For those iPhone users out there who are interested in RTTA (Real Time Tuning Analyis), I have written an app called RTTATuner that is now available on the app store. Sorry, unfortunately there is no Android version - anyone out there who wants to take a crack at it? As I put a lot of work into this app, I am charging US$4 for it.
By the way, I’ll give a present in the form of an iTunes voucher to the first person to tell me the significance of the app icon 
Just pm me if you think you know the answer…
I hope you enjoy using it.
Note to moderators: I think I’m abiding by the forum guidelines in making this announcement - I have certainly tried to…
Cheers, Dan
I just bought this to run on my iPad. It is excellent! It is so easy to use, and so informative. I already burned an hour playing various antique and modern flutes in front of it, and I can tell I’m going to be spending a lot more time with it! Thank you for making this available to us!
Many thanks for the kind words Paddler. I’m glad you liked it.
A hint about the app icon - it has something to do with a historical document, a composer, and temperaments.
Cheers, Dan
The winners of the contest for the significance of the app icon are Philippe Alain-Dupré and Godfried Croenen. As they pointed out, it is a close up of one of the ornamental flourishes on the title page of Bach’s Well Tempered Clavier. Other flourishes on the page have been interpreted as giving a cryptic clue to the temperament used by Bach. I used it for its connection to temperaments and tuning, because it looks somewhat like a crazy treble clef with warped staves (perhaps indicating mistunings or flexibility of tuning) and because I play baroque flute and appreciate that music.
Thanks to those who guessed!
Cheers, Dan
Hi Dan,
great app! Could you include a way to turn off the auto-off-feature from within the app?
Best, Moritz
Just bought it… Great app! Much more convenient than dragging out the laptop to run the application. Seems to be pretty accurate, too. A nice addition would be the ability to export a PDF of the results. Are you planning an iPad version?
Pat
Hi Moritz and Pat,
Both are excellent points.
A few people have asked about an export function, which in hindsight I should have put in from the start. Is having a PDF important to you, Pat, or is export to text via email also a good way to go?
Moritz, I believe the answer is: yes. It seems obvious in hindsight!
Both improvements, along with one or two extra temperaments, will be included in the first update that I’ll put together in two or three weeks.
If anyone else has anything for the wish list, please pipe up!
Also, don’t be shy about posting a rating or review to the app store - this helps me out…
Cheers, Dan
If it exports a PDF, you can “open in” another app, such as iBooks or ForScore, etc. It’s not that important, but it would be nice… Also, I edited to ask if you are planning an iPad version.
Pat
Mentions on the description page (linked above) that it’s compatible with an “iPhone, iPad, and iPod Touch”. Am I misinterpreting?
Best wishes.
Steve
It doesn’t come up in a search with my iPad…
Pat
And on the RTTASupport site it only mentions iPhones. Have to wait for the OP to check back in and clarify I guess…
Best wishes.
Steve
I’ve been running it on my iPad.
Jon
@Jon: does it run as an iPhone app or a (full screen) iPad app? I can’t find it doing a search for “RTTATuner” using my iPad…
Pat
There have been questions about the iPad compatibility. It’s partly down to Apple quirkiness.
I didn’t specifically write in iPad compatibility, and specified iPhone when I wrote the app. But it is possible to run in “iPhone” mode on an iPad running iOS 7.0 or later. You will either see a magnified view of the equivalent of an iPhone screen, or a little iPhone screen in the middle of your iPad screen. I have personally only tested it on my iPad mini (it worked well), but others report running it on regular iPads, I believe.
When you’re searching the app store using an iPad, you need to first run the search (e.g. for “RTTATuner”). No results will come up, but in the top bar, near the “Cancel” button, there will be a drop down menu from which you can select “iPhone only”. If you do so, the listing for the app will come up and can be purchased.
Hope this helps,
Dan
PS somewhere down the track I’ll write an iPad specific UI - maybe on the second update.
The app is running in full screen mode on my iPad. It is not at all obvious that this is an iPhone only app. It seems to run flawlessly, in full screen mode on my iPad Air. To get it I simply followed the link posted here, downloaded it and ran it. [Edit: I’m running iOS version 7.0.6].
Mine runs full screen on the iPad, too… Seems like you don’t really need to release an iPad version after all - just make sure that iPad users know how to retrieve it.
On another “note”… I have noticed that the app seems to pick up notes that I haven’t played, like B-flat on my D flute. It it, perhaps, catching the transitions during rolls, etc, and thinking they’re regular notes? Not a big deal, but it kinda messes up the “picture”.
Pat
Hi Pat,
You’re probably right, it’s most likely catching stuff between and at the edges of notes, especially if you’re playing a lot of ornamentation and quick notes. It should help to increase the “min readings” setting. This will suppress the display of any notes that haven’t registered more than a minimum number of ‘readings’.
It occurs that I should also have a “min % of readings”. I recall that Scott had this in Flutini and Graeme in Polygraph. Another minor change for the next release…
Thanks everyone for the feedback - it’s really helpful.
Cheers, Dan
Speaking as a maker, this thing is an awesome tool at ten times the price. Just started messing with it and I can already see that I’m going to be using this a lot.
Oh, jeez. Don’t tell him that until we’ve all bought one… 
Best wishes.
Steve
