With a spreadsheet, you spend too much time filling in fields with data and formulas. If you have actually ever plotted out a number of calculations on the back of an envelope (this is why Val-Pak coupon mailers are TRUE junk mail - they don't leave any space to legibly write anything on the envelope), you know how you go back and forth between pencil/paper and calculator screen. Soulver is great as a "plain language" calculator. An "easy percent" function is also included allowing you to designate the percent sign to be "% off," "% on," or "as % of." This works great for keeping simple tabs for invoices, recording expenses for a trip, splitting up multiple bills over multiples transactions, etc.Īll the basic functions you need to perform trigonometry are included. Soulver saves work that you have done in individual files - up to 20 if you change the default settings - so you can pull up old calculations and reference them. Like a spreadsheet, soulver lets you reference individual lines to create new formulas. Like an adding machine, Soulver shows all transactions that you have performed so far in a column with totals. Instead of simply showing a running total, the way a standard calculator does, Soulver lists all your calculations that got you to your current figure. And if the envelope reference feels at all like home to you, you'll understand how Soulver sits halfway between a plain calculator and a full-blown spreadsheet app. What makes Soulver special in the calculator field? Acqualia touts it as "an everyday calculator" or your "back on an envelope" numbers app. For the truly hardcore, there are even at least three apps that turn your iPhone into a classic slide ruler. The answer is: "Of course you do." RPN calculators, construction/carpentry calculators, mortgage/annuity calculators - even the ubiquitous tip calculators - all have their uses and - ahem! - functions. Flashlights, mirrors, dice rollers - do we really need any more of these? Or are they simply what every developer first learns in their "Intro to iPhone Programming" book/class and so they go ahead and publish them in hopes of making back some money on their educational investment? Does anyone really need anything more than a basic calculator? Rubik's Cubes of 2, 3, 4 and 5- order included.Calculator apps are one of those categories in the App Store that just seems to be flooded. Tilt the phone horizontally or vertically to change the viewing angle of the Rubik's Cube. After the face marked, subsequent rotations will generate guide lines to show the rotation action. Double-tap on the face of the cube to mark the face double-tap again to remove it. You can also tap the Undo button to undo the last action. Swipe through the blank area to rotate the cube. Swipe the cube with your finger to rotate the layer of cube. Realistic 3D graphics makes you feel playing with real Rubik's Cube. Playing Rubik's Cube on iPhone feels playing a real one! Tips: If the cube is not recognized when you scan it, you can rotate a random face of the cube and try scanning again. Note: Automatic recognition of the Rubik's Cube needs to be done in a well-lit place, dim lighting environment will lead to recognition failure. Place the Rubik's Cube in front of the camera, follow the prompts to scan the 6 Rubik's facets in turn, and then this app will show you the steps to solve the Rubik's Cube in 3D step by step! Spent hours solving the Rubik's Cube, but still can't solve it? Try this app! Solve 3x3, 2x2 and 4x4 Rubik's Cube with your iPhone's camera.
