Good but can’t share the app

Seemed to work fine on my phone , I paid for a yearly subscription and that’s where they get you - i shares the app with the rest of the phones on my family but I can’t use the app on wife and siblings phones without paying £9.99 each on those as well - it says “ in app purchases can’t be shared “ I paid for it through iTunes , not paying £40 a year for 4 family phones !!! Deleted app and cancelled subscription , shame really as it looked the part

Developer Response ,

Family sharing is enabled for our app. Please contact Apple support why it doesn't work for you as it's their native service and they are responsible for that.

Quirky app

Installed the app and tried the trial. Couldn’t even update the database. It consistently failed at 60% every time I tried. I tried entering a number manually which is a known scam and it wasn’t detected. If I can get it working I’ll update my review but this isn’t a promising start.
EDIT: Gave it all another try several hours later and the database updater still fails. Waste of time. Uninstalled and subscription cancelled.

Developer Response ,

We have replicated the problem. It's related to extension status.
Make sure all the extensions are fully enabled in the iPhone setting otherwise the app is not correctly set in the iPhone and can not save it’s numbers to the iPhone internal database.

The major Numbo update was just issued.
New database, 8M numbers in internal iPhone database - biggest in the market as competitors have up to 2.3M numbers.
The whitelist of services and institutions is included too.

Feel free to try the update.
You can contact our help line at and we will try to solve your problem.
