martinadamek··on Show HN: A different kind of coloring book for kids (Android). Simple and clean.
It's coming ;-)

I did all the graphics, programming, etc. My wife (she is children book illustrator) created the animals set and will create more. Others are licensed from other profesional illustrators from stock sites.

From experience with my son (now 4y old) I think it's about 2 years. But if parent will assist, kids learn quickly :-)

I tried dozens of them on Android. They are so busy, terrible UIs, ugly pictures, ads... so that's where I want to fight - with a nice thing. Thanks a lot for tips on apps, I'll check them out.

I tested mainly on my 4y old son and then asked few friends to test on their kids. No problems reported. Re HW button - I am thinking about design without it especially because I am going to build iOS version that doesn't have one.

Exactly. I hope that current model (get for free and pay once to get everything forever) will make happy both sides :-)

For now I have tried to solve it by removing all BUY buttons from the interface but one - on welcome screen, that buys you everything forever - which is effectively turning app into 'pro' version without ads, offers, just pure content. IAP is new to me, but from what I read it is the most effective way to monetize. Needs to be done nicely, though.

That is actually really good idea with the update. Thanks!

Thank you for the feedback, I really appreciate it!

I've already played with that, but it had bad side effect on something (I can't remember what exactly that was). I am going back to that in next updates.

There is of course short time between taps which if exceeded, then the tap counts is reset. I'll think about another unlock, I'll just collect the feedback and decide. I've got some feedback on overlaying strokes, so I'll think about it for sure. Thanks for the tips!

UPDATE: All BUY and RATE buttons were removed from all sets. Only all-in-one unlock is available in welcome screen and it enables everything forever. I want you and your kids to be happy. Enjoy! New version 1.0.2 should appear on Play Store in moments.

At this point I must say that Android is awesome in a way I am able to provide quick updates. Love it!

Thanks for all the feedback guys! App like this should never replace real thing! My wife is children book illustrator (and created the first set with animals) and she draws with our son on paper a lot. This app can help you in certains situations, where you need to entertain your kid for a while and phone is the thing you always have. I am also getting mixed feedback about buy buttons, so I will experiment tonight and will bring better solution which will be even less annoying. If you have good examples or suggestions, I'll be happy to see them!

Thanks again.

This my new Android app. I really tried to make it simple, beautiful and not annoy the kids and their parents with ads. Though I am not sure what is the best strategy to add in-app purchasing and still be nice to users.
martinadamek··on Standing Up For Android
I am in for the challenge! https://market.android.com/details?id=com.codecarpet.reading...
martinadamek··on My Android app (1.6M dloads, 4.5 rating) was suspended from Market
[update] I have the app available back in my hands, but unpublished. I am not going to put it back right away, because of all your feedback. Thank you all for the opinions, I've got my lesson.

AFAIK ads are served between 9AM-9PM. But to be honest, after reading all the feedback and seeing all the other opinions, I am not as confident as I was before. Now I'll need to manage this situation reasonably.

I also think that it might be this one.

Actually, this is one valid point against these ads, that I could agree with. I guess this must be solvable.

Doing this on every action is too much I think, this leads really to uninstall or buy.

Yes, they did. But I didn't mind, they've used that for good apps. But one smartass didn't even bother to change the icon!

Sample diffs are going live this week, too.
martinadamek··on The Startup Story – From an Idea to Our First Customer in 7 Days
Yes, I would pay for this.
martinadamek··on The Startup Story – From an Idea to Our First Customer in 7 Days
I know exactly what you're talking about. I am happy about any non-positive feedback, because I want to keep contact with reality.
martinadamek··on The Startup Story – From an Idea to Our First Customer in 7 Days
it is our concern too, and we are trying to become independent. The costs are quite stable so far, though.
martinadamek··on The Startup Story – From an Idea to Our First Customer in 7 Days
oops, I see, thanks again :)

@vaksel Thank you for the feedback. This is what we need so much! Some of the points (2, 6, 8) we are solving and those should be live this week. #10 there is a counter - '...get an estimate' link (we can do better I am sure). I really appreciate your time spent on this and will try to get better!

@Mc_Big_G for ~100 words it would be ~$2.8 and the 'industry' itself is quite big, but it depends on needs, of course.
martinadamek··on Twitter OAuth on Java AppEngine
Yes, Twitter4J is nice, but I still somehow prefer to handle JSON responses by myself. It gives me greater control and flexibility to API changes.
