Tap "Continue as guest" and go straight to setting up a lawn. Add an account whenever you like and everything comes with you — zones, settings, watering history. REDEEM A CODE Got a promo code for Pro? Settings → Redeem a Code, without hunting through the App Store. ALSO The version number now sits at the bottom of Settings — tap to copy it. If you ever report a bug, that one line tells me more than you'd think. ### 1.6.3 — 2026-08-04 Fixes evening reminders on iPhone. Notifications now arrive as expected — just update. ### 1.6.0 — 2026-08-03 FIXED: EVENING REMINDERS If your daily watering reminder stopped arriving — or never started — this update fixes it. Some devices failed to finish registering for notifications, so the evening heads-up had nowhere to go. Nothing to do on your end; just update. You can confirm under Settings → Notification Preferences. A NEW SETUP Setting up a lawn is now one question per screen, in plain language, with an explanation of why each answer matters. Grass type, soil, and shade are tappable cards instead of dropdowns. TWO LAWNS, TWO ANSWERS Setup now offers to add a second zone at the end. Front and back yards dry out differently, and each zone gets its own daily answer. SPRINKLER TIMING, WHEN IT'S USEFUL We stopped asking how many minutes your sprinklers take to put down an inch before you'd ever used the app — nobody knows that without going outside with a tuna can. Lawn Logic now asks once you've logged a watering session, and walks you through measuring it. ### 1.5.0 — 2026-07-22 A redesigned home screen, and a smarter model underneath. YOUR LAWN AT A GLANCE The daily answer now leads with a soil moisture arc — one number, one word, and a plain sentence telling you why. Today's heat warning and the best time to run your sprinklers moved into that same card instead of sitting around it. The arc is not a score. Letting your soil ride down toward its trigger is what drives roots deeper, so a lower number is often the app working correctly. MY LAWN / DETAILS The app is now split in two. My Lawn answers one question: water today or not. Details holds the 14-day moisture trend, the full forecast, and every number behind the recommendation. DORMANCY DETECTION When sustained cold puts your grass to sleep, Lawn Logic now recognizes it and stops calling for water. Dormant grass can't use water, and watering it anyway invites disease. The home screen shifts to winter straw so you can see that the app knows. SOUTHERN HEMISPHERE FIX Seasons were running six months out of phase below the equator — a lawn in Australia in January was being treated as though it were mid-winter. Corrected in the app and in the evening forecast check. ALSO - Smoother seasonal transitions instead of month-to-month jumps - "Losing per day" now reads the same number everywhere in the app - Clearer, less jargon-heavy wording throughout the recommendations ### 1.3.0 — 2026-07-19 • Sage takes action — tell your AI lawn coach "my mowing day changed to Friday," "that storm missed us," or "we're on vacation until the 28th," and confirm the change with one tap • Rain corrections for everyone — tap the Rain card to record what actually fell at your lawn (free feature!) • 7-day free trial on Pro Annual • A fresh, cleaner look throughout the app • Fixed overlapping labels on the moisture trend chart ## Related topics [lawn water](https://appshunter.io/ios/topics/lawn-water) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
