Pennygrove makes a no-buy or low-buy challenge visual: each daily check-in helps a plant grow, and milestones unlock more plants for a personal garden. Users choose what they are trying to skip, record whether they avoided that purchase, and can optionally enter the amount they would have spent. A calendar, streaks, savings total, home-screen widget, and share cards help make progress visible. The app says it does not require an account or bank login, and check-ins are stored on the device; inviting friends shares progress with them. Pennygrove is free with occasional ads. The US App Store lists a $4.99 one-time purchase to remove ads and a $2.99 watercolor plant pack. It is a habit aid rather than an automated budget or bank-connected finance tracker.
