Comments on CAPTCHA for Sleep as Android for Android

★★★★★ ek.c_bear · Sep 5, 2024

Great for tracking/learning about sleep habits & excellent alarm features for people who are difficult to wake.

★★★★☆ Normal · Oct 5, 2025

This is a great add-on with a wide variety of excellent captcha options, but I did have difficulty figuring out how to use multiple captchas. I googled it and found a forum where it was explained, but it still took me a while and a good deal of back and forth to figure it out. If the multi-captcha option was easier to figure out, this would be an easy 5-stars. Even so, definitely worth it!

★★★★★ Michael C · Feb 21, 2026

I’ve used this for a few years now, and it’s just what I needed. I really enjoy being able to easily adjust the CAPTCHA difficulty on individual alarms, especially when I know I'll need a bit more 'motivation' to wake up for one.

Sheep are cute now. Harder to spot the sleeping one at an angle in the morning light, maybe I need curtains

★★☆☆☆ Matt Zimel · Apr 2, 2024

The ideas are there, for sure. But the UI? So strange! Every other alarm clock app works normally: You toggle different "captchas" on/off, and can preview and adjust settings for each. But here? You have to select multicaptcha as your captcha, then navigate to a new [unintuitive] screen to choose the other captchas, that you can't preview or adjust settings on. So, you either go back to the beginning and try each one manually, or you keep selecting & deselecting and previewing. Just plain weird.

Some captchas work, some don't. The backwards quote one is stuck on saying getting a quote from the internet, and it never actually pulls a quote
