I hate subscriptions because, as @TheRealDunkirk said in another comment, things start adding up quick and quite expensive. For most people's personal lives, content like video (TV shows, movies) are more important than other kinds of subscriptions, like an app for productivity or workout or anything else. So that's where most of the money tends to flow (wherever people are willing to pay).

If you've been following the standard "sell and charge for upgrade once every few years" model, expect a backlash from loyal users when you move to subscriptions. It's quite simple to get this if you put yourself in the user's shoes and look at things. Wouldn't you feel ripped off or locked in by a subscription? Would you prefer some app that stops working, just like utilities to (like water supply stops if you don't pay the bills)? Many companies who've been in the business still fail to understand this simple point (AgileBits is a good example I can think of in the recent times), but they also change their focus from long time/loyal users to new users who don't really care much about comparing things or using many features. They don't see losing long time/loyal users who complain about this switch as a loss (and probably see it as good riddance).

If you're really anxious to get subscriptions done to get a steadier stream of revenue, my recommendation would be to price the subscription very low and aim for a large number of subscribers or price it quite high and work to get just a low number of subscribers. Both have their pros and cons, but this depends on your product, how valuable it is for users (compared to competing apps), who it's intended for, etc. As a user, my preference, if I do want an app or something, is a very low priced subscription. Maybe a dollar a month or better, a few dollars a year would be better (don't laugh, there are apps and others doing exactly this).
