Cons
- App appears to be mainly a wrapper around the website — may feel less native and have fewer offline or advanced mobile features.
- Coverage, while large (~50k), still may miss many products or local/brand-specific items; completeness depends on their data sources.
- Last notable update notes in the store go up to 2018 (and some earlier changelogs), which could indicate slow maintenance or potential staleness of data/features.
- Very few user ratings in the App Store (1 rating), so real-world user experience and community feedback are limited.
- Some features were removed over time (e.g., Facebook login, certain campaign features), which may indicate shifting priorities or reduced functionality compared to earlier versions.
- Small independent foundation may mean limited resources for rapid feature development, data updates, or broad platform support.
- Removed landscape mode and some UI changes in the past — layout/UX choices may not suit all users or device orientations.
- Privacy/preferences: historical use of Facebook login (now removed) suggests authentication and account migration issues for some users; users concerned about privacy should review current policies on the site.
