Interval Timer ~ HIIT & Tabata vs RoundRep

"The timer numbers are too small to see mid-workout." "I wish I could instantly know when my rest is over." — Sound familiar? This app is an interval timer designed for strength training and HIIT, delivering your workout status intuitively through color changes. The screen turns "Burning Coral" during exercise and "Calm Indigo" during rest — so even if your phone is across the room, a single glance at the color tells you exactly what to do next. ■ Intuitive Timer Experience Through Visual Cues Reading tiny numbers when you're pushing your limits is frustrating.
