Summa – AI Calculator & Notes

You ask something, Summa AI writes the calculation for it. Whether the electric car pays off, how much paint three rooms need, what the travel budget leaves per day – line by line, with every assumption. Change a value, and the result follows at once. Ask what decides the result, or have a single line changed. You can also calculate yourself, as on paper: every line shows its result. Plus tables, sliders, percentages, units, currencies, deadlines and loans. Your notes live in your iCloud and are the same on iPhone, iPad and Mac. No account, no ads, and Summa collects no data about you. Requests to Summa AI are processed by Apple, not by the developer. FREE, PRO AND AI • Free: up to three notes at a time, every calculation feature • Summa Pro: unlimited notes, charts, PDF export – one purchase • Summa AI: subscription with unlimited notes.
