## Review summary

CalcNote is praised for strong calculator functionality and general usefulness, with some reviews highlighting currency exchange as a notable feature. However, widespread complaints focus on intrusive ads and long wait times, a costly subscription model (and desire for a one-time purchase), and post-update stability/UI issues that degrade usability. Purchase restoration problems add to user frustration. Overall, core features are solid, but monetization strategy and reliability concerns dominate the feedback.

### Pros

- Best-in-class calculator functionality praised by multiple reviewers
- Overall positive user experience with the app and broad appreciation for its usefulness
- Currency exchange support noted as a useful feature

### Cons

- Intrusive ads and frequent interruptions (including 5-second countdowns) that disrupt usage
- Aggressive monetization via subscriptions with high prices, and perceived shift away from a one-time purchase
- Post-update stability issues such as freezes/crashes, font size glitches, and misaligned results
- Problems restoring purchases (e.g., lifetime Pro subscription not being recognized)
