Hi, I have just re-installed Cydia on my iPhone 4 running 7.1.2 for the first time in about a year and it's saying "Unable to Load (The certificate for this server is invalid.

Https://cydia.saurik.com/ is the only official cydia website. Source: over 2 years ago

The site you linked to (hxxps://cydia-app.com/) is unofficial, links to piracy and spyware sites, and should not be trusted. The official Cydia site is http://cydia.saurik.com/ but it doesn't include much information about Cydia and jailbreaks.

I used Grocy for this, mostly because I had bigger plans for this (e.g. Meal planning and inventory of our kitchen cupboard), but I also found success with Loop Habit Tracker (free, Android, open source so you can inspect the code and build it yourself if you wanted). Source: about 1 year ago
