## What is SolarWriter?

Turn your Kindle or e-reader into a sunlight-readable, distraction-free typewriter!

Traditional screens are fantastic everywhere but outside, especially on a sunny day. E-ink screens work well, but e-readers like the Kindle are difficult to type on and don't support external keyboards.

SolarWriter gives you the best of both worlds.

SolarWriter runs on your iOS device and acts as a hub between your keyboard and your e-reader. You type on the keyboard, and the text appears on both the iOS device and the e-reader's screen (via its web browser).

Take advantage of your Kindle's (or other e-reader's) e-ink screen to put your thoughts on the page even outside, with no need to transcribe later.

Write at parks, on beaches, in backyards... anywhere you wanted to, but couldn't.

Save files on your device, or share through email, SMS, and more.

Detailed instructions for setup are included inside the app.

### 2/5 — Irgendwie sinnlos

*2025-11-30*

Es ist eine nette Idee, einen Kindle mit einer externen Tastatur zu benutzen. Leider muß das iPhone oder iPad, auf dem die App läuft, die ganze Zeit den Bildschirm eingeschaltet haben, damit es funktioniert. Dann kann man doch gleich darauf schreiben und muß nicht über den Kindle gehen. Irgendwie sinnlos, diese App.

### 4/5 — Makes Kindle a modern typewriter

*2024-10-08*

Great app, love this! One thing i urgently need: allow more fonts in the settings tab. Serif and sans-serif are not enough; in particular, I would love to see some monospaced typefaces, such as Consolas.

### 4/5 — Very neat, kinda kludgy.

*2024-09-05*

I mean that affectionately. This app represents a clever way of getting around limitations. There are some convenience factors that I wish were possible, but it’s not the app’s fault that they are not present. Like turning off my phone screen, or syncing documents to cloud storage. I wish the app made it clearer as to where exactly your documents are stored. You can email them to yourself, which is a pretty good way to save your docs elsewhere and continue your work later.

I have had a little trouble getting it to work on some networks; I get ERR_ADDRESS_UNREACHABLE on some networks. Might be WiFi security settings.

### 1/5 — DELETED MY WORK TWICE

*2024-07-23*

I had about 500 words in a document and suddenly it deleted all of it. Then it did it again, after I decided to give it another shot. I checked all the files, tried to do cmd + z to undo it. It’s just gone. Suddenly the page will just go blank, and all that work is gone. This is obviously incredibly frustrating to lose work, and now I’m afraid to use it in case it does this again. I thought SolarWriter was better than this.

**Developer response:** I'm really sorry to hear that. SolarWriter saves your work every few seconds, but perhaps all text got selected on your mobile device (as with a triple-tap) and then was typed over. I'll see if I can find a way to prevent this from losing work in the future.

### 4/5 — It works! 🤩

*2024-07-18*

Works surprisingly well for a basic typing/journalling. I can now use my 13 year old e-reader as an e-ink monitor for my writing. I can send the notes to myself via email to organize for later. As long as your e-reader has a basic web browser, you’re good to go. Wish the pro version was a little more affordable.

### 4/5 — Brilliant if it worked

*2024-04-21*

It would be brilliant if it worked but it isn’t working. I have a kindle voyage, which it explicitly says works…

**Developer response:** I'm sorry it didn't work for you! I test it on a Kindle Voyage, but certain mobile network carriers and home networks seem to cause a problem for some folks.

### 1/5 — Can’t Get it To Work

*2024-03-12*

I’ve got everything set up as described in the help doc, but my kindle can’t load the webpage at the provided IP Address. It gives me an error about the browser “being designed to render simple webpages.” And the big “Upgrade to Pro” takes up so much space. Really in your face, made it hard to give it a real try. 

If it worked, I’d probably buy it. This solution is really clever and so much cheaper than buying a proper e-ink typing device.

**Developer response:** I'm sorry it didn't work for you! I think that message is from Amazon testing some new Kindle features, if you can move past the message you may be able to try again.

### 5/5 — An inspiring piece of software!

*2023-11-24*

I don’t often leave reviews for software, because much of the mobile software I’ve used in the last 10 years is either overpriced, bloated or short of my expectations. 

SolarWriter is an awesome piece of software, and I appreciate what it has done for my writing workflow.

### 3/5 — Functional but limited

*2023-10-06*

I typed part of this review on my iPhone 13 Pro, and the rest on my apple silicon MacBook Pro, using my Kindle Paperwhite as a secondary display. 

It works, and allows you to send the finished document to email, text, etc., but there are shortcomings:

Unfortunately it's very laggy, at least on my 11th gen Paperwhite. It is easy on the eyes, though!

Another issue is that I can’t use the Kindle screen as a touch interface to replace having a mouse. So in IOS, I have to use the on-screen or Bluetooth keyboard to move the cursor, edit text, save the finished file, etc. On the Mac, I was able to use the mouse and keyboard.

Highlighting, cut and paste, etc., are not an option either. 

Emailing anything I create is easy using SolarWriter on the iPhone or Mac, but I don't see a way to do that on the Kindle.
