I always thought it was insane that any app could just listen to everything that went to the clipboard, even while in the background and without any permission. I'm sure many people copy passwords, credit card numbers, bitcoin private keys, etc.
Personally, I always use the same app when sharing URLs (Send to Instapaper). Yet, it always shows me default actions I never used (send via Twitter DM, Print, etc.) and takes like 5 seconds to have the UI usable.
The user can always refuse access to SMS, contacts and other sensitive features on Android.
I have Messenger on my Pixel, it's working fine without having access to all of that.
I'm a heavy Instapaper user myself and was always disappointed with the quality of the official Android app: it runs terribly slow, some articles don't even show up, no image thumbnail, etc.
My app doesn't have all the feature from the official app yet (I'm starting simple), but I'm very open to feedback.
From the article:
"Unless you know the exact name of my app, you won't find it."
His "Website constructor" app is in 3rd position when I search for "Website". Not that bad for such a generic keyword.
Also, I guess one thing with these apps is that the price range (between $12 and $20) is a quite high compared to the majority of the other apps on the store and (unfortunately?) a lot of people are not ready to buy apps >$2.
I guess that the store search algorithm depends on the conversion rate (people buying the app VS people trying it) and that conversion rate is probably pretty low, so maybe lowering the app price could lead to more sales and higher ranking.
