Deliveries 9 from JuneCloud arrives Wednesday, September 30 for Apple devices. It will be a subscription-based app that costs US$0.99/month or US$4.99/year.
If you previously purchased the app, you’ll get a complimentary subscription for up to 18 months from the date you purchased it. If you bought the app more than 18 months ago, your complimentary subscription will end February 1, 2021. You’ll continue to have access to most features of the app even after your complimentary subscription ends.
On their support page it looks like the app will be useless without a subscription. If you want to add new deliveries and sync with iCloud then you’ll have to pay up.
