I made a free Android app called Counter that can call a Home Assistant webhook when a counter reaches a value. It turns a simple tally (taps, NFC, widget, volume keys) into a trigger for your HA automations, without writing code.
How it works:
-
In HA, create an automation with a Webhook trigger and note the webhook URL.
-
In Counter, open a counter, go to Events and Actions, add a rule with a Webhook action.
-
Set the URL to your HA webhook, method POST, and a JSON body with template variables, for example {"counter": "{{title}}", "value": {{value}}}.

It also sends Tasker/Automate broadcast intents and Telegram messages, and can write NFC tags. Disclosure: I am the developer, and I would love feedback on what to support next for HA users.
