A meal (burger, fries and a drink) in McDonalds will cost you at least $5~$9 depending on the size of the meal you get. Would you say that is expensive? Yet, when an app is anywhere from $2~$10, people will deem it as "expensive". It astounds me when people don't give a thought about spending $10 on food but when it comes to any software-related stuff, the same $10 is "too much".
I know exactly what I'm getting for $5 worth of McDonalds. $5 for an app feels more risky because I have no idea if there will be any value.
The difference between 99cents and a higher price making the same profit is a significant difference in number of sales. Maybe if they get featured it would be worth it to lower the price to ensure it stays in the charts, but if it's not ranked it does not make sense to have a lower price.
People say what they wish for and then do another thing. People complain about prices, and then buy anyway if the product is right for them. And if the product is exactly made for them they will sense the value and know that the price is great. $5.49 for something you will potentially use for years? I have no trouble seeing the value. Though I only use Android devices.
What I'm saying is the price is too expensive for me to get a large sample of my social group to try it out.
This will hinder the app's growth.
I have done pricing experiments. For apps which are not ranked, and have no ads driving extra traffic, 99cents vs even $6.99 usually equals the same number of sales. Lower prices don't matter as much as people think they do. When you talk about risk, do you mean that you do not believe your social circle will find this interesting enough to even know about it? If you did then price wouldn't matter... have you ever recommended anything higher than 99cents to anyone? That 99cents is a popular price for "apps" does not matter. Devs should still charge more when it makes sense to.
