## Review summary

Button Mapper is valued for its core ability to remap hardware keys and add practical actions, and is noted for being simple to use. However, recurring drawbacks include a restrictive Pro/paywall with unlock issues, reliability problems (remappings failing or resetting, especially on TVs), and Android TV limitations. Additional frustration comes from unlabeled custom buttons and unclear backup/restore paths. Overall, it’s functional but hampered by paywall friction and stability concerns.

### Pros

- Effectively remaps hardware keys (e.g., volume, power) and supports various button mappings.
- Simple to use for basic tasks and works as described.
- Adds practical features like a dedicated flashlight button on some devices.
- Valued for customization and essential for users who want customizable button behavior.

### Cons

- Pro unlocks and paywall are frequently problematic; users report issues purchasing or accessing Pro features.
- Remappings can be unreliable or reset (e.g., back button mapping only works on first press; settings reset when the TV turns off).
- Android TV users report limitations and paywall restrictions affecting functionality.
- UX/UI clarity issues (customized buttons lack labels; backup/restore paths on Google TV are unclear).
