Free to start. Fair when you upgrade.
No ads at any tier — ever. CueCalc Pro unlocks Cues Studio, the AR Math Solver, and every premium theme.
We think ads in a calculator are disrespectful. Free users pay nothing and see nothing. Every new install also gets a 7-day trial of everything in Pro, automatically, with no card required — pick a plan below only once you're ready to keep it.
All three plans unlock the exact same set of Pro features below — Monthly, Yearly, and Lifetime only differ in price and billing period.
- Every Pro feature (see below)
- Lowest commitment
- Cancel anytime in Settings
- Every Pro feature (see below)
- 37% cheaper than paying monthly
- One payment, one reminder a year
- Every Pro feature (see below)
- No recurring fees, ever
- Every future Pro feature included
Prices shown in USD and may vary by region. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in iOS Settings > [your name] > Subscriptions. See our Terms of Use for full billing terms.
