I'm tired of mental math when finding time for the call across multiple timezones. You too? Great news, I've made an app for that! It's not for everyone, if you have all the team in google calendar – that's a great perk! But if you have calls with people outside of your organization and can't see their calendar, the alignment in messages or on the call becomes a pain in the... back. That's why Time Zone Slider is a visual tool to convert time for international meetings, clients abroad, travel, and family around the world. Time Zone Slider is what it says on the tin – it shows all your time zones side by side as you drag. No math, no guessing, no daylight saving surprises. Perfect for remote teams, international calls, and anyone tired of Googling "what time is it in Tokyo." Home screen widgets are available too. Add one and check world times at a glance. --- WHAT IT DOES - Drag the time drum and watch all zones update in real time - Color-coded working hours so you can see who's available at a glance - Spot the overlap — find the window where everyone is actually online - One tap to create a calendar event (Apple or Google) with timezone handling done for you - Copy all times as clean text to paste into Slack, email, or a message - Home screen widget — check times without opening the app --- WHO IT'S FOR Remote teams. Freelancers with clients abroad. People with family in other countries. Anyone who has ever Googled "UTC+5 to EST" and wished there was a better way. --- Built by one person, used by real humans. If something feels off, reach out — I read every message. --- Apple Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
