Find the perfect time to catchup across multiple time zones without the mind-bending math. Overlap is a smart world clock that helps you connect with people in different time zones. It makes it simple to see the time in multiple places at once, and its fun Overlap Graph is a unique visual way to quickly find convenient meeting times across the world. You can choose ‘available’ hours for each time zone. For example Dan in London might be available from 2pm to 5pm and Rashida in Sydney might be available from 7am to midday. Bring up the Overlap Graph and it will magically show you the most compatible times to schedule your catchup. Overlap also displays your calendar events, so you can always find a time that suits your schedule. Available on iPhone, iPad and Mac. • You can see multiple time zones in one beautiful UI • You can swipe left and right to quickly move through time. • You can customize 'availability' for each timezone - this could mean office hours for a meeting or simply when you're available for a group chat with your far-flung family -no more 'Sorry that's 3am for me!' • You can rename each time zone; for example, you might simply rename a time zone to say 'Grandma' or the name of a client you work with. Or perhaps your Grandma is your client, no judgement here. • You can hide time zones that you don’t need right now so it’s always easy to focus on what you need to know. • You can show your calendar events so you can always choose a time that fits your schedule. • Once you’ve chosen a great time its easy to share it via your favorite messaging app or create a calendar event. • Standby Mode is a Lock Screen feature that activates automatically when your iPhone is charging in landscape mode. The Overlap widget fully supports this mode!

Verdict
The clearest difference is price: Overlap at Free against KDM Inspector's $2.99. Overlap also leads on rating (4.8 vs 4.0) and update cadence (every 3 months vs every 38 months). KDM Inspector's advantage is review sentiment (100% vs 67%). On ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Overlap is free to download; KDM Inspector costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Overlap holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Overlap has 875 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of KDM Inspector's written reviews are positive against 67% of Overlap's, so the app with the better star average is not the one people write more warmly about.
KDM Inspector ships an update every 38 months, Overlap every 3 months. The most recent releases landed on October 15, 2026 and October 29, 2026 respectively.
