For me at least.
I'm Scottish, which means I don't spend money unless I have to. When I was younger I used to stretch my bus passes out well past their expiry date because I knew the drivers never really bothered to check the expiry date as it was in tiny little writing. Each time I got caught I'd just say "Oh sorry about that, I must have picked up an old one, here let me pay the fare" I'd always by a new one before my next journey. The shortest time I ever managed was 8 days (probably about 20 journeys).
I don't steal apps. I don't pirate them either. But I will certainly try and get them for free or use them for free for as long as possible. Marco Arment actually made a good point in this weeks ATP where he said, and I'm paraphrasing here "If you give users a free option they will adjust their habits to stay in the free option". I'm definitely one of those people.
I visit app price websites daily. If an app is free that was previously paid, I'll 'buy' it in the knowledge that it will likely go back to being paid and I'll get the future updates for free. I probably only use 30 apps but I've got over 1000 in my purchased tab in the iOS app store.
Here's some examples of apps and services I use because they don't cost me anything.
Apples stock apps - Weather, Email, Notes, Calendar, Reminders, Voice Memos because they only need one login to setup and they are free and cover multiple usage cases. I know they are decent and aren't likely to go anywhere any time soon.
No RSS Apps. I was using Feedly for a brief period but stopped as RSS was just another unread list to work through. I haven't missed it at all.
Simplenote - I use this for syncing work stuff and articles for this site. There's an app on iOS and on Mac so why pay for something like Byword?
Twitter - I own Tweetbot but would probably avoid buying it now if I didn't already own it. I prefer the official client for its functionality.
Google Drive - I get 15gb of free storage but I have a lot more than that after getting a couple of review units. (Pro-tip: If you buy one and return it, they let you keep the storage too).
Dropbox - I use this for syncing some text files and settings for apps that support it. I have 8gb there I got just by installing things like Mailbox, Carousel, tweeting about it etc.
Day One - This was free recently but I got it in a freebie deal about a year ago. I didn't really use it much but I have started using it a lot more in the last couple of weeks.
Dark Sky - I got this for free using the Starbucks app. I already had a US iTunes account so that wasn't a problem. I just have to remember to install it whenever I get a new device as it's on a different account
Instapaper - I mostly use Reading List but I got this in the same scenario as Dark Sky above. Pocket is free and I'd use that if I had to pay for Instapaper. Instapaper has better parsing, better pagination, better dark mode and superior typography options though.
Evernote - I actually use this for storing clipped articles I have published elsewhere online or when someone links to me. This never goes over the free 60mb. I also store PDF's exported from Safari in Google Drive.
Instacast for Mac - I bought the iOS version but thought the Mac version was way to expensive. So I just redownloaded the trial every month and signed up with a different email address each time. I've now switched to Downcast because Vemedio seem to come up with a new way to extract money every so often. Downcast is ugly but it works and I paid for it.
I'm not against spending money on things entirely. I like the idea of paying for apps and supporting developers. I just always default to supporting my own family first. I keep my phone in a case because I don't want to pay to replace it if it breaks.
Here's a list of things I pay/paid for
Netflix - Because it's worth it for House of Cards, Breaking Bad and Orange is the New Black on it's own.
Squarespace - The all in one solution for creating an online portfolio...just kidding. I don't use them because they are a sponsor I use them because I honestly think they are great. I also have piece of mind that they have really good podcast support if I ever decide to do yet another one. (Because I damn sure am not going on a network again, I can still smell the burning flesh from my fingers from the last time I did that)
Downcast - See Instacast above
Spotify - I like the unlimited nature of it. It also means my son can listen to any song he wants and I don't have to pay for it.
iTunes TV Shows - There's a catch here. I buy them in the US store where I can because it works out cheaper and most shows air there first. (Pro-tip #2: A lot of new shows will give you the pilot episode for free)
All these little purchases mount up. If I started buying lots of apps just to try them and paying for things like app.net, droplr, Dropbox, Tonx, Amazon Prime, Comixology then before you know it I'd paying potentially 100's of dollars a month. I'll try stuff if it's free but I tend to stick with what I know because it's already free.
I'm not entirely sure what the reaction to this article will be. I expect it'll probably be evenly split between people agreeing with me and people who think I'm a tightfisted bastard. People might even say "That App only costs the price of a Starbucks". I hate that. I don't drink at Starbucks because it's overpriced so that analogy doesn't work on me.
It used to be that prevailing opinion was that a paid app was likely to disappear but that's not the case anymore. Paid apps aren't any more or less likely to be sold than free ones but the paid ones sting more when they get killed off. Sparrow is a good example of this. Everpix died too.
So for me, personally, I'm not surprised about the talk of App developers not making as much money. I'm not helping. I can't see either changing any time soon.
