DueSpare: Home Replacements

Remember what fits your home and when you last changed it.

DueSpare is a focused, offline-first tracker for the replaceable things around your home: filters, batteries, cartridges, brush heads and other consumables you choose to record.

KEEP THE EXACT PART
Save a clear item name, location, model or size, and an optional note. The next time you buy a spare, the detail you need is already where you expect it.

USE YOUR OWN INTERVAL
Record the day you actually changed an item and choose the interval that makes sense for your household. DueSpare calculates the next date from your own entry; it does not prescribe maintenance or safety schedules.

KNOW WHAT IS READY
Mark whether a spare is on hand and scan a calm due-soon view before a shopping trip or a replacement session.

KEEP A USEFUL HISTORY
Completing a replacement adds it to the item's history, so you can look back at what happened without rebuilding the timeline from memory.

PRIVATE BY DESIGN
No account, ads, analytics or cloud backend. Your items, dates and notes stay in the app's private storage on your device. Optional reminders are scheduled locally through Android.

DueSpare is an organization tool, not professional repair, safety, health, energy-saving or manufacturer advice. Always follow the instructions supplied with your equipment and parts.
