I've been working on Nomie for around 5 years. It started out as a vanilla JS app, then ported to Ionic 1/Cordova, then ported to Ionic 2/Cordova, then ported to React Native...
Nomie 4 is now a combination of all previous versions ported to SvelteJS - which I am absolutely loving.
Constantly worried about hackers... the "how i'm stealing your credit card data" post brought my level of stress to the max.
I don't think I'll ever stop tracking and continue to use Nomie. Since it's purely offline and device only, like Alien Blue it should keep chugging for a while.
Nomie let you track anything you wanted. You created different trackers like: Drank Coffee, Peed, Smoked Crack - you customized the inputs, then with a single tap could track your life away. Then you could see how the things you track affect one another.
I built Nomie (https://nomie.app) over the last 5 years, the data that people track with it IS INSANELY personal. So much that the stress wore me out and I ended up shutting it all down 2 months ago.
I'd love to sell it, but I'm too afraid of giving it to the wrong people. Every investor or potential buyer wanted Nomie for the users data, not because it was actually helping people - GTFO.
I've currently (slowly) migrating from Dropbox and BTSync to Syncthing. I'd say you might have a glitch in the matrix if BTSync is running that high without any active transfers.
Before you try to market this further, I'd recommend you start busting ass to get products in there. Nothing more depressing than a ecommerce ghost town.
I'm that guy and I always have my phone. But, I'd be willing to bet that from a standstill with nothing in our hands, I could write down a task to my Corbinizer faster than you can find the app, launch it, type it in and save.
I was excited about Siri as a final replacement for the Corbinizer, but even now I'd rather not scream my tasks at my phone during a meeting.
