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 on the iOS device and on 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 paper 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.
Gua

Gua helps you use your phone on purpose. Most screen-time tools are easy to ignore — one tap and the block is gone. Gua is built on a simple idea: breaking a commitment to yourself should take more than a tap. So you set up "lines of defense," and getting past a block means going through them first. BLOCK WHAT PULLS YOU IN • Schedule blocks for the hours that matter — mornings, work, wind-down. • Set daily time limits on specific apps and websites. • Block by app, by website, or by whole category. PUT REAL FRICTION BETWEEN YOU AND THE SCROLL Choose one or more lines of defense. To take a break from a block, you pass them first: • Accountability buddy — a friend approves your break. • Create something first — write, record, or sketch before you consume. BUILT TO KEEP YOU HONEST • Weakening a block requires passing your defenses — no quiet backsliding. • Take a timed break when you genuinely need one, then it re-blocks automatically. • See your streaks and progress over time. Gua runs on your device using Apple's Screen Time technology. Your block list never leaves your phone in a readable form. Start with one block and one line of defense. Small steps, real change. ``` ### What's New (for v1) > The first version of Gua. Block apps and websites, set limits and schedules, and > put a real line of defense between you and the scroll. We're a tiny team and we > read every piece of feedback — tell us what you think.

Verdict
The clearest difference is in-app purchases: Gua at none against SolarWriter's 1. Gua also leads on update cadence (every 10 days vs every 5 months). SolarWriter's advantage is iOS requirement (15.6 vs 17.0). On price, ads and device support there is nothing between them.
