A stage clock for iPhone, iPad, and Apple TV – synced across every display. Many teams start timer apps manually on multiple devices. The result: clocks drift apart. UbiStage Timer solves this. One device becomes the Control Console, all others sync automatically – virtually lag-free. Devices find each other automatically over local Wi-Fi. No setup, no pairing. Sign in once with a free account, then just open and go. One Control Console, multiple screens. Use iPhones and iPads simultaneously as stage clocks – all showing the same time. Syncing is fully local, no internet needed during the event. On the big screen, too: with UbiStage Timer on Apple TV, any large display or projector becomes a stage clock. Apple TV signs in without typing on the remote – it shows a code that you confirm here in the app under Profile → Sign in Apple TV. The automatic color change tells speakers how much time is left: the digits turn orange in the last minute and red when time is up. No need to read numbers – speakers can tell at a glance. The Control Console can also send short text messages directly to all displays – perfect for spontaneous corrections during the event. The connection holds up under pressure: if the Control Console briefly switches to another app, displays simply keep counting and find it again on their own. Ideal for conferences, stage productions, trade shows, and live events. Control Console free, unlock displays: • The Control Console on its own is free, with all features. • Basic: 1 display, monthly or yearly subscription. • Pro: up to 5 displays at once, monthly or yearly subscription. • Event Pass: up to 5 displays for 7 days, one-time purchase, no subscription. • Try Basic and Pro free for 7 days. The trial only starts when the first display connects. • The Control Console is unlocked; displays themselves don't need a purchase. Your purchase applies to your UbiStage account, on your other devices too. • If a subscription or Event Pass expires, connected displays keep running until the Control Console is restarted. Subscriptions renew automatically for the selected period unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID. You can manage and cancel subscriptions in your Apple ID settings. Cancel during the trial and you pay nothing.

Verdict
The clearest difference is price: UbiStage Timer at Free against OTAMap's $2.99. UbiStage Timer also leads on update cadence (every 4 days vs every 38 months). OTAMap's advantage is in-app purchases (none vs 5) and iOS requirement (15.0 vs 17.6). On ads and device support there is nothing between them.
