Do you keep a diary? I've tried using various diary apps and paper diaries to see if I could stick with it. But... I couldn't keep it up. Even though I thought, “I should keep a diary! I have to keep one...” I just couldn't make it a habit. That's because... I had to think about what to write. Even if I tried to write at the end of the day, I'd end up thinking, “Huh... what did I even do today?” and using up mental energy just trying to remember. Then, actually writing the diary entry felt like too much trouble. But I still want to keep a record of my days! Well... I have good news for you. This app shows the exact time the moment you press the timestamp button, letting you instantly jot down whatever you want to record. It makes keeping track super easy. It's great for daily journaling, work notes, organizing your thoughts—anything really. You don't even have to press the timestamp button; you can just use it as a memo. And later, when you need to find something, adding tags makes searching a breeze. Plus! It posts to Google Calendar too. So when you wonder, “What did I do that day...?” Or “What was that meeting about last time...?” Just sync everything to Google Calendar, and finding it later is a breeze. ▼ Now supports various communication tools. ■ If you use LINE, Slack, Teams, Messenger, WhatsApp, etc., you can share necessary notes. ▼ Recommended for: ■ Those who want to reflect on their daily activities ■ Those looking to reassess how they use their time ■ Those seeking a simple note-taking app ■ Those wanting to start keeping a life log ▼ Main Features 【Timestamp】 Automatically inserts the current time with a single tap.
