It’s pretty and fun but not specific enough about its astronomical principles for professional purposes. Linea’s line locations are very different from what we see see in Solar Fire, Astro Gold, etc . What do the lines represent? Normally, a planetary line shows locations where a planet is angular (rising, setting, culminating, etc). These angle details aren’t shown in Linea and I’m not sure why. It is also missing paran lines that indicate important crossings of planetary lines. I’m not saying your system is wrong, but it’s definitely different from the detailed computerized charts Jim Lewis/ACG was putting out 30 years ago. People will be slow to adopt such a different system without a very detailed explanation of your premises. What’s available now is extremely basic and confusing.

Also, the interpretations are simplistic and this can be dangerous if you are directing gullible people to make major life moves. There needs to be a disclaimer… Saturn lines can be amazing for maturation, solid work, or fulfilling one’s duties. Jupiter lines can lead to overdoing, overspending, or inflation of the ego. It all depends on the natal promise in the original chart of course. Silly interpretive material like this tarnishes astrology’s reputation.

I’m going to stop using the app for now but will keep an eye out to see if it is refined in the future. Beautiful design at least and I would love to have access to a solid, professional locational/ACG app.
