About

ShoeKeep

Features
Read full description

When did you last polish those leather shoes? ShoeKeep is a reminder app that manages the care and rotation of your leather shoes. Just register your shoes, and it figures out when to polish them — from how many times you've worn them and the days since your last care. We remind you before care is due, and gently nudge you until you polish, even if the date has passed. No more shoes left in the cabinet until they crack. ■ Who it's for - You want to keep your leather shoes for years - You catch yourself wearing the same pair over and over - You always miss the right time to care for them - You want a clear view of the shoes in your cabinet ■ Features - Auto-calculated "time to polish" from material × wears and days (built-in guidelines for smooth leather, cordovan, suede, and more) - Rotation view showing which shoes are ready today vs. resting (don't wear the same pair daily) - Three-stage notifications (ahead of time, on the day, then daily until you polish) - Add photos of your shoes (background removed automatically) - Material-specific care tips - Group by cabinet or storage spot (Premium) - Care records and "shoes to polish soon" alerts (Premium) - Home screen widget showing your next care timing at a glance - A fresh leather-shoe tip every day ■ Free vs Premium The free version lets you track up to 3 pairs. Premium (one-time or weekly) unlocks unlimited shoes, grouping by cabinet, care records, and removes ads. ■ Note Care intervals and rest days are general estimates based on material. Please adjust to the actual condition of your leather. ■ LINKS - Support / Contact: https://tsuzukit.com/contact/ - Terms of Service: https://tsuzukit.com/legal/terms-of-service.html - Privacy Policy: https://tsuzukit.com/legal/privacy-policy.html
