As I have mentioned before, we have begun work on an Android version of powerOne calculator. Over the past few years we have accumulated a list of about 375 people who emailed us requesting an Android version of the app. To help get a feel for what is out there we conducted a brief survey. The response was incredible, over 50% response rate.
Two questions, I think, are most pertinent for sharing: 1) What device are you using; and 2) What operating system version does it run? Obviously this is a very small sample of people who were self-selected and are primarily in the United States. This data may not match the Android market at large.
The devices were scattered all over the place. The average per person was 1.2 devices per person, which means that one out of five responders had two devices. The most popular device series in use was the Samsung Galaxy S series, followed by a wide margin by the Motorola Droid devices and HTC Evo series. Of the tablets the Asus Transformer was the most owned followed by the Kindle Fire. Not surprising at all. There were a few votes for the Nexus 7 and a few more that said they would buy one in the future. Here’s the breakdown:
Other is just slightly a smaller pool than Samsung Galaxy S, an amazing array of devices.
Luckily the operating systems were much more straight forward. There were two primary OS versions: 2.3 and 4.0. Apparently a few vendors are releasing 4.0 or 4.1 operating system updates as a number of customers mentioned that they were updating their OS version soon. Personally, I was pleasantly surprised by the uptake of Android OS 4.0. Based on all the public data I’d seen it looked like 2.3 was very dominant and 4.0 had little uptake. At least this group is reporting differently.
powerOne is the kind of app that cares less about the device and more about the screen size and OS version. powerOne doesn’t have streaming needs or heavy networking needs so we generally don’t have to worry about minute changes between devices. This is why I care more about the OS version data here than the device data above.
What We Have
Since I shared what this self-selected group has, I would be happy to share what we have here, too. We have three devices: a Samsung Galaxy Tab 10.1, a Samsung Galaxy SII and a Nexus 7. The development is being performed by a partner and they have a plethora (I love that word!) of additional devices. The OS version is 4.0, 2.3 and 4.1, respectively.
As mentioned above device and OS were the two primary questions. We asked two others. The first is does your device have a hardware keyboard? About 10% of devices did. The second was more pertinent to powerOne: do you use RPN input mode? There were three possible responses: not important, prefer it but can live without it, and it’s a requirement for me to buy. 23% said it was a requirement. 48% said it was a requirement or preferred. I have no doubt that this is very high for the calculator population as a whole but the HP12c had a huge influence on the financial calculator market specifically. I’m sure many in this self-selected group were heavy 12c users before our software and the PalmPilot came out.
