Cumbersome, Doesn't Work Offline. Needs Polish. This app provides a good range of different fractal types. It explains things well for iterated shape replacement like Koch curve. As for zooming in on details, as claimed in the subtitle, most fractal types can't zoom. I only spotted zoom/pan buttons on the Mandelbrot set. Very cumbersome. See Mandelbrot Maps app for something much more interactive. Also, this app draws tick marks on the axes with crazy spacing like 0.48? I thought Wolfram of all companies knew how to choose good tick spacing like 0.5!

Tony Di Iuorio

Alpha-Powered for same price I can already do 80% of this in WolframAlpha. Why are the input iterations locked? I bought expecting to create cool imgs. Letdown.

## Star Walk - Astronomy Guide

Star Walk is the most beautiful stargazing app you’ve ever seen on a mobile device. It will become your go-to interactive star chart of the night sky, following your every movement in real time and allowing you to explore over 200, 000 celestial bodies with extensive information about stars, planets, satellites, and constellations that you find. Even if you’ve never been that into astronomy, Star Walk will surprise you.

Links:

http://vitotechnology.com/star-walk.html

http://www.facebook.com/StarWalkApp

http://twitter.com/starwalk

Get started quickly

• Launch the app and point your device at the night sky, you'll see the stars, planets, satellites, and constellations in their proper place for your location. As you move your device, the star map updates in real time. The Moon is the easiest first target.

• Tap Augmented Reality icon in the upper right corner to add the image from your camera to your sky view.

• Use Night Mode to go easy on your eyes and preserve night vision when exploring the Universe.

Go deeper and beyond

• Every star, planet, constellation, or deep space object, such as nebulae and galaxies, has an (i) next to its name. Tap it to access information.

• A scale on right is the Time Machine, slide it to explore the map of the night sky of tomorrow or years ago.

• StarWalk has data on over 9000 man-made satellites. Track their flight across the sky, be it day or night, catch iridium flares.

• Meteor showers are spectacular yearly events. Star Walk can help you plan ahead and locate the meteor shower on the night sky.

Share your experience

• Post pictures from your virtual planetarium and let your friends learn about the night sky. Astronomy has never been so engaging!

Duran Duran's keyboard Nick Rhodes mentions Star Walk as his favorite app:

"With the Star Walk app, if you hold your device up towards the sky, you can see all the stars and constellations. It even tells you the names of all the planets. Then, if you point it towards the ground, it shows you what all the stars are in the other hemisphere. It’s brilliant, and if you’re ever somewhere with a clear sky and no light pollution, it’s a revelation. It’s beautifully designed and makes clever use of the available technology. I’m fascinated by astronomy, but even if you’re not, give this a go."

***Note***

- The Star Spotter feature won't work for the devices that are not equipped with the gyroscope and compass.

- For Android 4.4 KitKat users: the application doesn't support ART, please switch to Dalvik.

## Discover Astronomy

Welcome to the world of astronomy: planets, double stars, galaxies, nebulae. These are just some of the amazing wonders that await you when you explore the night sky. But a dark sky with seemingly countless stars can appear overwhelming. Where do you begin?

Start with Discover Astronomy. For decades, the insightful editors of Astronomy magazine have been guiding observers, across the constellations, through the solar system, and into the deep sky so they can get the most from our time under the stars. And now, with this app, Northern Hemisphere observers can take expert guidance with them wherever they go.

Discover Astronomy eases you into stargazing by having you get to know the night sky with just your unaided eyes and binoculars through interactive articles, videos, galleries, and star charts. What are the signpost stars and star patterns of each season? What should you observe first? How can you understand where to look when you hear about a sky event in the news? The answers are all here.

After you feel comfortable with the major constellation guideposts of each season, grab your binoculars and Discover Astronomy to explore the Moon and the brightest star clusters, nebulae, and galaxies. You’ll be amazed by what simple optics can reveal. Soon you’ll be craving the views only a telescope can provide, which this app helps you with as well. Let Astronomy’s editors guide you through the buying process and get you started observing the planets, the Sun, and hundreds of stunning deep-sky objects. In no time, you’ll be exploring the sky like a pro and sharing your knowledge with others.

To load a file:

1 - the first time, do "menu", "tool", "load on stack", and abort, this will create the right directories

2 - then download (from http://www.hpcalc.org/ for example) the raw file you want to load and put it in 'sdcard/go49g/files' with a file manager (i.e. Linda manager or Ghost commander)

3 - on kitkat device import/export is now at /Android/data/o2s.emul.hp49g/files instead of /go49g

4 - next do "menu", "tool", "load on stack" your file should appear, choose it

5 - as told by the pop up, now press 'ON' key to refresh stack display

6 - et voilà, your file is loaded on the stack, now do what you want with it

7 - if you don't know what to do with it, get and read an HP49 manual !

Actually:

- no grayscale support.

- serial only as printer.

Avoid checking 'force gpu rendering' in developer option in android 4.x prefs, this leads to graphic problems.

On S5 devices, long press the right hardware button to get the menu.
