Honestly, I will never buy another grocery item without this App! Also can analyse my plate and check for healthy ingredients! -- 55Poppy55, 2026-07-22 ### ***** "Changed My Shopping Habits" I’ve been shopping for years and it means nothing to me when I get to the cashier and realize I’m many dollars over my original budget when I walked into the store! Then I started using this app (paid attention to the budgeting module and made a game of it, where I was able to come in with $.50 left on my $80 budget… No overages everything I wanted and I stopped buying garbage! I would’ve never done that until I got this app. Everybody should have it. Cheers. -- HappyCamper923, 2026-07-14 [View all What2Know reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## What2Know In-App Purchases | Item | Price | |------|-------| | What2Know Premium Annual | $19.99 | | What2Know Premium Monthly | $4.99 | ## What2Know Discovered Keywords - what2know ## Apps Similar to What2Know - [Vitality Bowls](https://apptail.io/app/vitality-bowls-eag/canada) - [Maui Happy Hours](https://apptail.io/app/maui-happy-hours-Uyq/canada) - [Fatburger Canada](https://apptail.io/app/fatburger-canada-PBw/canada) - [Breka Bakery & Café](https://apptail.io/app/breka-bakery-cafe-vYUg/canada) - [Presto Pasta](https://apptail.io/app/presto-pasta-Xzem/canada) - [Peach Coffee Co](https://apptail.io/app/peach-coffee-co-yzqo/canada) - [Boomarang Diner](https://apptail.io/app/boomarang-diner-fWAp/canada) - [iQ Food Co.](https://apptail.io/app/iq-food-co-KqIx/canada) - [TailGate Brewery](https://apptail.io/app/tailgate-brewery-qoBA/canada) ## What2Know Available In - [Canada](https://apptail.io/app/what2know-ZUMA/canada) - [United States](https://apptail.io/app/what2know-ZUMA/united-states) --- ## 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.
