A lovely day for you. A hot one underfoot for them.

Asphalt 50℃ 122℉ How hot it is for bare paws

Osanpo Biyori looks past the temperature. Pavement heat, humidity, wind and UV all go into one answer to “Is it okay to go out now?”, ready for you every morning.

Today's Walk Index

Temperature, humidity, rain, wind and pavement heat add up to one score from 0 to 100 for how good a walk would be right now. You also get an hourly index and a suggested walk time, so one look in the morning is enough to plan the day. Temperatures show in ℃ or ℉, following your phone's settings.

  • Walk Index by hour from 11:00 to 15:00, with cards for heatstroke, pavement temperature, air pressure, dryness, UV and shedding season below

Why that score? We show our work

See the score broken down into seven factors: heat, pavement, rain, cold, wind, UV and dryness. The reasoning and the sources are in the app too, so you can check them for yourself instead of taking our word for it.

  • Score breakdown screen: 100, perfect for a walk, with all seven factors rated good
    A 100-point day
  • Score breakdown screen: 10, best to stay in, with heat and humidity marked in red as the main factor

Hot pavement and heatstroke risk

Osanpo Biyori estimates how hot the asphalt gets from the height of the sun, the clouds and the rain, and tells you which hours may be hard on paw pads. Heatstroke risk follows the heat index bands of Japan's Ministry of the Environment, and flat-faced breeds, puppies and seniors are judged more cautiously.

The week ahead, at a glance

Same weather, a different answer for each dog.

Dogs with short muzzles can't shed heat easily. Small dogs close to the ground take the full heat coming off the pavement. A thick double coat and a short coat that feels the cold make for very different comfortable days. Osanpo Biyori builds those differences into every answer.

Osanpo Biyori Premium

The core features stay free. For a little more help, Premium adds these six.

  • Family sharing

    Keep your pup's records in one place for the whole family

    Family sharing screen with Mom's iPhone and Dad's Android listed as members, and an Invite family button below

    Sync weight, care logs and the Memory Map with your family's devices. Just send an invite code, iPhone or Android. One subscription is enough: invited family members (up to 5 devices) join free and can use Calendar, Memory Map and Coat colors too.

  • Coat colors

    A mascot in your pup's coat color

    Coat color screen with a Cairn Terrier mascot in four coats: wheaten, brindle, gray and red, with red selected

    Pick the color closest to your pup from the coats we've drawn for each breed. Home and widgets show the color you pick, and family members in Family sharing see the same coat. If the color or the ears don't match your pup, you can send us a request.

  • Calendar

    Your pup's plans, on the calendar your way

    Calendar screen for September with care plans such as vaccines, medicine and grooming marked as colored dots

    Add whatever your dog needs, from grooming and vet visits to heartworm prevention, and keep a record of each with photos and notes. Vaccination and flea and tick plans are free even without Premium.

  • Memory Map

    Keep walk memories on the map, with photos

  • Pressure graph

    Pressure changes, graphed 3 days ahead

    Pressure graph screen. Today's pressure line starts falling at 6 PM and the falling hours are shaded, with a “10 PM 1012 hPa” bubble and a frowning face marker

    See the pressure trend for today, tomorrow and the day after as an hourly line. Falling periods are shaded, and you can see when things change, like “Falls from 9 PM.” The free version still shows the current pressure level (three levels) on the Home card.

Frequently asked questions

Can I use the app without allowing location access?

Yes. Register a location from the location menu on the Home screen and you can use every feature.

Is the pavement temperature an actual measurement?

No. It's an estimated guide based on the height of the sun and the cloud cover. Before you head out, use it together with the 5-second check: place your hand on the ground for five seconds.

Does it work outside Japan?

Yes. Everything works wherever you are, except the rain radar, real-time alerts, weather warnings and observed current temperature. Those use data from the Japan Meteorological Agency and cover locations in Japan only.

Can I keep using the app for free?

Yes. The Walk Index, heatstroke and pavement temperature ratings, the weekly forecast and more are free. The care calendar is free too for plans such as vaccinations and flea and tick prevention. Osanpo Biyori Premium is an optional plan that adds to all of this.

Is Osanpo Biyori Premium available on Android too?

Yes. You can subscribe on either iOS or Android. The core features are free on both.

Does everyone in the family need to subscribe to share?

No. Only the one device that starts Family sharing needs Osanpo Biyori Premium. Family members who join with an invite code (up to 5 devices) join for free, and you can share between iPhone and Android, too.
