## Review summary

Reviews consistently praise calculation accuracy and an ad-free experience, but complain about pricing/friction with IAPs and missing TI-84 features. Multiple users report stability issues with table functions and input handling, and several criticize unclear lifetime upgrades and ongoing subscription costs. Overall sentiment is mixed: strong math performance but significant pain points around pricing and feature parity.

### Pros

- Accurate calculations and reliable results (including correct exponent handling)
- Ad-free interface with no pop-up ads
- Helpful for statistics tasks (as noted by reviewers)

### Cons

- Pricing model shifts toward a subscription with ongoing costs and unclear lifetime upgrade terms
- Missing TI-84 features (e.g., numeric solver and ability to create programs) compared to TI-84 Plus CE
- Bugs and instability in table and input handling (table crashes, domain errors, negative matrix input restrictions)
