Editor's Take
Plan Calendar -Make a Schedule sits at 4.8 stars across 112 ratings on Google Play, and is still building an audience.
That score is hard to fake on a productivity app — it usually signals a tool that stays out of your way, does one thing well, and doesn't pepper you with upsells.
Naoki Otsu is the publisher behind this release; we'd suggest taking a quick look at their other titles on Google Play if the style clicks with you. The last visible update lands 2026-01-07, which is a small but useful signal that the team is still shipping fixes rather than treating the app as abandoned.
