LawnWriter turns your yard into a canvas and your mower into the pen. So put on your nicest sleeveless shirt and crank up your "writing" lawnmower! That baby is way more artistic than you give it credit for. It's easy-peasy: Step 1) Trace your property boundary on the map. Step 2) Create a design in our super unprecedented Design Editor. Step 3) You MOW that masterpiece! Your creation can be your neighbor's dog's name in giant letters, a lonely heart, an alien love proclamation, or anything else your HOA can survive. LawnWriter turns that design into a GPS route, and voilà! You follow real-time, turn-by-turn guidance on your device as you mow, and watch the design come to fruition in the grass, pass by pass. QUICK START 1. Find your writing lawnmower. Preferably one you own. 2. Mount your device somewhere you can see it. It could be a suction cup mount, a neck mount like my cool "influencer" nephew like literally wears, or maybe the cupholder. SKEETER SEZ: Bonus points for you DIYers! The more creative, the better! Share pics or it didn't happen! WHY THIS EXISTS We've all stood there staring at the yard thinking, "Wouldn't it be cool if..." (choose your own adventure): * ...I wrote "HAPPY BIRTHDAY, BABY JESUS" in my lawn? (Or "MERRY HOLIDAYS", of course) * ...Karen mowed "6 7" in her front yard? * ...I made a maze for the delivery guy to go through? BEST USE CASE: Everyone knows the aliens have been here since the '40s. The mothership called... mama needs a fancy new landing pad. Mowing in a straight line is hard enough. Mowing "I LOVE TACOS" in 16-foot letters is straight-up cray-cray. LawnWriter gives you a GPS breadcrumb trail, so your designs come out looking intentional instead of... special. SKEETER SEZ: Did you see those lame robot mowers down at the hardware depot? They just wander around like a catfish in a kiddie pool. WHO IT'S FOR Bored dads. Overachieving neighbors. Internet trolls. Your momma. Anyone who's ever looked at a lawnmower and thought "I'm gonna do great things! Hold my beer." No technical skills needed. All the cool kids are doing it. You should try it. Just once, come on. MOW SAFE Glance, don't stare. Keep your eyes on where you're going, keep your feet away from the blades, and leave them young'uns and mangy pets inside. Results may vary. Depending on your GPS accuracy, the moon, and the length of your grass, we guarantee your design will be 100% almost mostly legible. Not responsible for neighbors' opinions.

Verdict
The clearest difference is in-app purchases: SUPLA at none against LawnWriter's 1. SUPLA also leads on ratings volume (18 vs 2). LawnWriter's advantage is rating (5.0 vs 4.7) and update cadence (every 11 days vs every 3 weeks). On price, ads, monetization model and device support there is nothing between them.
