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.

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

Easy & phenomenal

3rd review April 2024. Great app and after several years, I am still using it to gain perspective and increase my understanding. 2nd review 2021. It is hard to explain how great this app is. On my first review more than a year ago, I thought it was phenomenal. After longer experience, I find it even better. Wow! I like the way I can compare sizes, eg, a whale shark and an African elephant. Try it on Apple TV on a big screen TV for an even better appreciation of the immense variation of sizes. This app gives one an appreciation for the scale of the universe from the tiniest particles to the largest immensity.
