in total; depreciation shown separately • RATES — cost per kWh, per day, and per distance unit • Monthly and yearly cost predictions from your recent driving • PDF export plus shareable stat and prediction cards LOG Three entry types, one clean interface: • Public charge — DC fast or AC/L2 with fees, location, photo, and optional odometer • Home energy — monthly kWh and cost from your smart charger or utility bill • Odometer — standalone mileage readings • Edit saved entries — adjust cost per kWh, log type, or odometer after the fact IMPORT AND EXPORT Your data stays portable: • Full VoltSlide CSV backup — vehicles, charging, odometer, service, expenses, trips, tires, and photos • Import a backup to restore or move data between devices • Import from Road Trip (CSV) — fuel, maintenance, and tire history • Choose the destination vehicle, or create a new one on import OPTIONAL iCLOUD SYNC Turn on iCloud sync to keep a garage tied to your Apple ID. VoltSlide keeps separate on-device and iCloud garages — sync switches to iCloud; it does not merge automatically. Export a CSV backup first. After changing sync, swipe VoltSlide away and reopen. PRIVATE BY DESIGN • No account required • No ads, tracking, or third-party analytics • Your records stay on your device • iCloud sync uses your Apple ID — VoltSlide does not collect or sell your data DESIGNED FOR REAL EV DRIVERS VoltSlide is for people who want honest answers: What does it cost to drive my EV? How efficient is it across seasons? Am I saving vs gas? No spreadsheet or daily logging required. Questions or feedback: support@voltslide.app Privacy policy: https://voltslide.app/#privacy
