Kyokun
Read full descriptionHide full description
When a mistake at work or in everyday life stays on your mind, use Kyokun to record what happened and the lesson you want to remember. Write one part at a time: roughly when it happened, what happened, how you felt, and what you learned. You can add a possible cause and a next action, plus a photo or voice note for context. If it happens again, add another occurrence to the same lesson. Review the count and the individual entries instead of losing them across separate diary pages. On the Mountain Range Home screen, each lesson's mountain grows with its repeat count. Pin lessons you want to revisit. Search and filter your records, or place a lesson on your Home Screen with a widget. Recording and reviewing lessons are available free with ads. An optional one-time purchase removes ads. This is a place to reflect on your own experiences; it does not promise to prevent mistakes.

Verdict
The clearest difference is in-app purchases: LinkFlow at none against Kyokun's 1. LinkFlow also leads on ads (none vs shown) and iOS requirement (13.0 vs 26.2). Kyokun's advantage is update cadence (every 4 weeks vs every 4 months). On price and device support there is nothing between them.
