The idea is pretty simple:

Audio books and E Books are sold separately. I want them to be merged into one format so I built an E-reading app that uses ai voices to turn all ebooks into audio books seamlessly.

You can instantly go from reading, to listening or even do both at the same time (which improves memory and comprehension).

Im really proud of how this has come out. I Genuinely don't think any reading app on the app store is close to as good (I'm obviously biased). I used to read on my kindle mostly but now I exclusively use my own app, read faster and remember more.

Ive made it free to use with 30 minutes of listening a day (you can read as much as you want). Then for unlimited listening its $8 a month of $50 a year.

Would love to hear anyones and everyones feedback on it. Im making it my mission to build the worlds greatest reading experience.

Its called Morph Books: https://apps.apple.com/us/app/morph-books/id6760332618

The product

Morph is an iOS reading app. Import any EPUB, pdf or web article, and you can read it, listen to it, or do both simultaneously with word-by-word highlighting synced to the audio.

The TTS runs fully on-device — no internet, no cloud processing, no usage caps. I rearchitected the Kokoro TTS model to run at 20x realtime on iPhone CPU without overheating the phone. The only other app with a local tts that sounds this good is Speechify and they cost 2x as much. The app also has an AI assistant that can answer questions about the book you're reading, in context.

Use case: anyone who reads ebooks and wants to listen too without buying a separate audiobook. People with ADHD/dyslexia who retain more with dual-channel input. Anyone who wants to "read" while commuting, cooking, working out.

The market

Audiobook market is ~$7B and growing 25% yearly. EPUB/ebook readers are a commodity. The gap is the middle, apps that do both reading and listening in one place.

The long term thesis is that people will no longer need to think or remember anything to live because AI will do it for them. But just as no one needs to go to the gym to survive, people want to. I predict the same will happen with books.

Competition

- Speechify ($139/yr): Like every other tts app, its build for listening, not reading. It turns anything in an audio book rather then enhancing the reading experience.

- Audible ($15/mo): great for audiobooks but forces you to buy the audiobook separately from the ebook. Two purchases for the same words.

- Kindle Immersion Reading: read + listen but requires buying both formats.

- ElevenReader: Cloud-dependent, much more expensive and same issue as speechify, too much focus on listening.

How Morph is different

- On-device TTS — no cloud, no internet required, no word caps

- Word-level highlighting synced to audio, not sentence-level

- One app for reading AND listening — import an EPUB once, do both

- $8/month or $50/year — 64% cheaper than Speechify annually

- No trial traps, no dark patterns

- Designed for reading and listening. Not just listening to books.

Stage

Just went live on the App Store. 2 active trials. No funding, no team, solo dev. I

Customer conversion strategy

Honestly, still figuring this out. Got the 2 trials from an Instagram post. Started posting on technical subreddits (r/TextToSpeech, r/LocalLLaMA) about the on-device TTS work — got attention but hasn't converted to downloads yet. Planning to have automated organic reels.

No ad budget.

Why me

Reading rewired my brain and changed my life for ever. That's why I give a shit about this problem. I think most people in my generation (Gen Z) are literally losing their cognitive function and I believe reading is the antidote.

I also built the everything myself, got Kokoro TTS running at 20x realtime on iPhone CPU when every other iOS implementation maxes out at 3x and overheats your phone. That's not something a competitor can just copy overnight. I have by far the best app for this on the entire app store. Its just about distribution.
