I am new to the hobby and have looked at the various apps that already exist for android. For the most part, the only feature I find useful of the existing android apps is battery logging and even at that it leaves much to be desired. To me, it seems like the writers of these apps are writing it for themselves and not a total noob who may need step-by-step help (this is especially true for the apps that calculate prop, motor, and ESC sizes).
So, with that in mind, here are my thoughts on the features mentioned above:
Various calculator tools for electronics (KV, voltage, etc.)
YES Please. But be sure to go step-by-step. Right now, I am thinking if I ever need such a tool, I will use MotoCalc as it seems the most helpful and easy to use. I would consider using a mobile phone app for this as well if it used a wizard similar to the one described in
MotoCalc's Tutorial.
Battery logging. Track the age and condition of your batteries
The apps I see for this have the bare minimum of functionality (I currently use
RC Battery Watcher). Ideally, I like it to also include a way to enter in how much charge I put into the batteries so that it can recommend what my future flight time should be. It would also be nice it it could track internal resistance measurements (assuming you have something to take that measurement).
Hanger Keep records of your planes (component list, parts sources, links, photos, notes, trim settings etc..)
I am not sure how useful this would be (but that may be because I currently only have 1 plane). But I can see it being helpful if it was tied to the electronics tool calculator, specifically, take the output of the calculator to generate a parts list of what to buy for a new plane and automatically add it to the hanger.
Flight log (Model flown, date, weather, location, flight time, notes, photos)
I see this as more of an additional feature of the battery logging. And, as stated above, add mAh that was put back into the battery after the flight and other battery relevant data for figuring out optimal flight times (like the style of flying and average throttle position).
Direct weather import in flight log
If you have easy access to the data, why not but that may be a lot more difficult to get the data than you might think.
Flight location database and weather
It would be nice to have the ability to get weather of the flight field before you leave to head there. Really, this is kind of a prerequisite of "Direct weather import in flight log". Without this, you do not have anything to import into the flight log so might as well make it possible to look at it from home so that users can know if it is even worth going to the field to fly.
Event calendar (what shows, fly-ins, etc. are happening)
This should be GPS based so I know what events are close to me and can filter out those that are farther than I am willing to travel.
Basics library (Glossary of terms, basics of flight, tips)
YES Please. Make it where I can access it directly was well as putting links in other parts of the app to get at the library to better understand what that part of the app s asking for or what the term the app is using means. Also have likes to YouTube videos that might help better understand terms.
RSS feeds from various hobby sites and Recommended YouTube channels
I am not sure if full RSS functionality would be useful. I like the idea of it recommending RSS feeds but I would want to use a RSS reader I already have for other things. But do make copy & paste into my reader of choice as easy as possible. Same thing applies to YouTube.
Social media support (Tweet, Facebook post info from your flight log)
Not sure how useful this will be but if the platform already supports something like this without writing your own Twitter reader (or other social media of choice), it could be nice. But I would not speed too much time on this feature. I'd even go so far as to say this can be a V1.1 feature.
Dopler speed
How accurate is this type of feature? I think this is more of a gimmick than something that would actually be useful to users but I'm a noob and can be wrong.
I hope my additional details help. Also, I know this is for an iPhone app but I would like to have it for Android. I would be willing to help with development to make it easier to port to Android.
