## Review summary

The app is praised for its ease of use and strong construction-focused features, making it a go-to tool for many professionals. However, widespread frustration centers on the shift to a subscription model, loss of lifetime ownership, transfer difficulties to new devices, and perceived high ongoing costs (often with ads). Despite solid functionality, pricing and license-management issues overshadow the positives for many users.

### Pros

- Easy to use and quick, convenient for on-site construction work
- Comprehensive construction-focused features (rafter calculator, feet/inches, conversions, slopes)
- Feels like a true standalone calculator with a familiar interface
- Reliable performance and is a trusted tool for professionals over time

### Cons

- Subscription-based pricing replacing a one-time purchase, which many users dislike
- Loss of lifetime license and difficulty transferring licenses/purchases to new devices
- Perceived high ongoing cost compared to standalone calculators
- Ads appearing after paying or within the app, seen as a negative
- Inconsistent account/license records and support issues around license restoration or transfer
