1Lens is a metacognition practice and reflection tool. Choose a mental model you want to work on, record your decisions and actions in everyday situations, and look back on what changed. β’ Practice mental models: Start with built-in models such as First Principles, Win-Win Thinking, and Growth Mindset, or create your own. Keep up to three models active to stay focused. β’ Record wins and misses: Note what went well or where you fell short. Make a specific βIfβ¦thenβ¦β plan for your next attempt. β’ Reflect with voice: Record your thoughts and, when supported by the device, transcribe them with Appleβs system speech recognition. Recordings, transcripts, and practice entries stay on your device. β’ Review your progress: Browse recent daily entries and reflection history, and use your practice streak to notice your rhythm. β’ Make it yours: Edit or archive models, then reactivate them from the full list whenever you are ready. Optional reminders can help you build a routine. Take a moment to notice how you think, then choose what to do next. Microphone access is used to record voice reflections. Speech recognition access is used for on-device transcription. Recording starts only when you choose to begin.
Kurir Email
Read full descriptionHide full description
Kurir is a mail app for iPhone and Mac where new senders knock first. It works with the mail account you already have: iCloud, Gmail, Fastmail or any IMAP server. There is no Kurir account and no server to run. THE SCREENER The first time someone writes to you, their mail waits in the Screener. One tap sends the sender to the Imbox, The Feed or Paper Trail. Another blocks them. You decide once per sender, or once for a whole domain, and Kurir remembers. THREE PLACES, NOT ONE PILE The Imbox holds mail from people you approved. The Feed holds the newsletters you chose to keep. Paper Trail holds receipts, bookings and shipping notices, found with search the day you need one. YOUR MAILBOX IS THE SYNC Kurir keeps your screening choices, rules, snoozes and settings in a hidden folder in your own mailbox. Your iPhone and your Mac both read it, so they agree without a server in between. Turn on encryption and that folder is sealed with a passphrase only you know. CALENDAR Connect an iCloud, Google, Fastmail or other CalDAV calendar, or subscribe to an .ics link. Day, week and month views show how many hours are still open, and the next meeting sits on top with a Join button. NEW MAIL RIGHT AWAY Kurir Push keeps checking your mail and pushes new mail to your iPhone. It runs on a Mac with Kurir open, or on a server of your own. Without it, the iPhone checks for new mail when iOS lets it. AND THE REST Reply Later, snooze, follow-ups, send later, pinned threads, Collections, contacts and groups, a list of every attachment, several accounts, and search across all your mail on the device. Images that report when you open a mail stay blocked. AI ON YOUR OWN SUBSCRIPTION Draft generation and AI Rules run on the Claude subscription you connect in Settings. The mail a feature needs goes straight to Anthropic, with no Kurir server in between. PRIVATE No analytics and no tracking. Your mail stays on your device and your mail server. SUBSCRIPTION Kurir is free to download and needs a subscription, yearly or monthly. The yearly plan starts with a free month and the monthly plan with a free week. Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the period ends. Manage or cancel it in your Apple Account settings.

Verdict
The clearest difference is price: Kurir Email at Free against 1Lens's $0.99. 1Lens's advantage is in-app purchases (none vs 2) and update cadence (daily vs every 3 days). On ads, device support and iOS requirement there is nothing between them.
