Piggy Challenge-Save Daily

Piggy Challenge is a pocket piggy bank for iPhone and iPad. Open a plan, stamp the day you save, and watch a little pig grow as the jar fills. No account. Your numbers stay on this device.

PLANS
• 365-day method — day n saves n units, or reverse, shuffle, or pick any open cell
• 52-week challenge — week by week, amounts step up
• 12-envelope method — one envelope a month toward a target
• Fixed amount — daily, weekly, or monthly, same sum each time
• Free savings — any amount, any day, toward a goal you name

STAMP & GROW
• Tap today’s cell or log a deposit; the pig changes as you hit milestones
• Calendar grid for 365-day plans so you can see gaps at a glance
• Optional withdraw if you need a little back — the plan stays honest
• Home Screen widgets (small, medium, large) plus Lock Screen glances

BADGES
• Seal stamps for first deposit, streaks, totals, and finished plans
• A quiet achievement shelf — no social feed, no sharing required

PRIVATE BY DESIGN
• Optional daily reminder (notifications)
• Display currency with an optional rate refresh (European Central Bank via Frankfurter)
• JSON backup you save where you choose
• No ads, no in-app purchases, no sign-in

This is a personal tracker, not a bank and not financial advice.
