Intervallical is a simple to use countdown timer with three distinct modes of operation: Simultaneous, Consecutive, and Intervallic. Simultaneous mode starts the two user-defined timers at the same moment, and then notifies the user when each of the two reached zero. Consecutive mode works similarly to the Simultaneous mode, but the difference is that the second timer fires off after the first one hits zero. This is a take on the classic „Pomodoro” timer, in which a 25-minute study session is followed by a 15-minute break to „recharge the batteries” before another 25-minute session takes place. The third, and the last mode of operation, is the Intervallic mode, which may seem a little peculiar, but adds a different flavour into the mix. The way it works is that the user defines a specific time interval for the second timer to start. Say that the user set the first timer for 4 minutes and the second for 6 minutes, with the interval in-between being set for 1 minute. The second timer, which was initially set for 6 minutes, will fire only when the first timer will reach 3 minutes. That way the countdown for the second timer can be „delayed” by the user-specified interval. The app was built so that it is easy to use, with controls (and UI) that are familiar to iOS users. Simply add a new card, which contains your predefined timers, and you are ready to go. Start the countdown by tapping the middle of the circle, tap once again to pause, and tap twice to reset the timers. That’s all there is to it.

Amplify your sentiment to maximize your potentials! Practicing the awareness of your sentiment is an important life skill. Recording and sharing your sentiment for your own review over time as well as sharing your sentiment with others improve your leadership goals and team work successes. If you find yourself resonating with the above, and you also appreciate natural & elegant designs, Los OSOs is the App for you. Some Frequently Asked Questions (FAQs) to orient you better: (1) How can I conceptualize the Los OSOs App? Think of your Los OSOs App as your sentiment GPS. (2) What is unique about Los OSOs in terms of recording sentiment? Importantly, Los OSOs offers a way to record and share your sentiment without involving language (i.e., words) (see FAQs #6 & #6 below for more about the OSO-Pearl technology). Los OSOs is designed to be easy to use, quick, and elegant. (3) Where does the name OSO come from? Our app and technology is affectionately named OSO, meaning bear in Spanish and pays tribute to Cloudbear - our Great Pyrenees dog and beloved family member and livestock guardian - known for his boundless love and vigilance against predators. Our Spanish speaking friends call Cloudbear “oso” given his striking resemblance to a polar bear. Cloudbear has a big heart, he readily shares his sentiment constantly, so it is very fitting that our OSO Apps are named after him. (4) What is the technology behind the Los OSOs App? The Los OSOs App is powered by the new and proprietary OSO-Pearl technology from the KRONxArc / Nectelier Team. (5) How does the OSO-Pearl Technology work? Touch the OSO-Pearl interactive area to record your emotion in 3 dimensions: x, y, and z, for happiness (H), energy (E), and assuredness (A), respectively. For example, if you feel happy, your OSO Mark would be on the right half of the OSO-Pearl because that's the "+" side of the x-axis; if you feel your energy is elevated, your OSO Mark would be on the top half of the OSO-Pearl because that's the "+" side of the y-axis; if you're very sure about how you feel, tap multiple times to mark your OSO to express your certainty - this increases your assuredness which is the z-axis value. (6) What is the lexicon of the Los OSOs App? When using the Los OSOs App, we think of the word 'OSO' as a noun, verb, or an adjective. For example, capturing a sentiment with the Los OSOs App can be described as creating an OSO. The action of engaging with the App is called OSO-ing. The OSO also refers to the interactive area that resembles a pearl. Your creation, i.e., the OSO-Pearl with the "OSO Mark" that you'll have marked is called your OSO. Imagine thinking or asking "How's your OSO?" as a way to show you care and recording your sentiment. When a topic or subject (words, phrase, image, etc.) has been OSO'ed by someone, it shows this subject is worthy of being OSO'ed and worthy of the user's time and efforts. (7) What's the difference between Los OSOs App and OSO+ App? Los OSOs App is designed to be shared with your team and the community to improve team work, leadership, and business product ratings type applications. OSO+ App (a sister-app in the OSO App family) is designed primarily for private personal use. (8) How about my data privacy? The Los OSOs App is designed for sharing your sentiments. Importantly, your data is not linked to you, so your anonymity is maintained. When you OSO with the Los OSOs App, the data is shared with our database. (9) Where can I find App Terms of Use, Privacy Policy, Tutorials and more? We follow the Apple standard Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Check out our website http://www.kronarc.com/oso for more as well as links on our website to video tutorials our team has created.
