Pricing
Free, and honest about why.
Kuralta is free while it is being built, and there is no billing code in it. Not a trial and not a tier – there is nothing to enter a card into.
The reason is not generosity. A maintenance history is worth more the more of it exists, so the useful thing right now is records, not revenue.
When there is something worth charging for it will be aimed at bike shops and at people querying a bike they are about to buy, not at the owner keeping their own records. If that changes, it will change in public and not quietly.
Kuralta is not released yet
It is in development and not on any app store. Leave an email and you will hear once, when there is a build worth installing.
