About

A CW practice game for the gaps between QSOs. Copy the Morse and burst the balloons before they pile up. Each level brings more balloons and a higher speed. Practise single characters, groups, English words or callsigns. Use TYPE to enter what you hear, or KEY to practise sending. The screen keyer has a straight key and iambic A/B paddles. Choose your starting level and try to beat your best score. Settings and personal bests stay on your device. Online leaderboards are optional: post a score under your callsign if you want to compare results. No rig or extra hardware needed. Practice works offline on iPhone and iPad. No account, ads, subscription or in-app purchases. Want to use your own paddle? Connect it through an optional OpenShack Box with compatible BLE or Network Box firmware. The Box is sold separately. USB serial is not supported on iOS. Sound uses media volume and plays in Silent Mode. Practice stops when you leave the app or lock the screen. Internet is needed for online scores, Network Box connections and help links. English interface. By DL2CC / OpenShack.Read more
