RoninDesk Analytics

Ronin Prime focuses on interpreting markets. Zezpro focuses on the path from an alert to a configured destination. Our free utilities help people calculate, inspect and prepare. Each product has its own website, access model and product policies.

Eight focused utilities. No sign-up or paid plan is required. Read the method and worked example, then use the interactive calculator or converter.

RoninDesk is founder-led and has been building since 2024. That is the business founding year, rather than a claim about formal incorporation. Our focus is useful software, explicit product boundaries and clear documentation.
