ere is a list of my favorite iphone apps with a short review:
Rock and Gems- This app was just released Jan 19th and I found it the other day so I haven't gone through it fully, but it has quality images of specimen samples. I'll add more info later when I have time to sit and play with it a bit. . Only 99 cents so worth the pictures. Pretty rocks are always nice to look at when bored at the doctors office.
QuakeWatch- gives you the latest news on earthquakes around the world, with links to USGS for detailed information and maps.
Tasa Geology- Kinda neat for the kids to learn about plate tectonics. Hard to believe that in the 1960's this was a huge debate. (Not too long ago when you think about it.) Only drawback is they do not display the movement of the plates as postulated by scientists throughout the time periods. It would have been nice to see that perhaps added in the future update.
Units- gives conversions for an array of things -area, speed, pressure, currency..
Math tasks- coordinate geometry.-Could have used this when digging that trench in Jordan for sure! Not that I can't do geometry by hand, but when it is 120 degree F, your brain just isn't working at full capacity.
ichemistry- has a nice periodic table and balances equations. Also has a mass calculator (reactants/products). This is an okay app, but a bit limited.
ChemiCal- this will calculate stock dilutions and also has a nice periodic table. Also calculates molarity/mass/vol etc. The formula mass calculator section is pretty nice. Another nice aspect of this app is the detailed listing of general information. It offers atomic number, avg. mass, monoisotopic mass, electron config, electrons per shell. Physical properties are also listed : crystal structure, density, melting points. Common isotopes & ionization energies etc. One of the better chemistry apps out there IMO.
The Converter- This is a monster. Does everything from gas consumption/capacity & volume/ mass & weight/currency/clothing (tells you conversion sizes in US, UK, Aus, Eur, Jap, Belgium Spain and France to name a few!)/kitchen (dash, UK teaspoon vs. US -really nice)/angles/ etc etc. This is a great app for those going overseas, or who do any type of conversions.
AppBox Pro- while some of the apps I have are repeated in this handy app of many, this is still a good app to have. Gives batterlife/clinometer/currency/date calc/loan calc/icalendar/sale price/tip calc/units/translator/ruler/price grab/holidays/flashlight/days until/ google books/collapse.. all in ONE app. So for those who like things simple, this is an all in one combo.
MetPetDB- Shows you rock samples of whatever area you may be exploring. This is a new download for me, so haven't used it in the field, but the premise is awesome!
I have a ton more apps, but this will do for now. I'll add to this as I find time. Hope it helps you fellow iphone app lovers out there! ;0)
