Steal data before asking to pay

AlvaroZAV on

Spain

Apps should show the payment/fee trial before asking all the questions about you, they gather all data and then they ask you to pay, that doesn’t look ethically correct.

Not really free

uberana on

Spain

Looks good but I managed to delete it after 5 minutes due to the consistent reminder to subscribe and pay to use the app that blocks you from using it. Very annoying and I won’t be paying for anything unless I can actually see if I like it first (without subscribing to the free trial). It’s a no from me.

The app only available in english

A simple app that does what it’s needed to without annoying notifications, ads or pushing to subscribe!

This is it

ThierryJ on

Spain

We came a long way, but I cannot bare that anymore, from a simple app with full respect of privacy l, to this …. Really a pain when you have to leave because Terms of use are way out of line. There should not be any need to collect that much information that are clearly irrelevant for the purpose of this app.

No está actualizada para watchOS 10

Eatlon on

Spain

No tiene widgets para watchOS 10. :( Y la nueva interfaz de empezar / acabar un ayuno es muy confusa.

There is no free-version

Lokifacio on

Spain

The app forces you to choose at least a 7 days trial version.

Great

T.textura on

Spain

Great app even on free mode. A lot of apps free mode are bare bones and don’t really work. This app is simple but very practical
