Seriously if you cannot see the usefulness of the kind of apps that Ponury makes then you really should have just bought an iPhone and enjoyed la-la land with the rest of the apple users. The prices asked from Ponury for apps like this are absolutely nothing considering the huge amount of time that he takes out of his personal life and work to develop these things for people that he doesn't even know. It's thanks to guys like him that Android holds a place beside other platforms and continues to provide a good alternative to other platforms.
At the moment Wifikill and Faceniff are (as far as I know) both $5... I am sure there are at least 100 more useless things that you would have spent your money on in the past... I make $5 in about 5 minutes worth of work.. is that really that much to ask from YOUR time, considering the amount of time he spends on writing and maintaining these apps?
Consider what you are buying...
1. Apps that are both intuitive and work well, and provide you features right in the palm of your hand that you had probably never thought possible.
2. Continued support and updates in the future, where applicable.
3. Putting something positive and constructive into something that is awesome and helpful.
Donating is a fair choice for an app this good. If you don't want to donate you can use the trial versions that have ads and/or time/usage limits. You're already given the option to try the apps out to see that they work and what they are capable of. It's not like you're having a blindfold tied around your head and you're forced to make a decision based on nothing.
The fact that most devs who make silly mobile games, and then charge for items and etc. in-game which can run a person easily over $20, and Ponury is asking for pretty much what a packet of smokes costs in the EU, or a good coffee from an expensive store is nothing.
I bought Faceniff 3 times and Wifi-Kill 1 time. Once for my phone on the old version. Once for my phone on the new version and once for my wife's phone on the new version. Even though she will never use it.
As someone who is trying to develop his own apps as well, I can only imagine how hard it must be to write something that has practically never been done before from the ground up.
For that, I am more than happy to buy the man a couple of beers. If anything it helps me sleep at night. I will never understand how people, after buying a 500€ phone, are so hesitant to spend $5 on something they get to keep forever...
I don't want these apps combined, and I doubt that it has anything to do with donations or pricing issues, simply because I want 2 separate apps for 2 separate things. There is absolutely no rationale upside to combining them, or downside to having them separate. If anything I know better when one has been updated and the other hasn't. It lets me progressively track updates and features.
