Read full description

Wake to a sound worth waking for. Clarion is an alarm planner built around twelve crafted sound themes and a calm weekly schedule, so your mornings start with a tone you chose on purpose instead of the same harsh buzzer. Most alarm apps bury sound choice three menus deep. Clarion puts it first: every theme has a name, a character and a written description, and you can hear a preview tone before you commit. Then you assign it to the days it belongs to and see the whole week at a glance. WHAT YOU GET • Twelve sound themes, from Gong and Harp to Ocean, Forest, Thunderstorm and Choir, each with its own character and preview tone • Alarms with a label, a time and the exact weekdays they belong to, so weekday and weekend mornings can differ • A Schedule tab that lays out Monday to Sunday and shows which alarms land on which day • A next-alarm card with a live countdown, so you always know what is coming and when • One-tap on/off for every alarm, with disabled alarms dimmed and kept out of the way • A quiet charcoal-and-brass interface, comfortable to read at midnight or at first light PERFECT FOR • Early risers who want a softer tone than a default buzzer • Shift workers whose wake-up times change across the week • Anyone who plans mornings by the week rather than one night at a time • People who like calm, minimal tools with no clutter WHY NOT JUST USE THE BUILT-IN CLOCK? The built-in clock treats sound as an afterthought and shows alarms as a flat list. Clarion is built the other way round: pick the mood of your wake-up first, then place it on the days it belongs to, and review your entire week on one screen. PRIVATE BY DEFAULT Your alarms and choices stay on your device. Clarion has no account, no sign-up and no tracking, and preview tones are generated on the device, so nothing is sent anywhere. FULL ACCESS Clarion Premium unlocks the app: all twelve sound themes, unlimited alarms and labels, and the full weekly schedule. Choose a weekly subscription or a yearly subscription. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel them in your App Store account settings at any time. Download Clarion, pick the theme that fits your morning and set your first alarm for tomorrow.

About

Sunplot

Read full description

Every seed packet says "full sun" or "part shade". Almost nobody knows which one their own garden is. Sunplot answers it with a number. Stand where the bed is, hold the phone up, and trace the roofs and trees around you with a finger. Then it walks the whole day a minute at a time and counts only the light that actually reaches that spot. WHY THE ANSWER IS DIFFERENT Other sun apps show you where the sun is. That is the easy half. The half that decides the answer is what stands in the way — the fence, the garage, the lime tree next door. Sunplot measures that skyline with the camera and subtracts it. A bed under open sky and the same bed behind a two-storey terrace are not the same bed, and the number knows it. FREE • Today's hours of direct sun at a spot, and what that means: full sun, part sun, part shade, full shade • What will grow there — 42 plants sorted into will do well, will manage, and too much sun • The map: where the sun arrives from, where it leaves, and where it is right now, with a slider through the day • The sky view: the sun's path drawn over the camera, and the skyline tracing that makes the answer real ONE PAYMENT UNLOCKS • The whole year at a spot — when full sun starts and ends, and the weeks it gets none at all • As many spots as you like — the bed by the fence and the bed by the garage answer differently • Which is better? Every spot side by side, ranked • A word before the sun arrives, so a short winter afternoon is not missed • The home screen widget One payment. No subscription, nothing renews, nothing to cancel. HONEST ABOUT WHAT IT KNOWS The compass in a phone can be badly wrong, and most sun apps draw a confident line anyway. Sunplot says so on screen when it does not trust its own reading. Before you have traced anything it labels the figure as open sky — the most the spot could get — instead of pretending to know. It is a gardening and planning tool, not a survey instrument. Check anything expensive against a professional measurement. NOTHING LEAVES THE PHONE No account, no server, no analytics, no third-party code, and nothing to sign up for. Everything is worked out on the device and stays there. It works with no signal at all. GOOD FOR Vegetable beds, borders and allotments. Balconies and window boxes. Greenhouses and cold frames. Roof pitches for solar panels. Working out which corner will take a shade planting, and which window a houseplant will survive.
