- 💰 Revenue: Modest — $4K - $8K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.4★ across 2,167 reviews — strong (top 10%).
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: dev shipping weekly.
- ⚠️ Risk: Low — no material risk signals detected.
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $104K-$185K. Portfolio play ($17K/mo combined) commands premium.

📝 About this app
GW Mailbox is a GroupWise email and calendar app for the iPhone and iPad. With this app you get a much better interface than Novell delivers by default through GroupWise WebAccess. This app gives you some of the enterprise features that you wouldn't get with simple POP/IMAP - like access to your Frequent Contacts and GroupWise address book.
This app is designed to work with a Novell GroupWise email server. Novell GroupWise is an email server like Lotus Notes or Microsoft Exchange. If you do not have access to a Novell GroupWise email account, this app will not work for you.… View full description on the official store →
