PRIVATE BY DESIGN Your journal and codex are kept on your device, and Mementia keeps its own copy of the photos you add, so you can delete them from your camera roll and still keep them here. Mementia runs no content servers and cannot see your entries. Backup and sync are encrypted on your device before upload to your own iCloud or Google Drive, so Mementia cannot read them. Subscriptions are validated by RevenueCat using an anonymous app user id. Anonymous feedback and early-testing requests are optional and send only what you type. Details are in the privacy policy. A quiet place to keep your one life, and to find it again later. Mementia+ is an auto-renewing subscription, offered monthly, every 6 months, or yearly, with a 30-day free trial for eligible new subscribers. In the United States it is $0.99 per month, $4.99 every 6 months, or $9.99 per year; the app shows the price for your region before you subscribe. Payment is charged to your App Store account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel in your App Store account settings. Privacy policy: https://mementia.cyberflux.in/privacy Terms of use: https://mementia.cyberflux.in/terms

Verdict
The clearest difference is in-app purchases: Idea Store at none against Mementia's 3. Mementia's advantage is update cadence (every 2 days vs every 2 months) and iOS requirement (13.0 vs 15.6). On price, ads and device support there is nothing between them.
