Most productivity apps are filing cabinets. You open them, you type things in, you close them. Whether anything actually happens is entirely up to you. Sofya works the other way round. It reads what you have going on, and it gets in touch. A PLAN EVERY MORNING, FREE At 7am the Morning Planner looks at what is due today, what is already overdue, and the habits you are trying to keep. Then it tells you where to start. You do not open the app. You do not stare at a list deciding. It arrives. This is free, and it stays free. WHAT YOU KEEP IN IT Tasks with priorities, due dates, tags and subtasks. Type "gym tomorrow 7am" and Sofya offers you the due date. Habits, daily or weekly, with streaks that are worth protecting. Goals broken into milestones you can see yourself moving through. A focus timer that knows which task you are on, and counts the hours it saves up. Bringing a list over from Todoist or TickTick, so you do not start from an empty app. All of that is free too. SEVEN MORE AGENTS, IN PREMIUM The Pattern Spotter is the one nothing else can do. It reads your tasks, habits, goals and calendar together and tells you what they say as a group. Things like which day of the week your streak actually breaks on, or what a morning full of meetings costs the rest of your day. No other app holds both halves of that sentence. The Habit Coach checks in when a streak is about to break. It does not nag. It names the pattern and offers you a freeze. The Focus Guardian books your focus time on weekday mornings, before the day fills up. The Wellness Check notices when you have loaded more into a day than a day holds. The Smart Scheduler reads your deadlines and works backwards. The Goal Advisor asks you on Sunday for one thing to move this week, and Friday reports back on that exact thing. The Insight Narrator writes up what actually moved, from your real data. Not a chart to interpret. A paragraph to read, in the app and in your inbox. IT LEARNS WHEN YOU WORK After a few weeks Sofya knows the hours you actually finish things in, and moves your morning plan to suit. A 7am briefing is no use to someone who starts at eleven. ANSWERING BACK Log a habit or use a freeze straight from the notification, without opening the app. Ask any agent why it said something and get a straight answer about your own data. ALSO IN PREMIUM Apple Calendar sync, so due dates and focus blocks sit alongside your meetings. Streak freezes, for the days life gets in the way. Task breakdowns that turn something vague into the first three steps. The weekly write-up by email as well as by notification. ABOUT YOUR DATA Sign in with Apple is supported if you would rather not hand over an email address. Sofya asks for nothing it does not need, and you can delete your account and everything in it from Settings, at any time. SOFYA PREMIUM Available as a monthly or annual subscription. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple ID settings.

Turf/OS is a local-first lawn planner built for homeowners who want better timing, better records, and better decisions for every part of the yard. Instead of relying on generic seasonal calendars, Turf/OS uses your mapped property, your grass type, your USDA zone, and your local weather to tell you what to do next — and exactly when to do it. MAP THE LAWN THE APP WILL PLAN AROUND Draw your front, back, side, and garden zones. Each area tracks its own square footage, grass type, and treatment history. Multi-zone properties are first-class — not an afterthought. A SCHEDULE TUNED TO YOUR TURF Turf/OS builds a custom application calendar from your grass type (cool-season, warm-season, transition), your USDA zone, your local weather and soil temperature trends, and your recent treatment history. Pre-emergent windows, fertilization timing, weed pressure, and mowing height — all scheduled around what your lawn actually needs. HYPER-LOCAL WEATHER THAT DRIVES TIMING Turf/OS pulls live data from the National Weather Service and Open-Meteo: soil temperature, dew point, growing degree days, wind, Delta T, and ET. Spray windows, mowing guidance, and weekend planning all adapt to conditions at your curb — not the regional average. READ THE SOIL. GET A PLAN BACK. Drop in your soil-test numbers — pH, P, K, Mg, Ca, organic matter — and Turf/OS returns a personalized action plan: which products to apply, at what rate, and when. Recommendations are grounded in real agronomic guidance. SMART PRODUCT RECOMMENDATIONS FROM YOUR SHED Turf/OS recommends products from what's already on your shelf first, calibrated to your yard's needs this week. Scan barcodes or add custom products with your own rates and costs. Track what's left in the bag, what each application cost, and what worked. POWER FEATURES - GDD-based PGR tracking: Trinexapac re-application alerts based on heat accumulation - Spreader calibration: save your equipment settings once, get accurate rates every time - Treatment logs: product, rate, cost, weather, and zone all captured - Zone photo timelines: watch each area change through the season - Weekend Assistant: reminders that wait for the right application window - Local notifications for reminders and weather-related alerts LOCAL-FIRST BY DESIGN Your property maps, photos, treatment logs, and settings stay on your device. No account required. No cloud lock-in. Your data is yours. BUILT FOR REAL PROPERTIES - Multiple zones, mixed grass types, irrigated and non-irrigated areas - Cool-season and warm-season turf (Bermuda, Zoysia, Centipede, KBG, TTTF, and more) - USDA zones across the continental US - Property sizes from 1,000 sq ft to several acres - Treatment history that carries year over year WHY TURF/OS IS DIFFERENT Most lawn-care apps either dumb everything down to a generic monthly checklist or bury you in data nobody acts on. Turf/OS sits in the middle: serious agronomic logic translated into clear weekly decisions. Every recommendation ties back to your zones, your grass, and your weather. If you're tired of guessing whether this Saturday is right for pre-emergent — or whether soil temps are finally there for fert — Turf/OS gives you a defensible answer. Plan confidently. Track consistently. Make every application window count.
