iOS developers being threatened with patent infringement over in-app purchase system [Updated]

By Rene Ritchie, Friday, May 13, 2011 a 9:39 am

Developer James Thomson reported on Twitter this morning that he's been threatened with patent infringement for his use of in-app purchases in PCalc Lite.

Just got hit by very worrying threat of patent infringement lawsuit for using in-app purchase in PCalc Lite. Legal docs arrived via fedex.

No idea what to do... They seem to be effectively claiming the rights to in-app purchase, but going after me, not Apple.

Developer Spotlight: James Thomson of TLA Systems

By Rene Ritchie, Monday, Apr 25, 2011 a 2:34 pm

TiPb's developer spotlights are like DVD/iTunes Extras for the App Store -- a weekly look behind the scenes at the programers and designers that bring you the iPhone, iPod touch, and iPad apps and games you love. This week Rene talks with James Thomson of TLA Systems, and PCalc fame.

What's your name? James Thomson

What's your company called? TLA Systems - and yes, that does stand for "Three Letter Acronym". It was originally a fake company name I made up with friends to get us into trade shows while we were still students. I kept using it, and now it's a real company employing myself and my wife.

Where are you located? We're based in my native Glasgow, on the west coast of Scotland. It can be a bit dark, cold, and wet, but I wouldn't want to live anywhere else - you need the dark to appreciate the light.

What's your website address? http://www.tla-systems.co.uk/ and http://www.pcalc.com/

What's your Twitter handle? I'm @jamesthomson - that's my personal account, but I tend to use it for work too.

What are some of your apps? Our main app on iOS is the scientific calculator PCalc, which is in turn based on PCalc for Mac OS X. We're also known for DragThing, the dock app that pre-dates Mac OS X.

What other apps do you currently like? NanoStudio is great for writing music on the move - it's more powerful than GarageBand in many ways, and runs on my phone. I'm not really a musician, but I do enjoy tinkering. Shazam still seems like magic to me - it's invaluable for identifying background music on TV and in shops. RedLaser is the best app I've come across for barcode and QR code scanning. The Chambers Dictionary and The Chambers Thesaurus apps are also both very good. I'm also still playing Game Dev Story - it's a game all developers and journalists should play!

PCalc 2.3 now available for iPhone, iPad [Give away]

By Georgia, Friday, Oct 15, 2010 a 5:05 pm

PCalc, one of our favorite iPhone and iPad calculator apps (see Leanna's PCalc review), has just hit version 2.3, and in celebration the developer has very kindly offered us a bunch of promo codes to give away. To you. But first things first:

This free update has many improvements, but the key one is taking advantage of the additional screen space on the iPad. You can now permanently show the paper tape, RPN stack, and memories onscreen in a new sidebar area. This was the number one requested feature from iPad users, and we're happy to be able to add it now.

The tape, stack, and memories have had a complete overhaul for the iPhone and iPod touch too, and are now easier to read across all devices, appropriately themed, and with enhanced email support.

PCalc is distributed as a universal app - one purchase will work on iPad, iPhone, and iPod touch. No need to buy a separate "HD" version. It requires an iPhone or an iPod touch running OS 3.0 or later, or an iPad running OS 3.2 or later.

Give away after the break!

Quick Review: PCalc for iPad

By Leanna Lofte, Friday, Apr 16, 2010 a 1:24 pm

PCalc [$9.99 - iTunes link] is one of the leading calculators for iPhone and now its computing power has been updated (as in universal binary) to include support for iPad.

PCalc is an (optional) RPN calculator that is great for scientists, engineers, programmers, and students. It includes a list of common constants, an ample amount of conversions, a paper tape that can be shared via email, and support for binary, hexadecimal, and octal calculations. You can also customize the look of PCalc with different themes and digit fonts.

The interface on iPad is rather beautiful in both landscape and portrait. The buttons are nice and big and everything is easy to read. Navigation between the menus is a much more pleasant experience than on the iPhone.

To see PCalc in action, watch the video after the break!
