This is a customer service memo app that reduces the "What did I talk about with this customer before?" problem. You can organize what you've discussed, what you want to talk about next, and topics to avoid for each customer, then search and check before customer service interactions. No account registration is required, and memos are saved on your device. The free plan allows you to display up to 15 items, while Pro unlocks unlimited display slots and enables memo sharing via QR code. Compatible with iPhone and iPad.

Pro is an auto-renewing subscription at 500 yen per month or 4,800 yen per year.
