Probably worth linking here to Derek Sivers' post "Obvious To You, Amazing To Others": https://sivers.org/obvious

I've heard of your method before, but I first read it in Fast Company in a story called The Amazon Whisperer, and while it might seem obvious now, I thought it was amazing when I first read it: https://www.fastcompany.com/3021229/chaim-pikarski-the-amazo...

That article on FastCompany about the Amazon Whisperer is incredibly eye-opening. Thanks for linking

This technique also works for Wordpress plugins, and just about any other paid category with reviews.

You can go into wordpress.org, just take a look at the download numbers and it will tell you flat out like whether somebody’s downloads are increasing overtime or are they decreasing, when the last updates were, all that kind of information. And you can get a sense from that information alone as to whether or not it would be possible to put another plugin that offers similar functionality

You can also find WordPress plugins that have a good install base, but the author is looking for someone to adopt.

I adopted a refer spam blocker plugin (https://wordpress.org/plugins/block-referer-spam/), added some features for a paid version (https://www.blockreferspam.com/) and it's doing pretty well.

This is the only non-vague, useful comment to this thread so far. A specific tactic that can be practically applied.

Don't worry, I've thought about doing something similar - I'm sure others have too. Still not so many people doing it that your niche will dissappear.

Would be interesting if you would plug your app(s) though. Might boost your sales too :-)

It is a highly localized radio player. Reduced data usage seems to be highly demanded by customers and other app owners tell users it's impossible. But I know nothing is impossible :-)

I am currently experimenting with a streaming proxy that will channel data with 60-70% reduced quality (for customers who aren't audiophiles).

Like everything in engineering, I imagine it is a balancing act.

I'm often amazed how good enough downsampled 480p video can be (e.g. on YouTube). If you're solving a problem for people, +1 to you.

My apologies if you're already aware of this: there are cheap VPS providers with unlimited bandwidth, perfect for these "streaming middleman" type of audio/video applications.

How are you monetising it? Is it a paid app (upfront/in-app purchase)?

I opted for in-app because then I won't have to manage two releases on play store. (demo/free app and paid app)

How did you query such list?

crawled google play data earlier and filtered offline.

Thanks for the reply. Did you face any issues during crawling process like access restrictions. If you share your practice I will be appreciated.

My crawler is modified from https://github.com/KopLyf/GPlayCrawler. Crawled 100k+ apps without any access issue.

I just tested this with `apt install python-scrapy python-pymongo && scrapy crawl google`. It seems to download one by one.

Edit: Interesting, it also downloads comments in my locale. Google play seems to be responding according to my IP information.

Ad supported or paid?

Ads are awful. It is currently a one-time purchase. Edit: this is one more thing that others were doing wrong.

Edit: Google ads are inane in my localization. You mostly get adult lines and "you caught a virus" scams despite opting out. Google doesn't seem to do anything about it despite complaints. I get paid because I removed the ads (even from demo version) and I do it gladly. Good riddance.

Reminds me of the time an ad managed to somehow break out of its boundaries and present the user with a popup. It still amazes me, this was Google Adsense for Android, but I saw it with my own eyes. And guess who received the bad reviews..
