\(当時)妊娠8ヶ月の開発者が、自分のために作りました!/ 体重管理アプリをたくさん試したけれど、 どれも機能が多すぎて、使いこなせない。 私が知りたいのは、ただひとつ。 「今の体重増加、大丈夫かな?」 このアプリは、その答えだけをシンプルに教えてくれます! 産婦人科診療ガイドラインで示されている値をベースに、 あなたのBMIに合わせた適正範囲を表示。 体重を記録すると、グラフで一目瞭然。 余計な機能は、一切ありません。 広告も、課金も、ありません。 妊娠中って、頭がぼーっとしますよね... せめて体重管理くらいは、シンプルに! そんな想いで作りました。 同じように「シンプルがいい」と思うあなたへ。 ぜひ使ってみてください! ※ガイドラインはあくまで目安です。必ず医師の指導に従ってください。

CafLog helps you log caffeine in seconds and see how much will still be in your body at bedtime. - Your drinks become a 3D scene Each time you log a drink, a cup, can or bottle drops from the top of the screen and piles up at the bottom. The pile resets every week, so you can see at a glance how much you've had this week. You can grab and move the drinks with your finger. - Quick logging Pick from 26 drinks, including coffee, espresso, green tea and energy drinks. Long-press the log button to bring up your favorites. Adjust the amount or time later, and add your own drinks. - Coffee-kun tells you about your sleep CafLog estimates the caffeine in your body now and what will be left at your bedtime. Coffee-kun, the app's character, sums up your day in one line. - Look back with a monthly grid Each day of the month is a square shaded by how much you had. Days without a record show as no-caffeine days. Highlights are summed up in four cards. - Rewards that grow as you go Keep logging to climb six achievement levels. Each level unlocks rewards: Coffee-kun expression icons, Coffee-kun artwork, themes for the whole app and 3D looks. - Widgets Check today's total and your bedtime estimate on the Home Screen and Lock Screen. - CafLog Pro (auto-renewing subscription) - Past records (earlier weeks in 3D and earlier months in Review) - Metabolism simulation (your caffeine curve) - Every look unlocked - Saving to Apple Health and iCloud sync - Up to 4 favorites - No ads Monthly and yearly plans are available.

Verdict
The clearest difference is ads: 妊婦の体重管理 at none against CafLog's shown. 妊婦の体重管理 also leads on update cadence (every 2 months vs every 7 months) and iOS requirement (13.0 vs 26.1). On price, in-app purchases and device support there is nothing between them.
