About this app

Perfect your swimming start with a practice tool built for real race conditions.

This App lets you set custom timing for "the long whistle", "Take your marks," and the "starting signal", then repeat your start until it becomes automatic. Turn on random start timing to train for the unpredictability of an actual meet.

■FEATURES
• Custom whistle, marks & start signal timing, adjustable to the second
• Random start timing for realistic race-day practice
• 3 presets to switch between training setups instantly
• Dark mode, easy on the eyes for early-morning practice
• Flash alerts as a visual start cue

Built for competitive swimmers, coaches, and swim teams who want faster reactions off the blocks. Every session with this app is race-ready practice.
