I honestly wouldn't recommend using your cell phone to track your grow. Especially in states that they have passed laws that police can scan your phone in the event you are pulled over and detained or arrested. I believe Michigan is one of these states...so lets say you get pulled over and arrested or detained for something stupid (non mmj related).... In those states where its legal to scan your phone, now everything on your phone can be used against you... I mean its a worst case scenerio type thing, but hey, the less you have on you the better, and that doesn't apply for drugs, but anything, including incriminating data. Even though we are supposed to have legal medical weed, doesn't always mean that the local authorities recognize these laws, or understand them so I would advise against using any growing aps that "track, take photos, live stream monitor" or anything like that...... especially if you have an android phone linked to a google account, google tracks everything you search for on the web through your phone, and you never know who made the app and what exactly they have access to. I know my android, even without GPS on, can locate me within a few hundred feet... would hate for the wrong people to track your grow location...
