Read full descriptionHide full description
Would you like to write down only the things you won't mind forgetting? Doudemo Memo is a memo app that “locks away the memory itself” — small everyday moments and things that only caught your attention for a moment. When you save a memo, its contents can no longer be read as-is. Later, enter words you remember. When your memories overlap, you can open the memo again. For example, ・Something mildly funny at the supermarket ・A thought that suddenly came to you on the train ・A trivial remark someone made ・A small event you'll probably forget in a few days Not important, but worth keeping just a little. This is a memo for memories like that. 【Key Features】 ・Write a note and lock it with Memory Lock ・Unlock a memo with words you remember ・View a list of locked memos ・See a short animation when unlocking ・Store data on your device ・Restore your purchases ・Delete all data from within the app 【Pricing】 The free version lets you store up to 10 locked memos. A one-time in-app purchase removes the storage limit. There are no ads or subscriptions. No account is required. 【Important】 This app is not a security app for storing important information such as passwords, financial information, or personal data. Please record only things you would not mind forgetting.

Verdict
The clearest difference is ads: Recall Memo at none against nikki's shown. Recall Memo also leads on update cadence (every 2 weeks vs every 2 months). nikki's advantage is iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.
