Although I think an app as important as this one should be free, or a one-time buy, it never stops amazing me how good it is. In this time of fake news, internet access by social media is misused by absolute dimwits, robots, and governments alike, it's a breath of fresh air to read the stories published on the Medium platform.
The only reason I withhold the fifth star is the business model: it's quite an expensive way to get the top stories only for a high weekly fee. I know there are other options, but I can't afford a yearly membership, and quite frankly there are weeks I forget to read even one story.
Therefore I strongly urge the makers of this very important app to consider a one-time buy: if that was an option, no matter how high the pricing for it would be, I would be more inclined to pay than my on-and-off membership fee as it is now.
