Meet your mysterious new companion — a 3D character that lives inside your caffeine tracker and reacts to your body's caffeine level in real time. Sleepy when you're clean, dancing when you're at peak, jittery when you've had too much. The numbers on a graph, finally with a face. MyDailyCaffeine is the smart way to track and manage your daily caffeine intake. Coffee, espresso, tea, matcha, energy drinks — log them all in seconds and see exactly how your body feels, minute by minute. ◆ Meet Your Mystery Mascot (NEW) A 3D animated character appears on your Today tab. Their pose and mood are driven by your actual caffeine curve, so a single glance tells you more than any chart. Tap them for a surprise reaction. Drag to rotate. Pinch to zoom. You can toggle them off anytime from Settings. ◆ Track Caffeine Intake Record every caffeinated drink with one tap. Coffee (95mg), espresso (63mg), green tea (28mg), matcha (70mg), energy drinks (80mg), cola, cocoa, chocolate — and create custom drinks with your own values. ◆ Daily Caffeine Limit Set a personal daily cap (default 400mg, the WHO healthy-adult guideline). See at a glance how much you've consumed versus your target. ◆ Remaining Caffeine in Your Body Know exactly how much caffeine is still active in your system using a 5-hour half-life model. Decide whether that afternoon cup is a good idea — before you pour it. ◆ Calendar Heatmap Spot weekly patterns and habit shifts with a color-coded monthly calendar. ◆ Statistics and Trends 7, 30, and 90-day analytics. Daily averages, most-consumed drinks, long-term trends. ◆ Streaks and Badges A gentle streak system and achievement badges keep the daily logging habit going. ◆ Widget Support Home Screen widgets for an instant caffeine summary, no app open required. ◆ Apple Watch App Log your coffee right from your wrist and check your current caffeine level at a glance. ◆ Personalization Eight theme colors inspired by coffee (espresso, mocha, caramel, matcha, chai, berry, midnight, slate).

Orloは、その日撮った写真をカレンダーにまとめていく日記アプリです。「今日何があったか」を写真とちょっとしたメモで残せます。 毎日開きたくなるような、心地よい操作感にこだわって作りました。 ■ アプリを開いてすぐ撮影 カメラがアプリに入っているため、別のカメラアプリを開く必要がありません。 フィルター機能もついているので、撮った写真をそのまま日記にできます。 ■ 触っていて気持ちいいアニメーション 毎日使うアプリだからこそ、操作の心地よさにこだわっています。 カレンダーや一覧の写真をタップすると、途切れることなく滑らかに拡大します。 写真を見終わったら、画面を下へスワイプ(指で払う操作)するだけでスッと元の画面に戻れます。 カレンダーの月切り替えも、指の動きに合わせてスムーズに動きます。 ■ カレンダーで振り返る 保存した日記はカレンダーやタイムライン形式で整理されます。先月や去年の今日、何をしていたかをさっと見返せます。 ■ 見た目を自分好みに アプリの背景色(テーマ)や文字のフォントを自由に変更できます。自分の読みやすい、好きなデザインで使えます。

Verdict
The clearest difference is in-app purchases: Orlo at none against Caffeine Tracker's 1. Orlo also leads on ads (none vs shown). Caffeine Tracker's advantage is update cadence (every 9 days vs every 2 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
