Your life in memories. A first word. A family trip. An ordinary afternoon you want to remember. DiaryVault brings your photos, videos, voice notes and words together, so you can keep the story around each moment. CREATE MEMORIES FROM YOUR PHOTOS Select photos and choose Create memories. With your permission, AI creates and saves Memory Cards with suggested titles, descriptions and keywords. Edit them anytime to make the story your own. Choose Save originals only to keep your media without creating AI Memory Cards. CAPTURE THE DETAILS Browse your photos and videos in Quick Capture, take a photo, record a voice note or write a few words while the moment is fresh. Add a saved note to your current draft when you want more context; the original note stays unchanged. Manage imported photos and videos in Library, including removing completed items while keeping existing Memory Cards and device photos. EXPLORE YOUR CONSTELLATION Revisit your memories through time, people, themes and places. Search for a moment, open its Memory Card and explore the memories within a Star. Add people by their DiaryVault username or profile link, or keep a private person without an account. You choose which memories to associate and share. REMEMBER TOGETHER Share a full Memory Card with a link. Add an optional voice question or written message, and let someone reply with text or voice in their browser without downloading the app or signing in. Full-memory links include later edits and added media. Replies are private to you by default. If you enable shared replies, recipients can choose to make their reply visible to others with the link. Guest names are self-reported. An optional passcode can protect the link. SHARE A STAR WITH ONE LINK Share selected Memory Cards or a Star of connected memories with a website link. Add an optional passcode to a Star link. Recipients can view the shared Star, and users who sign in can save one independent private copy to their own constellation. If they already have a copy, they can open it again. Keep memories personal or invite people into a shared Star through Together. Saving a memory does not publish it. Adding a person does not grant access to your vault. Anyone with a working share link and, when required, its passcode can view the content shared through it. Public Discover rankings display your account username and points; your memories stay private unless you choose to share them. MAKE IT YOURS Update titles, descriptions and keywords whenever you like. AI memory creation uses Google Gemini with your permission. You can manage AI permission in Settings. DiaryVault is available in English, Korean, Japanese, Simplified Chinese, Spanish, French, German, Italian and Brazilian Portuguese. Optional monthly and yearly storage subscriptions are available. Eligible plans, local prices and plan details are shown before purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel your subscription in your Apple account settings. Privacy Policy: https://diaryvault.com/privacy/ Terms of Service: https://diaryvault.com/terms/
Schlummer
Read full descriptionHide full description
Schlummer is a sleep tracker app for iPhone that combines sleep-stage analysis, a gentle smart alarm, and on-device snore and sleep-talk recording in one app, plus 12 built-in sleep soundscapes. The smart alarm wakes you during light sleep inside your chosen window, and every night gets a readable sleep curve and a sleep score. Sleep analysis runs on your iPhone without an account, and your sleep data stays on your device. A banner and an occasional full-screen ad keep the free version going, and Schlummer Pro removes them. WAKE UP GENTLY, OR NOT AT ALL The smart alarm wakes you during light sleep inside your personal window so you start the day more rested. Snooze works even in gentle-wake mode. Pick your own alarm sound: three built-in tones, any song from your music library, or an audio file. It fades in gently rather than jolting you awake. And if you only want to see how you slept, switch the alarm off entirely and Schlummer simply measures your night. UNDERSTAND YOUR NIGHT A beautiful, readable sleep curve and a sleep score show how your night went at a glance. We treat the numbers as a wellness trend, not a medical measurement. HEAR WHAT YOU DO AT NIGHT Snoring and sleep-talk are recorded on-device only at loud moments. Play them back in the morning, tag a partner, and share as a video with a waveform. Rather not record anything? Switch it off: your sleep stages keep working and nothing is written to your iPhone. FALL ASLEEP CALMLY 12 on-device generated soundscapes (rain, ocean, wind and more) with a sleep timer. SEE EVERY NIGHT The Morning tab keeps your nights in one list with a score trend. The free version holds the last seven nights; Schlummer Pro keeps the whole archive and the long-term trend. HONEST, NOT GREEDY The smart alarm, your own alarm sound, snore recording, your sleep score and sharing a night as a video are free. Schlummer Pro adds your full night archive, the long-term trend, all 12 soundscapes and removes the ads: monthly, yearly, or a one-time Lifetime with no subscription. We never raise the price on features you already own. PRIVATE BY DESIGN No account is needed for sleep tracking. Your sleep data stays on your iPhone. Ads are delivered by Google AdMob and you are asked for consent first; Schlummer Pro removes them. Note: Schlummer is a wellness product, not a medical device. For a reliable alarm we recommend charging your iPhone overnight and keeping the ringer on. SUBSCRIPTION DETAILS Schlummer Pro is available as an auto-renewable subscription: Monthly (4.99 EUR per month) or Yearly (29.99 EUR per year, approx. 2.50 EUR per month, includes a 3-day free trial). A one-time Lifetime purchase (69.99 EUR) is also available and is not a subscription. Payment is charged to your Apple Account at confirmation of purchase. A subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or cancel your subscription in your Apple Account settings after purchase. Any unused portion of a free trial is forfeited when you purchase a subscription.

Verdict
The clearest difference is ads: DiaryVault at none against Schlummer's shown. DiaryVault also leads on update cadence (every 3 days vs every 3 weeks) and device support (3 vs 1). On price and in-app purchases there is nothing between them.
