Too green ? Too simple ?

Idea is pretty good actually.
Hero text is clear, I know what your page offers: convert audio to text from whatsapp.
Green background is also fine.

You need to improve the feature section's layout a bit, it feels off. The spacing between the elements should be revised.
"No more audios" sounds a bit weird for me. Something like "write messages with your voice" would be better.

Good luck with your app.

@lnalex - I think this is the best idea I've seen on IH this week. Nice work!

I like:

• A very clear, simple and high potential idea
• Great UI and branding, good enough for the idea stage
• Easy to read landing page, not many buzzwords, and jargons
• Huge market size, basically every Whatsapp user who would do voice message

Can do better:

• Include a real demo, maybe a short video or GIF?
• Nice you've mentioned privacy, it would be nicer if you can mention more
• Milestone? You can also include your future expansion plan (if you've) to other messaging apps

I really love the LISTEN TO READ YOUR VOICE MESSAGES bit. That really made it clear what the app does for me.

And it gives me an excuse to use Markdown syntax I've never used before :)

Some grammar issues:

"don't have headphone" should be "don't have headphones"

"Check these Textible.app amazing features" should be something like "Check out Textible's useful features" (the word 'amazing' is a bit hyperbolic)

"Because not everybody use WhatsApp and we value our user feedback, we try to get most of our feature. So, stay tuned to get noticed when it will be available for other apps." Is difficult to understand. Should be something like "If you're not on WhatsApp, stay tuned for when Textible will be available for your messaging app of choice."

"Get noticed" should be "Get updates" or "Stay in the loop"

"Keep in touch of the Textible.app release. Straight in your mailbox !" should be "Get updates on new releases straight to your mailbox"

The lorem ipsum text on the images really stands out to me. I would consider changing this to something else that is more suited to a WhatsApp audio message.

My first impression is that there is no clear focus. Everything is big and screaming for attention.

• I would make "TEXTIBLE.APP" a lot smaller, it's just the name/logo of your product, doesn't offer any useful information.
• This should be the biggest text on the page, as it explaines what your app does: "Transform your Whatsapp audio message to text." -
• THERE IS TOO MUCH CAPITALIZED TEXT. No reason to shout at the customer.
• Also, there are at least 6 different font sizes above the fold.
