Misleading
I don’t mind freemium apps, but if you’re going to put THE primary function of your app behind a paywall it’s dishonest to hide behind the freemium model, suggest being more transparent about this so potential users can avoid feeling like they have just downloaded bloatwear that serves no function. When you’re aiming to make your potential users pay to use the primary and most likely the only thing (look up numbers) they have downloaded your app for, be upfront about it.
