What's New in Strobe

Markdown. Import Markdown files, including notes from Obsidian and other notes apps. Headings become chapters, and formatting, links, and code stay out of the words. Pauses between paragraphs. Headings, list items, and paragraphs that don’t end in a period now get a pause, just like the end of a sentence. This works in books, Markdown, and pasted text. Smoother voice. Read Aloud says “the” and “a” naturally, based on the next word, and pauses between paragraphs.

Four suggestions

Clean, simple, and does what it needs to with zero problems.

Suggestions:

1. Using two fingers triggers the text to continue flashing on its own, hands free. If this is a bug, do NOT fix it; it’s pretty useful. If it isn’t a bug, there should be some type of pointer or indicator to highlight and demonstrate the feature. I had only stumbled on it by accident, and I don’t remember there being any indicator for it.

2. Add an option to change the color of the highlighted letter.

3. The estimated remaining reading time is based on the base wpm, cool. But it doesn’t include any of the timing settings variables that can slow it down, so it doesn’t (100%) accurately show the real reading time.

4. Add an option to change the opacity and size of the floating quotation mark.

Response from developer

Thank you so much for your review! Ha, your first suggestion is indeed a bug. I will look into turning it into a proper feature. The rest of your suggestions sound great. I will look into adding them in the next update. Happy reading!

We love OPEN SOURCE!

Huge thanks for making this app! for 5 stars we need a few things: on ipad, ability to move between chapters that isn’t a slide bar as it can’t be specific enough to the right page/chapter 2) a way to read without having to hold the screen - I have trouble holding my arm out for that long while reading. Thank you!
