What's New in RuinRisk

4.4

September 30, 2026

This update requires iOS 18 or later. • Inputs are remembered. Win rate, risk:reward and capital risk are kept for the next launch. "Reset Inputs to Defaults" in the menu (Legacy) or in Settings (Pro) restores the starting values. • Type values directly in Legacy mode. Tap the pencil icon to enter a number instead of using the slider. Also fixed an issue in Pro mode where a value typed with a comma as the decimal separator was discarded. • Kelly guidance revised (Pro). The app no longer suggests raising your risk toward the Kelly figure. It flags position sizes above the Kelly reference and always shows the assumptions and limits behind that figure. • Clearer HEATMAP (Pro). The three inputs are now compared on the same scale, labels have been reworded, and a note appears when your current setting is outside the chart's range. • Plan comparison (Pro). You can apply a saved plan to your inputs. When the five-plan limit is reached, the app now tells you instead of removing the oldest plan. • Accessibility. VoiceOver labels for buttons, sliders and the heatmap, layouts that adapt to larger text sizes, and support for Reduce Motion. • Faster analysis (Pro). Monte Carlo results are cached, so returning to the same settings is quicker, and a calculation stops when you leave the screen. • iPad. Fixed the Legacy heatmap appearing small and off to the left. • Purchase screen. If product information can't be loaded, you can try again, and Restore purchase is always available. • Other small fixes, including a message when a CSV file can't be created.

Almost perfect

Really good app, the developer gets it while others don’t, the only thing it needs is the ability to change the “ruin” threshold, to say 20% for instance, to calculate the risk of drawdown to the custom level. Will change to 5 stars if added

Response from developer

Thank you for your review and comments. I will take your ideas into consideration for future updates.

手放せません

自分のトレードの安全性を確認するのに最適です。破産確率のマトリックスをすぐに表示できるのも素晴らしいです。多くのトレーダーに使って頂きたいアプリです。

Response from developer

評価とコメントありがとうございます。皆さんのお役に立てていれば嬉しいです。

目標設定がわかりませんね。

ゴールが10倍なのか100倍なのか。
その設定で数値も変わってくる。
それがないなんて信用できない。

Response from developer

目標は各々で設定してもらえれば良いと思います。それ次第でリスクをどこまで取るかが決まり、設定値も変わってきます。またこのアプリはあくまでも将来をシミュレーションした確率を求めるものです。その点をご理解ください。

リスク資金比率の改善ありがとうございました!

リスク資金比率を細かく見れるように、要望したところ、早速改善いただきありがとうございます。
