Your hormones affect everything — your mood, your energy, your strength. DROP IT is the first training app designed for women that auto-regulates your workouts based on your menstrual cycle and daily biofeedback. No rigid calendar rules. Just smart science that adapts to your body. Your body isn’t the same every day. Your training shouldn’t be either. DROP IT combines an elegant, minimalist cycle tracker with Siena, your personal AI-powered cycle and fitness coach. Together, they adjust workout intensity, volume, weights, and rest periods based on your cycle phase recovery thresholds and how you feel. No burnout. No plateaus. Just progress that flows with your life. What’s included: · Daily Biofeedback & Readiness Score Log your sleep, energy, mood, and localized muscle soreness to calculate your daily Readiness Score (0-100). The app calibrates hormonal overrides (like estrogen surges or active periods) to assess your Central Nervous System recovery accurately. · Adaptive Workout Recommended Sessions Receive a daily workout recommendation that automatically scales to your recovery state. The app applies scientific volume caps (limiting set volume to prevent fatigue), scales recommended loads using Reps-in-Reserve (RIR) safety buffers, and automatically adjusts rest timers. · Meet Siena: Your AI Cycle & Training Assistant Chat with Siena in a safe, private space to get instant, personalized guidance about your current phase, symptoms, and nutrition. Think of it as a context-aware health and training coach in your pocket. · Agentic Workout Generator & Customization Ask Siena to generate a complete workout template from scratch or modify your existing routines on the fly. Siena automatically scales sets, reps, and loads based on your cycle phase fatigue and recovery capacity. · Frictionless Workout Tracking Log your workouts with ease using our brand-new, distraction-free training interface. Access preview cards, a central workout hub, detailed set-by-set logging, and automated rest timers. · Personalized Workout Templates Create your own workout routines or use our phase-based templates. Build training plans that adapt to your cycle and save them for future use. Your cycle, respected: · MENSTRUAL: Manage active fatigue, track iron levels, and adapt load to symptom severity. · FOLLICULAR: Estrogen returns. High recovery capacity — time to build and increase volume. · OVULATORY: Peak force potential. Leverage strength with auto-regulated joint-safety checks. · LUTEAL: Manage systemic fatigue, increase rest intervals, and utilize adaptive volume caps. This isn’t just a gym app. It’s a new standard for women who train. Auto-regulated training has been shown to improve performance markers by up to 13.9% compared to traditional, rigid routines.

Kelva is a 64-day challenge built on a grid: your goal in the middle, eight life areas around it, eight small fields in each. Every day one new field opens. And your friends can see when your day is done. Pick a ready grid: • my best self • glow up • healthy body • calm mind • that girl routine • confidence Or build your own grid around your own goal. Keep our suggestions, swap single fields, or write every field yourself. YOUR DAY Each day your list on Home holds your open fields, your training or some movement, and a progress photo. Tick it all off and today's field lights up on your grid. After eight days a life area is full and the next one begins. YOUR FRIENDS Invite friends with a link. Round circles at the top show whose day is done. Friends see your day and your progress, never your words, your goal or your cycle. ALSO IN KELVA • A contract with yourself, signed with your finger on day one • Progress photos that stay on your phone • On your period or a sick day, a lighter list still counts the day • Reminders, so no day slips by • Missed a day? You can still tick off yesterday until noon. After that you start again at day 1, and your grid stays. • Share your grid as a sticker for your story, with or without the words • Your grid as a widget on your Home Screen • Your weekly training plan, guided sessions and the kitchen are still there if you want them • If you allow it, Kelva reads your cycle from Apple Health. It never writes anything to Apple Health. KELVA PLUS Kelva is free to download, and ticking off your days is free.
