Ji Calendar is a state-of-the-art, educationally rich, imaginative and enriching series of modules to teach everything that a child needs to know about the Jewish calendar. The app is divided into a classroom tool and an addictive game for students. Students can design their own 'space kid' who will accompany them on their entire journey through the Jewish Calendar. Note: This app will run best on iPad 3 and more devices EXPERIENCE Making this app cross-curricular, are simulations of the astronomy involved with days, months and years. Each simulation displays a window representing what you would see on earth, together with a working 3D model of the solar system, that students and teachers can manipulate to create certain circumstances. There are three modes for each simulation: PLAY – A free play mode that allows the user to manipulate the earth and moon freely to explain how days, months and years work. LEARN –A step-by-step mode that guides the learner from the general astronomical model down to the Jewish application, such as the moon being the basis for the Jewish months. QUESTS – Students have quests that can be answered by manipulating the 3D solar system models. JEWISH CALENDAR At the heart of the product is a calendar tool, which can be used as a classroom tool. Teachers are encouraged to use this tool every day, to discuss today, this month, and this year. The tool demonstrates clearly the overlay of the secular and Jewish calendars. If you have enabled your location settings on your device, then the time shown in the calendar for the zmanim, or times of the Jewish day, will be accurate for your location. TIME CHALLENGE Students will find this game addictive, while being immersed in travelling through time. Major concepts are reinforced, and earning ‘powerups’ involves completing quests in the simulations. Students will run through a Jewish day, learning zmanim, through the Jewish week, learning the connection between Creation and the days of the week culminating in Shabbat, through the month, connecting moon phases with the date in the lunar cycle, and through the year, connecting seasons with Jewish months in Israel. Ji Tap LESSONS on the Calendar The educational content is reinforced with highly interactive educational lessons, built by Ji experts, in Ji Tap. These games are accessible from within the app. RICH EDUCATOR GUIDE Ji Calendar is accompanied by comprehensive educator guides, with rich Jewish content to support the app. COLLABORATION "Ji Calendar" is produced by Jewish Interactive (Ji) and funded by The Center For Initiatives In Jewish Education (CIJE) and the Glatt Charitable Trust.

NOW FREE! Get a free one-year subscription! Just download the app and soon you'll be reading Hebrew...for free! How?! With Eyal. What is Eyal? Eyal is the newest take on an old method. What method? Phonetic decoding. Why phonetic decoding? Because it is a proven and time-tested way of teaching Hebrew reading. For both classical and modern Hebrew texts? Yes and yes. It just works. Self-study, classroom, or anything in between. For over 30 years, the materials on which Eyal is based have been used successfully with students around the world, ages 5 to 98. Now the program has been completely reworked to take advantage of all the iPad can offer. But at its core, Eyal is still a methodical, two-step system: First, you’ll learn the consonants, one at a time. At this stage, the words you’ll be reading will have only consonants and the ‘a’ vowel. Once this has been mastered, you’ll learn the rest of the vowels, also one at a time. Features: - 10 interactive activity types, including Letter Differentiation, Reading, Writing, Matching, Word Search, and more. - Changing study units. Activity types are mixed and matched in different ways as each study unit requires. No two units are exactly the same. - Clear, page-specific instructions. So the app can be worked on alone, not just with a teacher. - Ability to self-check all work. - Ability to tap words and hear them pronounced - nearly 10,000 audio clips are included. - Responsive writing tools and the ability to record yourself reading. - Option to email audio recordings and written answers to teachers for further review. - Modifications for students with learning difficulties or adults who prefer a more straightforward approach. - Account system that allows for multiple users on multiple iPads, with each user’s progress and work saved to their individual account. - No need for internet in the classroom as student work is saved to the iPad itself. - Access to all current and future content and features for as long as your subscription is active. - Ability to add and remove users for as long as your subscription is active. Eyal is appropriate for all ages. Kids who can’t yet read English can now learn how to read Hebrew. Students who have trouble focusing can sit with Eyal for an entire class. And adults who are skeptical of technology are also quick to fall for Eyal. Even those who already know how to read are using Eyal just for review - a tool they can come back to over and over in order to maintain their reading skills. *A note to schools: Eyal can be used in a classroom or resource room as the primary teaching method. Or you can leave your curriculum unchanged and recommend that parents buy Eyal for supplemental at-home use. Eyal is a subscription-based app. Once you select a subscription, your payment will be charged to your iTunes account at confirmation of purchase. Your subscription will automatically renew and your account will be charged for renewal 24 hours before the end of the current period, unless auto-renew is turned off at least 24 hours before the end of the current period. Subscription renewals cost the same as the original subscription. You can manage your subscriptions and turn off auto-renewal by going to your iTunes Account Settings after purchase . Any unused portion of a free trial period, if offered, will be forfeited when you purchases a subscription to that service, where applicable.

Verdict
The clearest difference is in-app purchases: Ji Calendar at none against Eyal's 11. Ji Calendar also leads on iOS requirement (8.0 vs 15.6). Eyal's advantage is update cadence (every 3 days vs every 2 months) and ratings volume (26 vs 2). On price, rating, review sentiment and ads there is nothing between them.
