I just started making soap last month. I cannot even begin to know how to use soapcalc. This made the process of creating a soap recipe easy and fun. With the added inventory function, I’ll be able to track everything I use. -- Celeste Brewer, 2026-02-28 [View all Soaper reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Soaper In-App Purchases | Item | Price | |------|-------| | Soaper Premium | $2.99 | ## Soaper Available In - [United States](https://apptail.io/app/soaper-soap-calculator-KYFy/united-states) - [New Zealand](https://apptail.io/app/soaper-soap-calculator-KYFy/new-zealand) - [Chile](https://apptail.io/app/soaper-soap-calculator-KYFy/chile) - [China](https://apptail.io/app/soaper-soap-calculator-KYFy/china) - [Ecuador](https://apptail.io/app/soaper-soap-calculator-KYFy/ecuador) - [Spain](https://apptail.io/app/soaper-soap-calculator-KYFy/spain) - [Hong Kong SAR China](https://apptail.io/app/soaper-soap-calculator-KYFy/hong-kong) - [Paraguay](https://apptail.io/app/soaper-soap-calculator-KYFy/paraguay) - [Taiwan](https://apptail.io/app/soaper-soap-calculator-KYFy/taiwan) - [Australia](https://apptail.io/app/soaper-soap-calculator-KYFy/australia) - [Vietnam](https://apptail.io/app/soaper-soap-calculator-KYFy/vietnam) - [Brazil](https://apptail.io/app/soaper-soap-calculator-KYFy/brazil) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
