This issue has already been fixed in our new flagship app LawStack. If you need help, you can reach us at support@lawstack.com and we will be happy to help you. ### 1/5 — App needs work *2015-10-09* Currently in tax school. The idea of the app is great. Having the regs and tax code at your finger tips. But the highlighting feature is so awful. Every time I attempt to highlight a portion of the code, it's a hit or miss and either it will allow me to highlight or it won't. The app needs to fix this feature **Developer response:** Im so sorry for the inconvenience. This issue has already been fixed in our new flagship app LawStack. If you still have some troubles you can write me at support@lawstack.com and I will be happy to help you. ### 5/5 — Great app *2015-01-22* I'm a tax attorney and need to refer to the Code and regs constantly. This, and the companion Code app, allow me to access the Code and regs simply and easily. The apps are a bit pricey but you get what you pay for--a logical,user friendly, interface and portability of what otherwise would be eight clumsy volumes that would have to carried around. I find this app critical to my work and a major convenience. I don't know what I would do without it. **Developer response:** Hello Jeff, thanks for your support! We are very happy to hear your feedback. You might be also interested in our flagship app LawStack where you can find similar contents and many other apps :) ### 5/5 — Super convenient *2014-02-16* I use this app much more than the print volumes, which are cumbersome and get dusty. I have dual monitors at my computer, so this app is like a third monitor on my iPad. The print is easier to read in the app than on the thin pages. **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 5/5 — Navigation *2013-08-30* Once you learn how to navigate, the app is good. It needs a simpler way to get from place to place. Awfully handy to have on the iPad, though. Definitely worth the money. **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 5/5 — Great improvements over the years *2013-08-22* Easier to go directly to a particular section. Would like to see better navigation to subsections. **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 5/5 — Excellent Resource *2013-03-28* Bookmarks make this a time saving reference for Income tax regulations. Highlight feature is great also. E-mailing a section helps communicate regs. All in my iPad! **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 4/5 — Great tax resource on the go! *2013-02-05* Good mobile resource that is easy to use and allows bookmarks. The fifth star is absent for the vendor to make frequent updates to regs! **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 5/5 — Great app! *2012-12-20* Everything you need for searching the Regs. **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ### 4/5 — Beats the heck out of carrying around 6 books of regs *2012-09-25* As a tax professional, there is no greater burden than the 25 pounds of paper textbooks that constitute the IRS Regulations. This app saves a ton of space, effort, and years of wear and tear on your back! Only negative, that I can see, is that they do not contain the proposed regulations or the preambles thereto (hence only 4 stars). These would be greatly appreciated in future versions. **Developer response:** Thanks for your support! We are very happy to hear your feedback :) ## Frequently asked questions about 26 CFR by LawStack ### Does 26 CFR by LawStack have ads? No, 26 CFR by LawStack does not contain advertisements.
