Every day you don't spend, your garden grows. Pennygrove turns the no spend challenge into a living garden. Check in once a day, watch your plant grow, and build a streak of skipped purchases you can actually see. HOW IT WORKS 1. Pick what you're skipping — coffee, impulse buys, online shopping, or everything. 2. Check in with one tap each evening. Skipped it today? Your plant grows. Spent? It just waits — progress never resets. 3. Log what you would have spent (optional) and watch your saved total fill the grove. WHAT YOU GET • 1-tap daily check-in — no bank sync, no spreadsheets, no guilt • Streak calendar with a free monthly freeze — and a slip never erases your plant's growth • Your first plant blooms after 5 no-spend days, then joins your grove and a new seed sprouts • Seed collection: unlock 12 plant species as your no-spend days and savings add up — then plant them next • Home Screen widget that keeps your streak in sight • Share cards — post your grove when it blooms • Savings shown in your own currency WHY IT'S DIFFERENT Most no spend trackers are a calendar you mark by hand. Pennygrove gives your self-control a shape: skipped days become growth, milestones become new species, and the money you didn't spend becomes a garden you did. FREE. NO ACCOUNT. NO BANK LOGIN. Your check-ins are stored on your device. No account, no sign-up, no bank connection. If you add friends, your progress is shared with them. The app is free with occasional ads — a single one-time purchase removes them forever. No subscription, ever. (An app about not spending shouldn't bill you monthly.) Start your no buy challenge tonight. Plant the first seed.

Verdict
The clearest difference is ads: Spot Bot at none against Pennygrove's shown. Spot Bot also leads on monetization model (free vs free with in-app purchases) and device support (3 vs 1). Pennygrove's advantage is update cadence (every 5 days vs fortnightly). On price, in-app purchases and iOS requirement there is nothing between them.
