Just Make This a Paid App
If you want to be a paid app, be a paid app. If you want in-app purchases for advanced options, go right ahead. However, it’s pretty cheap of a developer to have someone pay just to add in their reptile. That kind of information should be communicated to customers BEFORE they waste their time downloading the app.
I’ll stick to a physical journal instead of this crock.
Add more reptiles
Response from developer
Hi herpnerd513, Thanks for downloading the app. You can add any reptile species in Settings > Configuration > Species. You can also customize the feeders and adapt them to the reptiles you have in your collection. It's the same process: Settings > Configuration > Feeders. Please don't hesitate if you have any other question.
