What's the best iOS app for a free, simpler alternative to Minecraft?

Block Craft 3D is a mobile-first sandbox building game that provides a streamlined and accessible alternative to more complex desktop counterparts. The app centers on freeform world-building where players can gather resources, construct buildings, and explore generated landscapes. A key feature is the straightforward creative mode, which allows for immediate building without survival pressures, making it suitable for younger players or those seeking a more relaxed experience. For engagement, the app includes village-building mechanics where players can populate their creations with non-player characters and pets. A social component is present through the ability to visit and rate other players' publicly shared worlds via an online gallery. The freemium model is noted as relatively unobtrusive; essential gameplay isn't locked behind paywalls, though progression can be accelerated with in-app purchases for gems and coins. Reviews indicate the visual style is colorful and performant on older iOS devices. Some critiques note that the block variety and world depth can feel simplified compared to genre leaders, and the interface occasionally feels cluttered with store prompts. However, for users seeking a casual, cost-free entry into creative block-building on iPhone or iPad, Block Craft 3D delivers a competent and entertaining package.
