Interesting you bring this up, as I am working on an Android mobile wallet with the option for mobile mining (this sounds silly, but you'd be surprised how well a properly configured ARM CPU can hash cryptonight-lite.)
As of now, everyone in the Aeon community (mostly found on Aeon reddit page) is waiting for code rebase to be officially released (which will happen with a hard fork in the coming months.) DrParadox/fabio and their dev team has been working very hard on the Aeon rebase and they tell of great things to come. You can follow their progress on their Github repos.
Until the code rebase is forked into Aeon, I cannot finish my mobile wallet properly. The rebase will prune the blockchain and allow for aeond to run on devices with much less RAM (as it stands now, the entire Aeon blockchain is loaded into RAM with aeond/simplewallet.)
Aeon has web-based wallets now and it's easy to make an app utilizing the same principal (where I would host the aeond server and generate wallets for users of my app.) But this design is flawed, because you are forced to trust me (or whoever.) Eliminating the trust aspect is kind of the ultimate goal of cryptocurrencies (especially privacy-centric coins like Aeon/XMR.)
LMAO... I don't know if that was a joke or not, but it sure was funny!
As for mining profitability: it depends on if you're mining to hold the coin for long-term gains, or if you're mining to quickly sell the coin to cash out.
If you're looking to quickly cash out... I'd mine ETN. It's a total ICO pump and dump, get mining it and sell it fast before it's dead. None of the ETN miners give a shit about the coin lol. Oh and ETN's mobile mining app... that is a joke. It's hard enough to get cryptonight-lite optimized for ARM devices... regular cryptonight takes twice as much CPU cache.
Now if you're looking for a coin to mine and hold for long term gain, that's where Aeon comes in. Or Monero... but good luck with their difficulty levels.
