I've just started to work on a framework for my first iOS game and I was wondering if I should support GL ES 1 or not.

As I'm the only coder working on this project, I'm thinking to drop it and focus on a GL ES 2 renderer only, but I'm new to the iOS world and maybe I'm just understimating the issue.

Any suggestion?

I think the number of devices left in circulation that only support ES1 is dwindling into the single digit percentages. I *think* the last time I saw numbers a few months ago it was like 5% or so, but don't quote me on that.

At this point I'd really say it comes down to what is easier for the project. If it's just a simple 2D project, ES 1 might be simpler, but otherwise go nuts.

Is that percentage because they are disappearing, or because the ES 2.0 devices are selling really well?

I'm guessing that they are being replaced by new ones. I think the stats I saw were from the Flurry analytics (or whatever it was before their merger) website, so it would based on the number of devices still in use.

Is it really that low? I'd be curious to see the distribution of devices still out there.

I'm going to transition to ES 2.0 this summer. I'm working on a pinball game in 1.1 now, so by the time I finish that and finish another game the iPhone 5 should start replacing alot of those 3G and 2nd gen iPod touches out there.

A friend of mine confirmed the numbers posted by Skorche and even if a GL ES 1 implementation would be easier, I decided to go for GL ES 2.

Thanks everybody for the replies

I looked on the Flurry blog and couldn't find any recent numbers, though not for lack of trying. They have a ton of statistics on there, but it isn't very well organized.
