Developer Cut Features From Paid App

I purchased Tabi Calc for date calculations before the developer switched to a subscription model. Those features (that I already paid for) are now locked behind a subscription. Restoring the purchase does nothing. Fortunately, every feature this app offers is available in the iOS calculator or from Google for free.

Não funciona sem assinatura

Era um bom app, mas agora precisa de assinatura para fazer qualquer coisa que não sejam contas de calculadora básica, ou seja, use o app original do iPhone que é grátis.

Se quiser qualquer outra função, agora é preciso pagar a assinatura.

Não recomendo.

Unscrupulous developer

Dev changed to subscription model without grandfathering in previous paid customers. How is this even legal?

Une honte

J’ai acheté cette application il y a un plus de 5 ans je l’utilisais de temps en temps, très pratique.
Maintenant il faut un abonnement.
honte à vous.

Added subscription! Pass

Not worth $8. Would have paid $2 for the full app but certainly not that much.
