A strength training–focused interval timer and automatic set counter built by a lifter with 25+ years of training experience. Designed to solve real “in-gym problems” such as forgetting timers, losing track of sets, and getting distracted during rest. It’s simple, fast, and reliable—so you can focus on lifting, not your phone. --- ◆ FEATURES ■ One-tap to start an interval No menus, no clutter. Works even when your brain is fried after a heavy set. ■ Automatic set counting Stopping the timer = finishing a set. Never lose track again. ■ Full background support Watch form videos, scroll, or text between sets. The timer keeps running and notifies you when it’s done. ■ "Did you forget to start the timer?" alerts If inactive for a while, the app reminds you to start your next set. ■ Simple, bold UI Big buttons. High contrast. Zero chance of hitting the wrong thing with sweaty hands. ■ Light and dark mode Easy on the eyes—even in dim, hardcore gyms. --- ◆ WHY THIS APP EXISTS When training hard, we all deal with: • Forgetting to start the timer • Forgetting which set we're on • Checking videos or notes during rest It’s a universal lifter problem. This app was built to remove those frustrations, so you can train harder, smarter, and with more intent. For anyone who loves lifting, and wants a clean, reliable tool—not an overcomplicated fitness tracker. May your training be efficient, consistent, and fun. --- ◆ TERMS OF USE (EULA) Please review the terms at: https://morimori-labo.monster/privacy_apps/intervaltimerplus_terms.html
