One place to track everything you maintain.
Trend & Tend tracks maintenance for your home, vehicles, and equipment — lawn mowers, snow blowers, HVAC systems, and more — service history, recurring reminders, and costs, all in one place. It's WrinkleByte's flagship product, built by the same small team behind this site.
Everything that needs upkeep, in one app
Homes, vehicles, and equipment don't maintain themselves — and they don't all fit neatly into one category. Trend & Tend doesn't make you pick.
Home, vehicle & equipment tracking
Log service history for your house systems, cars, mowers, snow blowers, generators, and anything else that needs regular care — side by side, not in separate apps.
Reminders that make sense
Set recurring maintenance schedules by time, by usage (miles or hours), or both — so you're reminded based on how the thing is actually used, not just the calendar.
Fuel economy & trip logs
Track fill-ups and mileage, with fuel economy calculated automatically, plus a trip log with photo evidence for every odometer reading.
Costs, all in one place
See what you've actually spent keeping things running, per asset or across everything you own.
Your data stays yours
Trend & Tend works fully offline with no account required. If you want backup or multi-device sync, it connects to a backend you host — we don't operate a hosted copy of your data.
Self-host the backend
The sync backend is open-source and self-hostable with Docker Compose. A published, ready-to-pull container image is coming soon — for now, see the backend repository for the current self-hosting instructions.
