XII Ivlivs” for 12 days before the Kalends of July. The day, the date, the proverb of the day, and the help text can all be in either English or Latin. You’ll use Latin of course – I’ve just provided the English text for other people who are less erudite than you. For those who seriously want to be Roman, the time can optionally be measured Roman style – still a twenty four hour day, but with the twelve hours of day measured from sunrise to sunset, and the twelve hours of night measured from sunset to sunrise. This way of measuring time has three notable properties; - hours and minutes will be a slightly different length each day, as the seasons pass and the days get shorter or longer. - hours and minutes will be a slightly different length at different latitudes, even on the same day. This is why the app asks you to let it use your location when you’re using Roman style time – it needs it to work out the sunrise and sunset times. - you will never be on time for an appointment again As the help text says: “Sequens programmatiunculum ad Horologium Romanum pertinens conscripsi ut peregrinatoribus qui ab Imperio Romano ad haec tempora iter faciunt auxilio sit. Immo vero etiam aliis lectoribus forsitan utile esse possit.” That is to say – “Horologium Romanum – The Roman Clock app – was written as an aid to time travellers from the Roman Empire who have chosen to visit the 21st century. Even if you do not fall into that group you may still find it useful.” ## Horologium Romanum Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/bd/a4/68/bda46828-2790-73b7-8405-152753aa1dcf/d3b14beb-8840-4a49-9a08-d740e124bac7_portrait.jpg/1242x2688.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/d7/16/32/d7163292-8daa-4945-4d92-e5834b43f036/f9c600c6-6672-4413-98cb-959df753c0ce_landscape.jpg/2688x1242.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/d5/39/50/d539500d-7f36-f3fa-a2f9-5cbe34f48aa2/5e5480cc-4f01-41c6-b9c5-f0b681c90751_portrait1.jpg/1242x2688.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/40/f3/aa/40f3aae8-f6af-19b9-15f3-fcc0526b77d9/dfa0c67b-7813-423a-967f-600ea3797896_portrait2.jpg/1242x2688.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/35/ea/aa/35eaaaa8-567a-3eb0-3bc0-21f415e931da/8d176d7d-06a6-4105-a509-1252633a4c32_portrait3.jpg/1242x2688.png) ## Horologium Romanum Rating Breakdown in United States - 5 stars: 4 (80%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (20%) ## Horologium Romanum Reviews in United States ### *---- "Very Disappointing and Expensive" UPDATE: After viewing a while, the Roman clock is totally whacked. There appears to be no rhyme or reason to the time displayed. ORIGINAL: This seems to be based on the civil clock. I was really hoping the 12-hour option would have the hōra prīma stating at daybreak and nox beginning at sunset. Not that I know all that much about it, per se, but enough to be disappointed. The calendar dates seem, so far, to be spot on, but I could have figured that out myself. The clock is the harder part. This is not worth the price at all. NOTE: It’s also unsupported. -- Paige Markham, 2022-08-29 ### ***** "This is a fun clock!" It’s cool and works great -- Cabbages Yum!, 2020-11-13 ### ***** "Creative way to show time" This is a fun way of displaying time. I have found that the app is good way to force myself to practice Roman Numerals if I want to know the current time. There are also some nice little additions to the clock that have made me learn a few new things, such as what the word "Kalends" means (the first day of the month on the ancient Roman Calendar) Showed it to a friend who is trying to teach Roman Numerals to her daughter and she was pretty excited by this. -- humanclock, 2016-11-30 [View all Horologium Romanum reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to Horologium Romanum - [Smart Home Device [ WiFi ]](https://apptail.io/app/smart-home-device-wifi-kMY/united-states) - [QR Maker & Widget](https://apptail.io/app/qr-maker-widget-mMY/united-states) - [Sakura: Simple & Cute Calendar](https://apptail.io/app/sakura-simple-cute-calendar-Yqjb/united-states) - [Westminster Chimes Full](https://apptail.io/app/westminster-chimes-full-ghMb/united-states) - [LED Clock-Pure Color Clock](https://apptail.io/app/led-clock-pure-color-clock-DeFc/united-states) - [Sankey Finanzflüsse Diagramme](https://apptail.io/app/sankey-finanzflusse-diagramme-ikte/united-states) - [Mahjong Point Calculator](https://apptail.io/app/mahjong-point-calculator-Hgun/united-states) - [PerfectTime.org](https://apptail.io/app/perfecttimeorg-Krpp/united-states) - [Tinker - Watch Face Studio](https://apptail.io/app/tinker-watch-face-studio-fwXu/united-states) - [Atomic Clock: Exact Time](https://apptail.io/app/atomic-clock-exact-time-yDQw/united-states) ## Horologium Romanum Available In - [United States](https://apptail.io/app/horologium-romanum-CFBj/united-states) - [Australia](https://apptail.io/app/horologium-romanum-CFBj/australia) - [Egypt](https://apptail.io/app/horologium-romanum-CFBj/egypt) - [Iceland](https://apptail.io/app/horologium-romanum-CFBj/iceland) - [Malaysia](https://apptail.io/app/horologium-romanum-CFBj/malaysia) - [Norway](https://apptail.io/app/horologium-romanum-CFBj/norway) - [New Zealand](https://apptail.io/app/horologium-romanum-CFBj/new-zealand) - [Saudi Arabia](https://apptail.io/app/horologium-romanum-CFBj/saudi-arabia) - [Singapore](https://apptail.io/app/horologium-romanum-CFBj/singapore) - [Thailand](https://apptail.io/app/horologium-romanum-CFBj/thailand) - [Ukraine](https://apptail.io/app/horologium-romanum-CFBj/ukraine) - [South Africa](https://apptail.io/app/horologium-romanum-CFBj/south-africa) - [Canada](https://apptail.io/app/horologium-romanum-CFBj/canada) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
