I'm assuming your tablet runs on Android then? If it's iOS then this list may suit your needs, it's the one I spoke of in my earlier post. My problem is that most of those, if not all (I can't remember now), are not Android.

I'm really surprised that I can't find anything decent like this.

I am not sure if you tried this app but I have the Burpee app on my tablet...I do not think it does everything but it is a great app to have...also Farmer's Almanac/Mother Earth News might have what you are looking for....

I don't have an answer. Just marking my spot so I can follow this discussion. I would love such an Android app, too. Preferably something that also has a web interface that syncs between phone, tablet and laptop.

This app looks promising, it might not have all the features you want. but it seems like it's on the right track. Let me know if it works out!

I'm running into the exact same problem and was strongly considering developing my own just because it's something I'd use (can't find a single one that does plant placement, for example). What do you mean by "photo logging" out of curiosity?

I am working on a project like that at the moment it's so exciting

Grow veg is not on android yet but will be worth the wait. It has drag And drop planting, calendar, reminder notification, tips

Tended App is an option that works on phones, tablets, and desktops and does about half of what you're looking for: https://www.tendedapp.com It lets you visually design a garden (including across different seasons, so you could keep track for crop rotation purposes), track your inputs and outputs, and see reports about your growing. There's also basic task management on a calendar view, the ability to upload photos, and it lets you see other gardeners' layouts as well. Check it out!

I found the following and seems pretty nice. Of course does not have all the features that you have asked... but it has notifications!!! :-)

It's nice to have the application that reminds
about watering the plants. On android I have installed "Lucky Plants:
Watering manager" download Lucky Plants
So now I'm happy and don't forget about watering
my flowers)

I am the creator of www.planmy.garden. It doesn't solve all of your requests, but it does give you #2, 3, 4, 5 & 6. #8 is coming and you can record as many photos as you like. It is web-based and designed for mobile so will work just fine on Android. Feel free to try it out and let me know what you think.

Just use acmarket apk

This is a great application I downloaded it at https://androidrub.com, thank you.

'Garden Manager' is a pretty good app and can be used for most of the things that you require.

Although some features are paid, I think is absolutely worth the money.
