SilverStrong is built for people over 50 who want to move well at home — without a gym, without a class, and without guessing whether any of it is working. START WITH A NUMBER, NOT A GUESS The Check is a five-minute test you do at home: how many times you can stand from a chair in 30 seconds, and how long you can hold four balance positions. Your result is scored against the published figures for your age and sex, so you know where you actually stand. A SESSION BUILT FOR TODAY Every session is assembled to the length you choose, from movements you can actually do — seated, holding on, or free-standing — and it leaves out anything that loads a joint you have told it is sore. IT LISTENS, AND IT CHANGES Rate the effort and any pain at the end, answer one question the next morning, and the plan moves. Two clean sessions and it steps up. Pain, or soreness that is worse the next day, and it eases back. The reason is written on the screen in plain words every time. THE THREE WEEKLY TARGETS Moving minutes, strength days and balance days, tracked separately against the World Health Organization's weekly numbers for adults. Balance is the one almost nobody counts. BUILT FOR THE EYES AND HANDS THAT WILL USE IT Large type, high contrast, generous buttons, spoken instructions so you can look away from the phone, and a light and a dark theme. It works on iPhone and iPad. FREE, AND IT STAYS FREE The Check and its score, a complete session every single day, the whole movement library, the three weekly targets and every safety behaviour are free — permanently. SILVERSTRONG PLUS (optional subscription) - Unlimited re-Checks, your trend line, and a projected date you reach the published average for your age - Sessions that step up on their own, plus 20 and 30 minute lengths - Your stiffness compared across session days and rest days - A printable session sheet and a summary page you can hand your doctor - Your full history $6.99 a month or $39.99 a year, after a 7-day free trial. Payment is charged to your Apple Account at confirmation. It renews automatically at the same price unless you turn off auto-renew at least 24 hours before the end of the period, and you can manage or cancel it any time in your Apple Account settings. SilverStrong is a wellness tool, not medical advice. If something hurts, changes, or worries you, talk to your doctor.

BoxFlow runs your shadow boxing rounds, paces your breathing in the rest, and gives you one thing to work on. Built for beginners who shadow box at home. Unlike boxing apps that claim to watch your form, it has no camera and no sensors, and it never watches you train. It counts what it called and records what you told it — and it says which is which on every screen. THE ROUND BoxFlow calls the tempo and the combinations, so it knows exactly how many punches it asked for. Work and rest are timed against the plan, and the bell is a full-screen colour change you cannot miss. THE SIXTH BREATH A one-minute rest paced at six breaths a minute is exactly six breaths. BoxFlow paces them, you tap the ring at the end of each exhale, and every confirmed breath prints a mark on the ring. Six a minute beat both box breathing and free breathing on heart rate and perceived effort in a randomised trial of exactly this rest interval. ONE CUE, CHOSEN BY YOU Coaches at a national championship averaged eight instructions a round. You get one, you pick it from three, and it is phrased as something to do out in the world rather than something to think about inside your body — the phrasing that measurably improves punch speed and force. THE LADDER Six rungs of round structure. You move up when your last three sessions say you are ready, not when the calendar says so. TECHNIQUE, WITH ITS SOURCE SHOWN Teaching points and common mistakes taken from the international amateur boxing coaching manual, plus a plain answer to the claims this sport repeats — box breathing, 10,000 hours, 300 reps a day, and apps that say they can measure your form. FREE, FOREVER The whole training loop: unlimited rounds, every ladder rung, the breath pacer, the daily cue, the full technique library, your streak, and your last 14 sessions. The timer is never paywalled. BOXFLOW PRO (optional subscription) Unlimited history, the breath and cue trends, effort-versus-output insights, unlimited custom combinations, and CSV export of your own log. - Monthly or annual, with a 7-day free trial - Payment is charged to your Apple ID at confirmation; auto-renews unless cancelled at least 24 hours before the period ends; manage or cancel in Settings BoxFlow is training practice, not medical advice.
