About

Instant Zmanim

Features
Read full description

There are some excellent and very well-made Zmanim apps out there that have lots of features and special customizations. This app is not one of them. Instead, it aims to be able to quickly get a glimpse of the daily zmanim for the area. As of this first release, please be warned that the zmanim have not been verified and should be treated as approximate times. This app should not be relied upon for exact halachic times. Please confirm these times with another more well established zmanim calculator, or check the times of your local community. There are plans to improve accuracy and verify in the future.

KosherChat is a capable AI assistant built for Jewish life β€” with a thorough kosher content filter and thoughtful support for the rhythm of your week. Ask questions, draft messages, do deep research, attach photos, and keep your conversations and memory in one place on iPhone and iPad. WHAT YOU CAN DO β€’ Chat with a capable AI β€” everyday questions, writing help, research, and more β€’ Get Shabbos times (zmanim) and weather based on your location β€’ Set reminders and view tasks in Today β€’ Attach photos and files from chat β€’ Save Artifacts from your conversations β€” code, documents, and previews in one place β€’ Install Skills β€” reusable instructions for tasks like email drafts, Shabbos planning, or research β€’ Create custom Skills with AI (paid plans) β€’ Connect Tether to run tasks on your computer from your phone (Pro) β€’ Optional Google integrations on Pro β€” Gmail, Drive, Calendar β€’ AI instrumental song generation on Pro plans KOSHER BY DESIGN β€” NOT JUST IN NAME Most AI assistants have no guardrails. KosherChat is different. Advanced built-in content filters block inappropriate, explicit, and offensive material by default β€” no settings to toggle, no loopholes. It’s an assistant you can open without hesitation, in any context, around anyone. BUILT FOR JEWISH LIFE KosherChat understands the rhythm of your week β€” candle lighting times, zmanim, Shabbos planning, and halachic questions answered in plain language with real sources. One thing we take seriously: KosherChat will never pasken. When you ask a halachic question, it brings down the relevant sources β€” Shulchan Aruch, Mishnah Berurah, poskim β€” explains the considerations clearly, and directs you to ask a qualified Rav for a final ruling. That’s not a limitation. That’s the point. An AI has no business paskening, and ours never will. PLANS β€’ Free β€” generous daily chat limits, no credit card required β€’ Pro β€” $29.99/month: more access, premium models, Google apps, Tether, and optional extra credits β€’ Pay as you go β€” buy credits when you need them; credits never expire Subscriptions and credit packs on iOS are purchased through the App Store. Restore purchases anytime from Account β†’ Billing. PRIVATE BY DESIGN Your conversations are between you and KosherChat β€” not a public social feed. Notifications and location are optional and help with reminders and zmanim; the app explains each before iOS asks. You can delete your account anytime from the app. KosherChat provides informational assistance only β€” not professional rabbinic, medical, or legal advice. For halachic decisions, always consult a qualified Rav. Privacy Policy: https://www.kosherchatai.com/web/privacy Terms of Service: https://www.kosherchatai.com/web/terms
