Never get caught flat and dry.
Tubeless sealant dries out while your bike sits in the garage — and you usually find out the hard way. Sealr reminds you to top up before it does, across every bike and wheelset you own.
No account. No tracking. Your data stays on your iPhone.
Everything you need, nothing you don't
Sealr does one job and does it well: keeps your tubeless tyres ready to ride.
Reminders before it dries
Get a nudge while there's still sealant to top up — not after you're stranded with a flat that won't seal.
One-tap logging
Log a top-up or full refresh in a single tap. Your next reminder resets itself automatically — no maths.
Every bike & wheelset
Road, gravel, MTB, plus spare wheelsets. Track every tubeless setup you own in one tidy garage.
Know what you used
Record the sealant brand and exactly how much you added, in ml or oz — no guessing, no cross-contamination.
Set your routine once
Pick a top-up interval and a full-refresh cadence that suit your climate and riding. Sealr handles the rest.
Private by design
No account, no sign-up, no analytics SDKs. Everything lives on your device and never leaves it.
Set it up once, ride worry-free
Three steps and you'll never have to remember a re-seal date again.
Add your bikes
Add each bike or wheelset, set the sealant you run, and pick how often it needs a top-up.
Get reminded
Sealr schedules a local reminder for each setup and tells you, at a glance, what's due.
Log & repeat
Top up, tap to log it, and the next reminder resets automatically. Done.
Set your routine once
Your whole garage, at a glance
Track what you used
Keep your tyres ready to ride.
One gravel bike or a garage full of wheelsets — Sealr keeps you topped up.
