Можно каждый раз рисовать и "вычеркивать" день, можно сохранить крест как кастомное изображение и добавлять его через контекстное меню к любой дате (через долгое нажатие) ### 4/5 — Simple, great tool to track *2025-06-09* Use it to track my workout schedule and countdown the days until my vacations. Just wish you didn’t have to pay for it every month! ### 5/5 — Easy to use *2024-08-28, version 2024.5* Easy to use ### 5/5 — Удобный *2024-08-26* Пользовалась этим календарем, когда считала дни до отпуска и увольнения. Удобно, помогало немного скинуть стресс в конце рабочего дня. ### 5/5 — So simple and so effective *2024-08-08* I’ve searched for easy to use ways to visualize my habit consistency and this app not only offers that but also a way to plan future consistency. The week and month and year at a time views are very helpful. ### 5/5 — Great response from app developer *2024-06-25, version 2024.5* I love this app. I work on a hybrid basis and need to record days worked at home and office. This app records it in an easy to see visual and totals each category to easily track my minimum office attendance rate. Experienced some glitches in the app. Developer responded to my initial review and glitches now resolved. Highly recommended. ### 2/5 — Such a shame *2024-05-09, version 2024.3* It’s such a great concept but whenever I view by year everything glitches and goes blank ### 5/5 — ⭐️⭐️⭐️Boundless Functionality!! *2024-05-07* A must have if you are looking to track progress on anything visually! So many options and even stats achieved when tracking Streaks. Easy to use! ### 4/5 — lost all my data *2024-05-02, version 2024.3* i guess the app was updated or something and i lost all the calendars & data i had set up :( update: i was able to get it back by using the backup data ### 5/5 — Very useful calendar *2024-04-05* Good to use to organize activities and work schedule in one calendar! Thanks Mark Off! Just starting to use your multitude features… ### 4/5 — Хорошее приложение *2024-01-24* Все отлично и удобно, на рабочем столе в виджете хотел бы чтобы даты по цвету разметки сразу отмечались. В остальном без минусов , очень доволен **Developer response:** Привет! Спасибо за отзыв. Можешь, пожалуйста, написать mail@viktorgavrilov.com подробнее, что имеется ввиду. Добавлю в следующих версиях ### 5/5 — I had to Erase my phone *2023-12-28* I had to erase my phone and install everything without a backup (backup would bring back the problems I was having). The app has a sync option even in the free version! That saved me big time. Otherwise I would have lost all my data. Thank you for having it sync even in the free version! **Developer response:** Sorry to hear it. The data is also backuped in iCloud. Could you please check, maybe you could still recover it. ICloud sync is included in the free version, as well as local back ups. ### 5/5 — Very convenient *2023-12-22* Suits my needs. 5/5 ### 2/5 — Cool but too many ADS *2023-11-09, version 2023.12* Too much advertisement. The idea is good but the user experience is horrible ### 5/5 — I love this for the N S diet! *2023-09-11, version 2023.9* I’ve tried every diet out there and the most sane normal diet is the NO S diet. It’s just normal eating. This app works the best at tracking easily. Thanks so much for this simple easy app! ## Most critical reviews (10 lowest-rated) ### 1/5 — Paid and widgets don’t work *2026-03-16, version 2025.8* Paid for unlimited and widgets often don’t update or don’t load at all ### 1/5 — Porn pictures *2026-01-16, version 2025.8* It was fine until I have porn advertisements at the top of my screen ### 1/5 — Unable to add widget to Home Screen *2024-02-27, version 2024.1* Unable to add widget to Home Screen ### 1/5 — После обновления пропали все отмеченные дни *2023-02-15* После обновления пропали все отмеченные дни. Доступ у приложения к iCloud имеется. Пробовал переустанавливать приложение, но не помогло, к сожалению. **Developer response:** Дмитрий, спасибо за отзыв. В версии 2023.2 был баг с Базовыми календарями. Все данные/изображения на месте, проблема только с их отображением. Обновление 2023.3 исправляет эту ошибку ### 1/5 — Data wiped *2023-02-15, version 2023.2* App did an update and now all my data has been wiped. ### 1/5 — Deleted all my data suddenly *2023-02-14, version 2023.2* Opened the app one day and all my progress was gone. Only recorded on here so now I’m starting from scratch ### 1/5 — Ужасно *2022-08-12* Через две недели все мои календари исчезли. Потерны все данные, которые я заносила по приему таблеток. Нет слов **Developer response:** Можешь, пожалуйста, проверить есть ли в хранилище iCloud данные для Visual Calendar? Если до сих пор есть данные, то тогда нужно удалить приложение и установить его заново, данные загрузятся после переустановки. Если не поможет, напиши, пожалуйста на почту mail@viktorgavrilov.com ### 1/5 — Бред *2021-06-15* Бред ### 1/5 — ? *2020-04-21, version 2020.5* How do we cross things out? ### 2/5 — If you log each day it froze *2025-08-11, version 2025.8* I was considering to pay for the full version because with this I log my husband's ptsd symptoms. But if you write each day.. The app freezes and it's more difficult to write each time. Please optimize your app!! I really want it to work. ## Most praised reviews (10 highest-rated) ### 5/5 — Just What I was looking for. *2026-06-23* I wanted to quickly visualize my mostly daily workouts in a monthly view. I have a different icon for every activity such as running, cycling, mat workouts, etc., and a custom big red X on days I do not work out. This allows me to quickly see my activity and not miss a workout for more than two days if I don’t want the big Xs to stare back at me. I love all the options for customization and that is why I paid for this app. I am very satisfied and also if I want to add more calendars to track my kids’ stuff, the option is there. **Developer response:** Thank you so much for this. If you ever have ideas or suggestions, feel free to write me directly - I read everything and many features come straight from users ### 5/5 — Just What I was looking for. *2026-05-14, version 2025.8* I wanted to quickly visualize my mostly daily workouts in a monthly view.

( also thank you for not forcing a bunch of useless AI updates into it ) **Developer response:** Thank you, reviews like this honestly make my week. If anything comes to mind - ideas, suggestions, questions - just shoot me an email. I'd love to hear it. ### 5/5 — Супер приложение *2025-11-16* Спасибо за такое продуманное и мотивирующее приложение! ### 5/5 — Amazing *2025-10-11, version 2025.8* Does exactly what I need, please don’t ever change the app too much this is legitimately perfect! ### 5/5 — Nice & Simple habit tracker *2025-07-11, version 2025.8* I wanted something similar to an old school paper calendar where you would track days by simply ticking or crossing them out. This allows me to do this is various fun ways (like using a coloured highlighter). It’s simple, it’s perfect. I love using this to track how often I’m completing new habits like going for a run or remembering to meditate, things like that. It’s so satisfying to give yourself that simple check mark or colour in a box to say you succeeded that day. I love this app. ### 5/5 — Excellent dev *2025-03-11, version 2025.2* The app was working great but missed a feature I really would have liked. I contacted Viktor and within a few days the next update included the feature I enquired about. Thank you! ### 5/5 — Вы лучшие! *2025-03-07* Спасибо за улучшение приложения! Можете, пожалуйста, сделать так, чтобы изменения в виджете сразу обновлялись на рабочем столе. Когда удаляешь отметку на дне, оно сразу обновляется, а если добавить новую, то нужно зайти в виджет 2 раза, чтобы обновилось. **Developer response:** Спасибо за отзыв. Можете, пожалуйста, написать на mail@viktorgavrilov.com, подробее ### 5/5 — Best tracker app and reasonable pricing for premium *2024-11-09* So simple: fill up a calendar with colors that mean whatever you want. No prodding with notifications. No expectation to be overly detailed. Excellent Home Screen widgets. ### 5/5 — A creative DIY loop *2024-10-17, version 2024.5* Concise but not simple --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
