Never forget to replace something again. ReplaceHQ is the simple way to keep track of the things you replace, change, service, or refresh on a recurring schedule. Take a picture, let ReplaceHQ identify the item, choose how often you want to replace it, and you’re done. No complicated maintenance plans. No giant checklists. No unnecessary data entry. Snap it Take a photo of the item you want to track. ReplaceHQ can use AI-assisted image analysis to identify the item and fill in useful details for you. Examples include: HVAC air filters refrigerator filters water filters air purifier filters smoke detector batteries toothbrush heads razor blades vacuum filters wiper blades oil changes cabin air filters lawn equipment maintenance and anything else you want to remember Set the schedule Choose how often you want to replace or service the item. Use quick schedules such as 30, 60, or 90 days, or create your own custom interval using days, weeks, months, or years. You can also add an optional location so you always know exactly which item needs attention. Forget about it ReplaceHQ keeps track of the schedule and reminds you when something is coming due. Your Home screen keeps everything organized into simple sections such as: Due now Coming up Later When you replace something, just tap Replaced and ReplaceHQ automatically starts the next cycle. Remember exactly what you need ReplaceHQ keeps the item photo and details with the reminder. That means when it’s time to buy another filter, battery, refill, blade, or other replacement, you can quickly check what you used before.
