About Check Calendar
Check Calendar is a productivity app from developer Naoki Otsu, shipped under the package name com.checkcalendarapp. It is built for people who want a calendar-focused tool on their device instead of a bloated all-in-one suite. What Check Calendar Puts In Front Of You As its name suggests, the app centres on keeping a calendar close at hand, and it sits squarely in the productivity category. Rather than stretching across unrelated tasks, the focus stays on the schedule itself, so the workflow revolves around dates, plans and the ordering of your day. A Build That Keeps Moving The latest release is version 14.49.0, published 2026-10-03. The four-part version number shows a product that is actively maintained rather than left to stagnate, and users who install updates will always be running the current build listed here rather than an older one. Device And Storage Considerations The build requires the minimum Android version specified in this listing, and newer devices will run it without issue. The package weighs 100.6 MB, which is a noticeable but reasonable footprint for a productivity app, so it is worth having a little free space available before you begin the installation. Who This App Suits Check Calendar suits anyone who prefers one clear purpose over a crowded toolbox: managing a calendar without distractions. Because it comes from an individual developer rather than a large studio, the product reads as a focused, personal piece of software aimed squarely at day-to-day planning.
