ZoneTime lines up every city you care about on one swipeable timeline, so you can see who's awake, spot the best time to call, and share the plan in one tap. No account. No sign-up. No email. No ads. Open it, add your cities, and plan the call. FEATURES • A synced timeline for every city, color-coded by work hours, awake hours, and night • 7,000+ cities and every timezone, searchable offline — even by abbreviation like EST or CET • Tap the timeline to plan a meeting, drag either edge to adjust it, and share by email, calendar, or message • Groups for teams, family, or clients, with custom labels for each person • Automatic daylight saving handling • Light and dark themes, 12- or 24-hour time Your cities and groups stay on your iPhone, and every timezone lookup works offline. No tracking of you across other companies' apps or websites, and nothing shared with data brokers. TELL ME WHAT TO BUILD See something in another world clock that you wish this one had? Email mark@vibecode.review. I read every message and I build what people actually ask for — that is how most of this app got here. I build these apps on my own, in retirement, as a way of giving back. No company, no investors, no marketing budget — what you pay goes purely into developing the next feature and the next app. You'll probably laugh at what I charge. Free to start, no commitment up front. Most apps want that decision before you've seen a screen, then quietly bill you. Not this one — nothing to remember to cancel. After 7 days of use it asks you to unlock it — one payment, and that's the last you'll hear of it. Still not sure? Extend another week, free — I'd rather you were genuinely happy with it before you pay. This app alone, or $5.99 for all 10 — full apps across different categories, each one built because someone asked, and your payment covers every new app you ask me to build too. Never a subscription — yours for good, updates included.

Verdict
The clearest difference is in-app purchases: Sphere Time at none against ZoneTime's 3. Sphere Time also leads on iOS requirement (9.3 vs 16.4). ZoneTime's advantage is update cadence (every 3 days vs every 5 weeks). On price, ads and device support there is nothing between them.
