Ink, BrainFit, Wallaroo, and other apps to check out this weekend

Congratulations on making it to the weekend again! This means it’s time for another Apps of the Week roundup, and oh boy do we have some great picks for you. There’s an AI writing app, an app for making your brain healthier, and a fun wallpaper app. And as always, we’ve selected a great new game for you to check out.

Ink – AI Writing App With Chat

Yes, I fell for another AI app. This one is called Ink, and it looks more polished and useful than a lot of the others we’ve covered. It’s pitched as the ultimate writing assistant for anyone looking to create high-quality content quickly and easily. You can generate texts on different topics and categories with the help of AI, or you can talk to it directly via the built-in chat.

BrainFit – Habit Tracker

Here’s an app to help you protect your brain. Optimize your brain health with BrainFit, a habit tracker to help guard against dementia by building habits in the Six Pillars of Brain Health. Essentially, it focuses on exercise, nutrition, stress management, social activity, mental stimulation, and sleep. It’s private and confidential, and is continually updated with the latest research.

If you’re looking for a way to get your wallpaper fix in between our weekly wallpaper roundups, this app might help. It’s called Wallaroo, and it’s made by Iconfactory—the same folks behind Twitterrific. The app features tons of wallpapers, organized into categories like abstract, nature, anime, etc., and new, topical content is added weekly. Note that some of the content is hidden behind a paywall, but if you’re familiar with this team’s work, you know it’s probably worth it.

Color Sign

Color Sign challenges your mind and tests your reflexes. It’s a super simple game — there’s no loading, sign in or tutorial — just tap on the screen to stop the arrow where the colors match. The faster you match, the higher your score, and the higher you’ll rank on the global leaderboard. The game helps sharpen focus and concentration, and improve your hand-eye coordination and reaction time. Hey this kind of goes back to that brain health thing.
