### 1/5 — Worst App

*2024-10-08*

Make it user friendly… This app logic is stupid…

### 2/5 — Relational Objects and Normalization

*2024-07-30*

The idea is very good. However, users are unable to assign relational tables and relation types (1 to many, many to many etc.). Also there is no editable file sharing option. Hıpe to see this app better in the future.

### 1/5 — Publicidad molesta y no permite crear tablas ni campos con guion bajo

*2023-03-05*

Me parece una aplicación muy mala, de entrada ya me molesto la publicidad que no la puedes eliminar de inmediato, al crear la primera tabla ya no podia cargar el nombre TA_TABLA, cuando intento crear un campo de la tabla tampoco puedo ingresar ID_CAMPO

**Developer response:** Hola

Gracias por sus comentarios honestos.  Sus comentarios fueron útiles, así que facilité agregar nuevas columnas (arrastrar y soltar).  La nueva versión está actualmente en revisión y estará disponible muy pronto.

Sobre el anuncio.  Hay una versión profesional sin anuncios y con más funciones.  Los desarrolladores necesitan generar algunos ingresos para mantener estas aplicaciones disponibles.

Gracias por usar la aplicación.

Agradecemos cualquier comentario.

Gracias.

### 3/5 — UI Needs Finessing

*2022-07-16*

Seems to be in a market of one, can't find another ER diagrammer on the App Store.

Few things need to be addressed.

Reorientation from landscape to portrait causes buttons to not be visible.

Cannot seem to delete (perhaps it's a pro feature, can't tell the difference between paid and free version)

Attribute type is a button to cycle through, painful when it should be a drop down.

Has potential with some polish and fixes.

**Developer response:** Hi. 

Thank you for the feedback. I listened to your review and tried to improve app design. You can now see the title to the buttons on what they do. Help screen is improved with instructions. Added dropdown button for elements where choice among multiple items exist like datatype. No need to cycle through button anymore. 

Could you check out the new version and rate the app again?

Merry christmas and happy new year.

### 2/5 — More instructions needed

*2022-06-08*

I like this app, it creates the SQL for tables you create. You’re able to add relationships and plan your database. 

It could be good. 

The issue is the lack of clarity with instructions. The help tab offers limited help. To be user friendly it needs:

Icons - with explanations of what each one does. 

A step by step tutorial with screenshots showing which icon to select. 

I set up my first tables, eventually worked out how to create relationships then pressed what I thought was a note icon. Nothing happened so I pressed it again, longer - it cleared everything from my page and I was back to a new blank page with no way, that I could find, to undo this. 

I’d lost everything I’d created, in search of a note icon.
