Tizen Developers

Hello,

I did not find any default weather app in tizen. But In my opinion, you can use any available Weather API. You can see this post as useful: https://developer.tizen.org/ko/forums/web-application-development/free-weather-and-forecast-api-tizen-applications

And I have tested one sample and sharing with you in below:

var canvas, ctx, clockRadius, isAmbientMode, temparature;

window.requestAnimationFrame = window.requestAnimationFrame ||
    window.webkitRequestAnimationFrame ||
    window.mozRequestAnimationFrame ||
    window.oRequestAnimationFrame ||
    window.msRequestAnimationFrame ||
    function(callback) {
        'use strict';
        window.setTimeout(callback, 1000 / 60);
    };

function renderDots() {
    'use strict';

    var dx = 0,
        dy = 0,
        i = 1,
        angle = null;

    ctx.save();

    // Assigns the clock creation location in the middle of the canvas
    ctx.translate(canvas.width / 2, canvas.height / 2);

    // Assign the style of the number which will be applied to the clock plate
    ctx.beginPath();

    ctx.fillStyle = '#999999';

    // Create 4 dots in a circle
    for (i = 1; i <= 4; i++) {
        angle = (i - 3) * (Math.PI * 2) / 4;
        dx = clockRadius * 0.9 * Math.cos(angle);
        dy = clockRadius * 0.9 * Math.sin(angle);

        ctx.arc(dx, dy, 3, 0, 2 * Math.PI, false);
        ctx.fill();
    }
    ctx.closePath();

    // Render center dot
    ctx.beginPath();

    ctx.fillStyle = '#ff9000';
    ctx.strokeStyle = '#fff';
    ctx.lineWidth = 4;

    ctx.arc(0, 0, 7, 0, 2 * Math.PI, false);
    ctx.fill();
    ctx.stroke();
    ctx.closePath();
}

function renderAmbientDots() {
    'use strict';

    ctx.save();

    // Assigns the clock creation location in the middle of the canvas
    ctx.translate(canvas.width / 2, canvas.height / 2);

    // Render center dot
    ctx.beginPath();

    ctx.fillStyle = '#000000';
    ctx.strokeStyle = '#fff';
    ctx.lineWidth = 4;

    ctx.arc(0, 0, 7, 0, 2 * Math.PI, false);
    ctx.fill();
    ctx.stroke();
    ctx.closePath();
    ctx.fillText(temparature,canvas.width/2, canvas.height/2);
}

function renderNeedle(angle, radius) {
    'use strict';
    ctx.save();
    ctx.rotate(angle);
    ctx.beginPath();
    ctx.lineWidth = 4;
    ctx.strokeStyle = '#fff';
    ctx.moveTo(6, 0);
    ctx.lineTo(radius, 0);
    ctx.closePath();
    ctx.stroke();
    ctx.closePath();
    ctx.restore();
    ctx.fillText(temparature,canvas.width/2, canvas.height/2);

}

function renderHourNeedle(hour) {
    'use strict';

    var angle = null,
        radius = null;

    angle = (hour - 3) * (Math.PI * 2) / 12;
    radius = clockRadius * 0.55;
    renderNeedle(angle, radius);
    ctx.fillText(temparature,canvas.width/2, canvas.height/2);
}

function renderMinuteNeedle(minute) {
    'use strict';

    var angle = null,
        radius = null;

    angle = (minute - 15) * (Math.PI * 2) / 60;
    radius = clockRadius * 0.75;
    renderNeedle(angle, radius);
    ctx.fillText(temparature,canvas.width/2, canvas.height/2);
}
