It will get you started but lacks the depth to be useful. It looks pretty but I'm deleting it because it just is not what will work for my zoysia yard. ;( ### 1/5 — Not worth a dime *2015-05-20, version 1.4* A complete rip off. I learnt nothing new from this app... Absolutely nothing ! ### 5/5 — (Updated: Back to normal). Once a great app *2015-04-11, version 1.4* (Now with the update the app is back to working and still a wonderful app for all gras types and a great resource of compiled knowledge.). This was once a wonderful, no-nonsense app that really helped with growing a great lawn. It just doesn't seem to work with iOS 7 or greater. ### 1/5 — Not working *2015-03-18, version 1.3* Do not buy it ### 1/5 — Not working *2014-12-03, version 1.3* I should listened to the last review. I reinstalled the app repeatedly & all I get is the home screen saying it's loading & this is on a new iPhone 6. ### 1/5 — Grass master *2011-12-05, version 1.3* Junk!!! You can find a lot more staff for free. ### 1/5 — Not worth $2 *2011-03-07, version 1.2* Has no info on over seeding and when to do it. Not worth $2, should be free! ### 5/5 — Well Worth It *2011-03-01, version 1.1* Great app with good UI ### 1/5 — Grass master *2011-02-22, version 1.1* Junk.can get this info for free anywhere.It's a very small program and really is garbage! ### 5/5 — Excellent app for $2.00 *2010-10-16, version 0* I don't agree with El Paso. This is an excellent app and very informative. Covers everything the average homeowner needs and then some. I work with a Master Gardener and this person gave the app a big thumbs up after looking it over. It's definately in line with Extension Offices and University info regarding lawn care. I checked this out for our lawn type and this app was right on the money. The scheduling process worked flawlessly and synced up to Outlook without a hitch. The included photos of the diseases are excellent for identifying problems quickly. Yeah you can google up the diseases on your computer but I like the ability to stand on my lawn with my iPhone, open the app and instantly identify a problem and instantly know what to do about it. That's pretty neat. For $2, it's well worth it. ## Frequently asked questions about GrassMaster ### What is GrassMaster?
