SleepBlend is a sound console for bedtime. Instead of scrolling a wall of tracks at midnight, you compose tonight's blend from a handful of voices — rain, ocean, wind, coloured noise, a warm drone — each generated on your device in real time, with its own volume and its own place in the stereo field. Nothing to download, and no loop that comes round again at 3am. COMPOSE YOUR OWN SOUNDSCAPE Stack voices in the multi-layer mixer and hear the blend change as you move each slider. The Resonance Ring shows the mix as bands of light around a still centre — when the voices sit in balance it settles into an even halo. A SLEEP TIMER THAT FADES, NEVER STOPS DEAD Set a timer with quick presets and a gentle fade-out over the last few minutes, so the night ends softly instead of cutting to silence. A blend keeps playing with the screen locked. ONE HONEST NUMBER Give a one-minute check-in in the morning — how quickly you drifted off, how rested you feel — and the Sleep Mix Score reflects how each blend works for you. It is built only from your own check-ins, shown with a transparent five-part breakdown, and it stays quiet until there is enough of your own data to be honest. Nothing is measured: no sensors, no wearables, no microphone. IT LEARNS WHICH VOICES SUIT YOU Over time the app surfaces which sounds turn up on the nights you settled faster, labelled as a pattern in your own logs — an association, not a cause. Tonight's recommendation is ranked from the same data. Every one of these calculations runs on your device, from your own entries. FREE, AND GENUINELY USEFUL The whole play loop is free: the full mixer with per-voice volume and stereo balance, the core voices, the sleep timer and gentle fade, the morning check-in, your Nights Composed streak, a nightly wind-down reminder and a 7-night rest trend. Free keeps up to three saved blends — and a blend you have saved is always free to replay, edit, favourite and delete. SLEEPBLEND PRO (optional subscription) - All 50 premium voices, and the starter mixes built on them - Unlimited saved blends, and deeper blends of up to eight voices - Adaptive recommendations with tweak suggestions - The full Sleep Mix Score breakdown, 90-night trends and sound associations - Per-voice Adaptive Volume Fade, and Gentle Wake - Monthly or yearly, with a 7-day free trial - Payment is charged to your Apple ID at confirmation; the subscription auto-renews unless cancelled at least 24 hours before the end of the period; manage or cancel it in Settings SleepBlend is a wellness and relaxation tool. It is not a medical device, not a sleep tracker, and not a treatment for insomnia or any sleep disorder. If sleep trouble persists, please talk to a licensed healthcare provider.

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.
