"I love it !!!! This is the best app ever !!! - I would thoroughly recommend it - and it has been very helpful"

"Creates an amazing feeling that anything is achievable with the right guide and support. Thank you so much for making this App available for everyone"

"If you can’t / dont want to access voice therapy face to face for whatever reason, or you’re looking to supplement your face to face therapy – I’d definitely recommend it!"

"Not cheap but worth it as really good and really is life changing when what comes out your mouth match your mind and body"

### 2/5 — Too much repetition, not enough instruction

*2024-05-22*

I grant I’m likely a difficult student, having tried about half a dozen online and in person voice therapists with absolutely no progress, but this was another strikeout.  For, say, intonation or vowel lengthening, even in the first lesson, the instructor just has you repeat what she’s saying with no real guidance as to how one varies intonation or lengthens vowels.  Pitch and resonance had slightly more instruction, but not nearly enough.

**Developer response:** Please get in touch at support@speechtools.co and we'll be happy to help

### 4/5 — Christella VoiceUp Review

*2023-05-16, version 4.3.2*

I would have liked a booklet/book explaining much more about each of three parts, especially for the price. I can’t remember if any transcripts are available for each part. The teaching takes a gradual progression to improve voice change. Practice is essential. Thank you Christella.
I have received an update which says they will see if this could be done in the next update. I hope this is possible, as I will be grateful.

### 1/5 — Nothing but a recording app

*2023-02-27*

Complete waste of time and money. There is NO instructions on how to modify your voice. The app has you read sentences and tells you what percentage male va female your voice is. It does NOT instruct you in any way on HOW to change your voice. There is no demo to see what it offers. You pay $19.99 and get absolutely nothing.

**Developer response:** Hi, sorry to hear you think that but the app does deliver Christella's proven therapy and guidance on how to feminise your voice. It also allows you to record, analyse and monitor your voice journey - provided for free. Each of the 3 stages has a free sample to show you what is contained.

### 5/5 — Wonderful App!

*2022-09-05*

I’ve found this app extremely helpful compared to other resources I’ve used. Having gone to speech therapy as a child, this is much more like the type of practice that has helped me before. 

I still supplement this with other trustworthy resources I’ve found elsewhere, but this is the best, most affordable, most helpful, and most available option for getting a speech therapy experience short of actually seeing a therapist for appointments. 

I also like how it gives you a place to store your progress recordings. I had previously just emailed myself clips and stored them in email, but this allows me to scroll through and see/hear my different outcomes and progress over time which is super helpful!

Thank you so much for making it! I hope it helps others like it’s helped me!

**Developer response:** Hi, thanks for the feedback and really happy to hear it's helping!

### 4/5 — saving system is a bit odd

*2022-05-25*

currently doing the course, and this app is really good, but for some reason when i clicked save on the voice thing it replaced it with a completely different audio clip that i didnt even save

**Developer response:** Thanks for the feedback, we've got that fixed now!

### 3/5 — Hmmm

*2021-02-13*

I love the idea of this and would love to make use of it, but £60 fir the whole course is far too high!
Sorry maybe if you make the price a lot more reasonable. 😢

**Developer response:** Hi, we hear you so we've reduced all content by 50% in support of International Pride Month June

### 1/5 — It sucks

*2020-11-20, version 3.3*

Barely anything in the app and it’s horribly organized , I even tried with a male voice and it said 100% feminine really bad app either fix it or scrap it 🤦‍♀️

### 5/5 — MtF Voice Gamechanger

*2020-07-29*

I saw Christella in person about four years ago and she contributed a lot to my voice changes. From time to time I return to previous patterns and I’m really thankful she created this app to revisit the exercises I already practiced during my visits, it’s like taking her coaching with me everywhere I go!

**Developer response:** Thanks for the feedback and we're really glad to hear it's helping!

### 1/5 — Not worth it

*2020-07-28*

I bought the first lesson and literally it’s was the worse twenty dollar the I have spend in my life

### 5/5 — Fantastic value ! Simple and informative

*2020-07-20*

This is a fabulous app, a great deal of thought has gone into the 3 courses.  Very easy to use, the practises are done in a way to develop your voice at your convenience.

There a sub sections to practise with, common and useful life situations in speech has been helpful to me. Social life, work and office, telephone, appointments. 

It’s done wonders for me, though I have been dedicated to it using it religiously everyday and has provided me with an increased level of confidence with my voice. 

I had a one to one session with christella via Zoom, she was so great with that also. 

I truly believe this app is the go to for developing a female voice. 

Thank you Christella 
Bridget.

**Developer response:** So glad to hear we've been able to help
