Kelva: Strength & Cycle

Strength training for women

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Kelva builds your training week and guides you through every session, set by set. Each of the 150 exercises shows an animated clay figure doing it. Kelva is a training app for women: a plan that stays put, and someone who guides you through every session, set by set. YOUR WEEK A few questions about your goal, your level, your training days and where you train: at the gym, at home with dumbbells, or with no equipment at all. From that Kelva builds your week out of a hand-curated exercise catalogue, with a glutes focus if you want one. After that it is yours: drag the blocks, move the days, put sessions together yourself. YOUR PLAN STAYS PUT Progress comes from consistency and progressive overload, not from a programme reshuffled every week. Kelva does not rebuild your plan behind your back. If a day does not suit you, tell Kelva and the session moves to your next training day. On a rest day you can bring the next session forward to today. Both apply to this week only. GUIDED THROUGH EVERY SESSION Before each exercise Kelva shows you how it is done. Then comes the set with its target, one tap on "Set done", and the rest counts down, as do holds and the warm-up. At the end you see how far your week has come. If you like, Kelva reminds you at the start time of every session, and the widget shows the next one with a countdown. 150 EXERCISES, EACH AS A CLIP Every exercise shows an animated clay figure doing it. With it: the instructions step by step, the muscles, the equipment, and where there is one, a substitute and an easier version. ASK KELVA Kelva sits in the bottom right corner. Tap a topic or type her a question: what today asks of you, how an exercise is done, what to do instead. When you say yes, she moves, shortens or swaps today's session. She also tells you what she does not say. No supplements, no diagnosis, nothing on pregnancy or menopause, no medication. If something hurts, she points you to someone who can judge it. ADD WHAT YOU NEED Training is always in. The rest you switch on or leave out: • Cooking and shopping: more than 680 dishes with recipes, matched to how you eat, planned as a week, with a shopping list • Calories: photograph your plate and Kelva estimates its calories and nutrients, measured against your daily target • Period: cycle day, estimated phase and next period, from what you enter or from Apple Health • Friends: someone in it with you ABOUT THE CYCLE, HONESTLY We do not tell you to train differently in a particular phase. The evidence does not support it: a 2023 systematic review found no influence of cycle phase on strength performance or on training adaptation. So your phase never changes your training. A FRIEND IN IT WITH YOU Link up with a code, a QR code or phone to phone. She sees how many sessions you completed each week, and your streak and training week only if you switch them on. Never your cycle, never what or how heavy you trained. YOUR CYCLE STAYS ON YOUR DEVICE Your cycle is stored and calculated on your iPhone, not sent to our server and not passed on: there simply is no endpoint for it. Kelva only ever reads your cycle, and we never write anything back to Apple Health. A question you type to Kelva and a photo you scan go through our server to an AI model, without your name and without your cycle, and are not stored by us. KELVA PLUS With Plus, Kelva changes today's session herself instead of asking first, if you allow her to. Along with your full history, your sessions in a calendar of their own, and meal scans without a limit (three without Plus). Kelva Plus is an auto-renewing subscription, monthly or yearly. It renews unless you turn it off in your App Store settings at least 24 hours before the period ends. Purchases can be restored in the app. Requires an iPhone on iOS 16.4 or later; the widget needs iOS 17. Privacy Policy and Terms of Use https://kelva.space/privacy https://kelva.space/terms

New: Kelva guides you through the session. Before each exercise she shows you how it is done, then come the set with its target, "Set done" and the rest with a countdown. Holds and the warm-up count down by themselves, and at the end you see your week. 150 exercises now show an animated clay figure doing them: in the exercise archive, in the session and while you train. A rest day? On the Today card you can bring the next session forward to today, and it then shows on its new day everywhere. If you allow notifications, Kelva reminds you at the start time of every session. The Today card shows the day's exercises, or that today is free and what comes next. If your glutes are what you want to work on most, your week now gets that focus. Calories and cooking are now separate: you switch each one on and off by itself. The daily check-in and the readiness number are gone. "I feel off" moves the session to your next training day. Fixed: on Sundays the kitchen shows the current week again, and a session ticked off in the chat now reaches your friend too.
