Updated for iOS8!

The A.P.S. Tuning Trainer is unique app. that approaches ear-training from a completely neglected angle -properly tuning an instrument or note... and it DELIVERS almost IMMEDIATE results!

What if you could have the confidence to tune your notes, instruments, and ensembles (voice or instrumental) and be accurate to within a 16th of a semi-tone with complete confidence? The answer is... everything you are doing musically would improve -including the confidence level of your own tuning abilities.

A.P.S. Tuning Trainer was developed from the "ground up" by veteran ensemble directors experienced in ensemble and individual tuning methods. This app features an incredible amount of options all designed to do one thing: make you unbelievably precise with regard to accurately comparing two different sounds or notes.

The objetive of this app is to make you as proficient as possible and hopefully, to become accurate to within 12 Cents ( a measurement of pitch space) of a note. 12 Cents is less than 1/8 of a semi-tone apart! A.P.S. Tuning Trainer accomplishes this goal by presenting a myriad of pitch examples and includes the ability to review them after the correct answer is known. It also presents the user with an unprecedented amount of "real-world" options that typically will cause confusion (undermine) with regard to a user being able to determine whether or not a pitch is "In Tune":

1. Three complete octave range choices (and the ability to combine them)
2. The ability to make detection "harder" or "easier" by changing the pitch variance (1 to 50 Cents and pitch variance ranges!)
3. The ability to change the Timbre of the Reference Pitch
4. The ability to change the Timbre of the Determinant Pitch
5. The ability to control how long a pitch is presented
6. The ability to change the time (in seconds) between the two comparison pitches

A.P.S. Tuning Trainer also keeps a score of your success and shows the current pitch variance settings (useful screenshot proof!).

INCLUDED in the manual (and on our website) is a FREE, 4 week (20 day) curriculum that all but guarantees mastery of precise pitch discrimination. It does this while only requiring 20 minutes, per day, of practice!

There isn't a musician out there that WILL NOT benefit from the ability to more accurately tune themselves and others AND the A.P.S. Tuning Trainer is now here to make sure that benefit happens as quick as possible!

Customer Reviews

what everyone needs


As a high school music teacher I'm really happy I found this app. I'm playing with it over the holiday break and plan on using it in my classes when I get back. Just got an Apple TV for the classroom so I can walk around the class with my Ipad while we work on this. I agree with another reviewer that being able to hear both tones at the same time would be an important step forward. I'd like to be able to save my sessions somewhere in the program too, rather than having to do it in another program. Also, maybe a built in timer would be a plus. Thanks for a great program!


Great App - Extremely Effective!


This app is an extremely effective tool for all musicians. I used it with my daughter, a freshman college music major, and her sense of pitch improved dramatically in the first 30 minutes. She also enjoyed the process and musical challenge as she moved through the Easy, Moderate and Difficult levels. The random timbres are very effective! I highly recommend this app to any musician as they train their ear to hear minute discrepancies in pitch. Music teachers will find this an invaluable tool for implementation in any classroom.

I have been looking for this for a long time. I actually wrote a program like this many years ago for the Atari 400. I would suggest an option of how many questions would you like. Also a guide as to what is considered mastery would be helpful on the curriculum. I have been teaching a long time and intonation is one of the hardest things to teach. This app should really help. Especially since we are requiring all of our students to have iPads.
