【お手持ちの印鑑を電子印に!】実物の印鑑をもとに本格的な電子印鑑を作成するアプリです。 STEP1【印影を用意】 無地の白い紙に丁寧に押印する(すでに書類上に押印されている印鑑があればそれでも可)。これが画像になります。綺麗に押印されているものを用意すると仕上がりも綺麗になります。 STEP2【撮影】 アプリを起動し、明るい部屋で印影を撮影。 STEP3【調整】 枠に合わせて画像を拡大して完成(カラーの選択も可能)。背景の透過したPNG画像が出来上がります。 STEP4【共有】 ボタンひとつでメール添付、AirDrop、SNS共有、そして写真ライブラリへ保存できます。ExcelやWordにドラッグ&ドロップで貼り付けることができます。アプリ上では画質が低く見えますが、拡大表示しているためです。書類上では本物のように自然に見えます。書類に貼り付け後、最終的なサイズ調整を行なってください。 STEP5【ARで仕上がりを確認(おまけ)】 おまけ機能になりますが、AR技術を使って電子印鑑の仕上がりを確認することができます。机や紙などに端末をかざすことで、現実空間に押された3Dの電子印鑑を見ることができます。 【Pro版にアップグレード】 Pro版では、以下の機能がご利用できます。より繊細で美しい仕上がりを追求したい方に最適です。 ①「押印の力強さ」をスライダーで細かく調整できるようになります。 ② 印鑑画像を書き出す際に「高画質」「最高画質」を選択できるようになります。 ③ すべてのバナー・動画広告が非表示になります。 Photo印鑑は定期的にアップデートを行なっています。アプリへのご意見、ご要望がございましたらAppStoreのレビューからお知らせください。
Rubato

Rubato is a daily planner that stacks your events vertically and lets you clear them from the top. Instead of pinning everything to a time, you stack them in order. • A plan that flows Stack what you want to do and it lines up from the top. Run late and everything after shifts; finish early and it moves up. You always see the whole day. Meetings and appointments become "fixed-time" events, and flowing events split around them. • Stack and clear Tap a frequent event in the History palette to stack it, or drag it into place. Complete it and it bursts away; the next one becomes current. Completion sounds and haptics are designed in-house. • Usual Rubato predicts what usually comes next, based on the time of day, the weekday, and what came before, and puts it first in the palette. It gets smarter as you use it. • Your day ends when you sleep Past midnight, the timeline keeps counting: 25:00, 26:00. Night owls' days stay in one piece. • Live mode The current time stays near the top, with only the current event and the next one shown large. Insert a break or a gap with one tap. Notifications arrive when an event starts, 10 minutes before a fixed-time event, and at the planned end. • Works with your calendar Events from your iPhone calendars (including Google) appear in the header; tap one to place it at a fixed time. Mark an event "Show in Calendar" and it's written to the calendar you choose, follows the flow as it moves, and settles into the actual time when completed. Subscribe to calendars by URL (iCal). • All-day events and to-dos Add all-day events and undated to-dos to any day. Tap a to-do to finish it; unfinished ones carry over to tomorrow. Place them on future days from the month view. • iPhone and Mac On Mac, Rubato lives in the menu bar and can be pinned as a standalone panel. It syncs through iCloud. There's no server: your data stays in your own iCloud. • Pricing Free to download. Try every feature free for 14 days (started by a ¥0 in-app purchase; it isn't a subscription and you'll never be charged automatically). To keep going, a single one-time purchase (¥2,200 in Japan; local price shown in the app) unlocks Rubato on both iPhone and Mac, forever. After the trial, viewing, completing, and syncing keep working.

Verdict
The clearest difference is ads: Rubato at none against Photo印鑑's shown. Rubato also leads on update cadence (daily vs every 2 weeks) and device support (3 vs 1). Photo印鑑's advantage is iOS requirement (18.0 vs 26.5). On price and in-app purchases there is nothing between them.
