Mobility tracking
Dog Mobility Tracker for Everyday Movement
Record whether movement felt normal, slower or difficult and keep that observation beside walks, comfort, medication and weight.
Direct answer: Buddylio is a dog health tracking app with a daily mobility check in on iPhone and Android. It helps owners record movement changes but does not identify their medical cause.
Completely free: Every feature is included, with no ads, subscriptions, paid tiers, trials or locked tools.

What to record
Use plain observations: getting up, using stairs, walking pace, willingness to move and recovery after activity. Avoid guessing at the cause in the log.
Why a daily baseline helps
A single slower day may be easy to forget. Several dated observations can help you explain the pattern more clearly to your veterinarian.
Use the tracker responsibly
Sudden inability to stand, severe pain, collapse or breathing difficulty needs prompt veterinary attention. An app is not an emergency service.
Where this guidance comes from
The urgent signs named above are not a judgement call this app makes. These are the veterinary sources behind them.
