・A calendar and organizer application with excellent listability! ・You can also sync with Google Calendar via your iPhone calendar! ・ToDo, memo, diary, picture and more! ・The half organizer functions can be viewed simultaneously with the calendar in half-view. ・The "Professional" plan supports 3 month calendar view on iPad and Mac! After 10 years, the successor to the popular "vertical calendar" app for iPhone is finally here! By making the most of the iPhone's large screen, we have achieved an overwhelming amount of functionality. You can change the background color and set the icons so you can visually grasp the schedule. In the day view, events are displayed with checkboxes, so you can manage to-dos on a daily basis. Locations and memos are also displayed, and if a location has been registered, a map can be displayed. Vertical Calendar 2 has the daily planner functions that is optimized for the iPhone's vertical screen. In developing this app, we wanted to incorporate as many of the advantages of a paper daily planner as possible. One of the features of a paper daily planner is that you can look at your schedule while simultaneously viewing your notes or checking your to-dos. We developed the half-view function so that you can see this kind of information other than the schedule at the same time. The daily planner function can be displayed in half-view at the bottom of the calendar, allowing you to check your schedule and to-dos at the same time, just like a paper daily planner. The following functions can be realized as daily planner functions. ・The To-Do List feature allows you to manage To-Dos that are not tied to dates. ・The note function allows you to display the note you always want to see along with the calendar. ・The diary function marks the dates you write in your diary, making it easy to keep a diary. In addition, paper daily planner is highly customizable by allowing you to paste necessary information such as bus schedules and extension numbers. “Vertical Calendar 2” is equipped with an image function to realize such high customizability of the organizer. By taking a picture of the information you need and registering the image, you can check the information immediately, allowing you to access the information as quickly as with a paper daily planner. Of course, you can also check your schedule while looking at your family photos by displaying them in half view. Vertical Calendar 2 also works on iPad and M1 Mac, and supports Slide Over on iPad, which is great for quick schedule checking. If you choose the "Standard" plan, you can use iCloud to sync your data across multiple devices. I hope that "Vertical Calendar 2" will be useful in your life.

Verdict
The clearest difference is ads: Calendars at none against Vertical Planner's shown. Calendars also leads on ratings volume (123K vs 16) and rating (4.7 vs 4.4). Vertical Planner's advantage is iOS requirement (13.0 vs 18.2). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calendars sells 10 in-app purchases, starting at $3.99 per month and Vertical Planner sells 3 in-app purchases, starting at $1.49 per month. Whichever you choose, the download price is not the number that matters.
Calendars holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Calendars has 123K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 56% of Calendars's written reviews are positive against 59% of Vertical Planner's, so the app with the better star average is not the one people write more warmly about.
Calendars ships an update weekly, Vertical Planner fortnightly. The most recent releases landed on November 9, 2026 and November 7, 2026 respectively.
