I won’t lie, the ui is rough and takes me back to 2008. But the complexity is delightful, I love the modding system, it allows you to really get the most of your towers. If you’re coming for a bloons level game this might not be it, but if you like tower defense give it a shot. -- Eternalsnowfall583, 2026-03-21 [View all Sphere TD reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Sphere TD In-App Purchases | Item | Price | |------|-------| | Defender Starter Pack | $7.99 | | Galatium Express Token | $9.99 | | Galatium Academy Pack | $14.99 | | Flux Enrichment Grant | $24.99 | | Shadow Broker Vantage | $19.99 | | Au Global Reserve | $99.99 | | Au Strategic Stockpile | $49.99 | | Au Enterprise Fund | $24.99 | | Au Supply Cache | $9.99 | | Au Field Ration | $4.99 | ## Sphere TD Available In - [United States](https://apptail.io/app/sphere-td-Lgoy/united-states) - [Canada](https://apptail.io/app/sphere-td-Lgoy/canada) - [Australia](https://apptail.io/app/sphere-td-Lgoy/australia) - [United Kingdom](https://apptail.io/app/sphere-td-Lgoy/united-kingdom) - [New Zealand](https://apptail.io/app/sphere-td-Lgoy/new-zealand) - [Oman](https://apptail.io/app/sphere-td-Lgoy/oman) --- ## 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.
