I just finished my current grocery app delivery project.
Except obvious and boring features like responsive templates and Google map integrations I've done 4 interesting features:
- AI for product recommendations
- Rich push notifications. That increase CTR on 30%
- Admin KPI funnels
- Synchronisation with accounting systems (auto import / auto push)
More detailed list of features is in my article: Top-16 features of grocery app
P.s.: Which other interesting features I can suggest to my client?
