The same behavior happened when sync came out. Endless complaints about an app being from on app store with the option to pay the hard working developer for their work.
Do they go on public transit complaining that see ads there too? At least when you pay for the app the ads go away forever.
This is cool. I use an app a lot like this but for my puppy. Logging is super helpful at the start of getting a puppy and trying to track bowel habits and training progress.
If you ever feel like it, a mode for tracking puppies is useful. I currently use “Doggy Time” by a developer that also makes a similar baby tracker.
