I love tracking time with Toggl! I also love to set weekly and monthly goals for important activities like coding or learning a new language. I wanted to see my daily, weekly and monthly progress towards these goals, so I've created Hours app. THIS APP ONLY WORKS IF YOU HAVE A TOGGL ACCOUNT You could create goals for specific clients or projects and set time goals for days, weeks and months. Weekly and monthly goals could be calculated based on daily goals or you could set them manually. You could start timers for a particular goal by tapping on it - timers you've used most this week will be shown immediately, other timers are just one tap away. This app is made to improve your current results, so you could see results only for current periods. Results for previous periods you could find on Toggl site. I hope Hours app will help you achieve all your time goals!

Sol Clock is a solar time clock connecting you to the rhythm of the sun and moon. Sol Clock shows you where the sun actually is, from nautical dawn through solar noon to deep night. Displayed on a beautifully crafted astronomical clock face inspired by medieval clocks of Venice and Prague. Sol Clock displays true solar time alongside standard and UTC, so you always know where you stand in the actual solar day, not just the civil one. The Clock The clock face renders a full 24-hour solar day. The hand tracks the sun's position through the light spectrum of the day. The orbital ring shows the complete sky color spectrum for the day. Computed dynamically based on your location and the day's sunrise and sunset times. Sky Map The Sky Map shows an equidistant northern projection centered on the North Pole with a live terminator line showing the boundary between day and night. Solar Compass The Solar Compass tracks the sun and moon in real time and shows their current relationship to the Equator and Tropics of Cancer and Capricorn. Planisphere An interactive star and planet finder for the naked-eye sky. Roll through and highlight 37 constellations by name, or browse all eight planets at once, each shown at its true position. Naked-eye planets are set apart from the outer planets, which are included for reference. Polaris is always marked, so you always have a fixed point to orient yourself by. Events & Alarms Enable notifications for any point in the solar day: Nautical Dawn, Civil Dawn, Sunrise, Golden Hour End, Morning Light, Solar Noon, Afternoon Light, Golden Dusk, Sunset, Civil Dusk, Nautical Dusk, and Night. Each alarm fires at its precise solar time for your location, rescheduling automatically every day. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
