But will be wonderful if calculation progress with formulas and graphics added on separate page for compass error and celestial navigation for practical purpose or for keeping records -- Mykola828283992, 2025-01-24 ### ***** "Программа отпад" Программа супер, пользуюсь уже 2,5 года. Но вот не хватает функции изменения девиации. Разраб по братски добавь эту функцию -- Kirk_ro, 2025-01-07 ### ***** "Variation" Спасибо вам за ваш труд! Раньше если я сам внес склонение то при смене данных гирокомпаса или МК магнитное склонение осталось неизменным сейчас при вводе данных ГК или МК оно меняется, и это не удобно! -- Kakandjopa, 2024-09-27 ### ***** "Супер" Спасибо большое разработчикам !!!) -- vasabivasyaaaa, 2024-09-01 ### ***** "Про програму" Хороша програма, дякуючи їй, швидко можна знайти поправку на компас. Поки більше користуюсь саме цією функцією. Ла Port LoCode. Але хочу запропонувати також калькуляцію squat. Було б непогано. -- speedyGonzales 2233, 2024-02-29 ### ***** "Best of a kind" Приложение топ 👍 Отличный карманный помощник в навигационных делах. Почаще бы обновления и новые фичи 👌 Некоторые порты из UN Locode имею старые названия. -- Yevgenio, 2024-02-03 ### ***** "Squat and UKC calculations" 👋 Can you add squad and UKC calculator? -- Віктор Чикун, 2023-08-09 ### ***** "Celestial Observation" Should we expect to be able to print the final report? -- krash121, 2023-08-05 ### ***** "Лучший!" Это просто идеальнейшее приложение - из косяков - в журнал не переписывает поправку, но думаю в будущем пофиксят😂, а пока использую приложение палубный кадет) тоже ничего)) -- сосллмолвоок, 2023-07-12 ### ***** "Celestial Navigation" Hello ! First of all thank you very much for this app ! But pls can you make that I can print final Celestial report with all 3 LOP and lines , psn and other information same as in compass error report . Thank you -- Allllexxx123432, 2023-07-11 ### ***** "Best App" Never write any reviews, but this app is the best app i ever saw. Awesome design, awesome functions, very helpful for deck officers. Gyro error with magic button “logbook” 🫡 Few days ago was thinking about true wind..Now i saw update and surprised. All the best to developer! -- whotheend, 2023-02-27 ### ***** "App" Very nice app. I will recommend. Pls. add the ability to have a height on the luminaries. -- Sl084, 2023-01-16 ### ***** "Good app" Спасибо разработчику за программу, в ней не только можно посчитать склонение, но и есть un cod, и единицы измерения.очень хороший интерфейс. И ко всему еще такая доступная цена. -- Rammka, 2022-11-01 ### ***** "Igor4854" Very easy in use. Very nice program. Thanks -- Igor 4854, 2022-09-14 ### ***** "Nice" Great UI UX. I’m like a boss on the bridge compared to other officers. -- Bird•, 2022-09-11 ### ***** "Полезное приложение" Спасибо разроботчикам, это то что давно нужно было кому-то сделать, экономит время 👌 -- катаринова, 2022-09-09 ### ****- "Useful" Удобная программа,но нужно выставлять данные под свою девиацию,иначе будут несовпадения с таблицей . -- PureWaterfall, 2021-11-23 ### ***** "Спасибо" Спасибо за приложение оно просто отличное! Просьба добавить фильтр на visible bodies чтобы учитывая только видимые светила программа убирала невидимые. -- MaslenikovR, 2021-10-24 ### ***** "Problem with courses" Really helpful app,but after last update courses variously changing all the time and possible even insert manually cause it’s continuing to change.Can you fix it pls? not useable for moment(( -- Vasyan19921092, 2021-10-11 ### ****- "Discrepancy in calculation" An app is quite good but calculates a true bearing with one day discrepancy. E.g., if you want correct calculations on September 2 you have to choose September 3 in calculation blank. -- iamvli, 2021-09-11 [View all CoNav reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## CoNav Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Indonesia | Navigation | #1 | | Top Paid | Philippines | Navigation | #1 | | Top Paid | Ukraine | Navigation | #3 | | Top Paid | India | Navigation | #4 | | Top Paid | Poland | Navigation | #4 | | Top Paid | South Africa | Navigation | #4 | | Top Paid | Greece | Navigation | #5 | | Top Paid | Brazil | Navigation | #6 | | Top Paid | Mexico | Navigation | #7 | | Top Paid | Egypt | Navigation | #8 | | Top Paid | Türkiye | Navigation | #9 | | Top Paid | United Arab Emirates | Navigation | #9 | | Top Paid | Nigeria | Navigation | #11 | | Top Paid | Indonesia | Overall | #12 | | Top Grossing | Philippines | Navigation | #14 | | Top Paid | Malaysia | Navigation | #18 | | Top Paid | Philippines | Overall | #18 | | Top Paid | Vietnam | Navigation | #19 | | Top Paid | Azerbaijan | Navigation | #21 | | Top Paid | Romania | Navigation | #22 | | Top Paid | Australia | Navigation | #25 | | Top Paid | Thailand | Navigation | #26 | | Top Grossing | Indonesia | Navigation | #28 | | Top Grossing | India | Navigation | #29 | | Top Paid | Peru | Navigation | #32 | | Top Paid | Kazakhstan | Navigation | #34 | | Top Paid | Ukraine | Overall | #34 | | Top Paid | Algeria | Navigation | #35 | | Top Paid | Pakistan | Navigation | #35 | | Top Paid | Russia | Navigation | #37 | | Top Grossing | Ukraine | Navigation | #40 | | Top Grossing | Peru | Navigation | #41 | | Top Paid | Hong Kong SAR China | Navigation | #45 | | Top Paid | South Korea | Navigation | #47 | | Top Grossing | Greece | Navigation | #49 | | Top Paid | United Kingdom | Navigation | #50 | | Top Paid | Singapore | Navigation | #52 | | Top Paid | Taiwan | Navigation | #54 | | Top Paid | Saudi Arabia | Navigation | #58 | | Top Grossing | South Korea | Navigation | #61 | | Top Paid | Greece | Overall | #64 | | Top Paid | India | Overall | #65 | | Top Grossing | South Africa | Navigation | #68 | | Top Grossing | Nigeria | Navigation | #72 | | Top Paid | Lebanon | Navigation | #73 | | Top Paid | Poland | Overall | #76 | | Top Paid | Portugal | Navigation | #77 | | Top Paid | Ireland | Navigation | #78 | | Top Grossing | Mexico | Navigation | #82 | | Top Grossing | Malaysia | Navigation | #83 | | Top Grossing | Egypt | Navigation | #84 | | Top Paid | Colombia | Navigation | #84 | | Top Grossing | Hong Kong SAR China | Navigation | #86 | | Top Grossing | Brazil | Navigation | #91 | | Top Grossing | Poland | Navigation | #95 | | Top Paid | Italy | Navigation | #96 | | Top Paid | Finland | Navigation | #99 | | Top Grossing | United Arab Emirates | Navigation | #100 | | Top Paid | South Africa | Overall | #106 | | Top Paid | Ecuador | Navigation | #108 | | Top Paid | Sweden | Navigation | #112 | | Top Paid | Spain | Navigation | #130 | | Top Paid | Netherlands | Navigation | #132 | | Top Paid | Brazil | Overall | #136 | | Top Paid | China | Navigation | #140 | | Top Paid | Norway | Navigation | #141 | | Top Paid | New Zealand | Navigation | #144 | | Top Paid | Japan | Navigation | #168 | | Top Paid | Argentina | Navigation | #170 | | Top Paid | Mexico | Overall | #182 | | Top Paid | Denmark | Navigation | #183 | | Top Paid | Belgium | Navigation | #183 | | Top Paid | Canada | Navigation | #185 | | Top Paid | United Arab Emirates | Overall | #196 | | Top Paid | Kuwait | Navigation | #222 | | Top Paid | Türkiye | Overall | #225 | | Top Paid | Czechia | Navigation | #226 | | Top Paid | Germany | Navigation | #232 | | Top Paid | France | Navigation | #242 | | Top Paid | Egypt | Overall | #284 | | Top Paid | Chile | Navigation | #310 | | Top Paid | Austria | Navigation | #332 | | Top Paid | United States | Navigation | #336 | | Top Paid | Hungary | Navigation | #351 | | Top Paid | Israel | Navigation | #364 | | Top Paid | Romania | Overall | #403 | ## Apps Similar to CoNav -
