Recovering Gasaholic ,

Wow! Just wow!

What an amazing app. It’s beautiful, intuitive, packed full of information and so engaging. I spent hours reading just about everything. The range is from the smallest named unit of measurement to the observable universe. I hope updates come with new things to learn about and compare. The music and voice over can be turned on or off (default is on) and you can choose from five accents in English. You can change the text size and units of measurement (imperial, metric or powers of ten). No ads, no in-app purchases, no subscriptions, always a plus. Running iOS 15 and so far, no bugs. I had lots of fun comparing the average woman (about my height) too crazy sizes like zeptometers. I had never heard of a zeptometer, but I have now. If you like learning this is a great app to add to your purchases. I absolutely recommend it.

Developer Response ,

Thank you for such a comprehensive review! 😃 We like zeptometers too! 🥰

Amazing and informative

Beautifully assembled samples and fascinating information presented in such a fun way. My son learned so much from this. I take any opportunity to share science with him.

To the developer: recent findings indicate UY Scuti is not nearly as large as previously thought. Recent discovery also found a new contender, Stephenson 2-18 which is definitely larger anyway. Previous candidate VY Canis Major is also larger. I submitted a link through the app support form.

Amazing learning tool

What a tremendous app this is. Perfect blend of information, usability (coolest zoom/expand feature EVER), and even the background music is perfect for a space information app. I wish you had more users and ratings, because this would be a very popular app if more people knew about it. Thanks for your hard work, and please don’t abandon the app or give up hope—it may take time, but this app’s eventual popularity is worth the wait!
