Solar Planner

App to calculate the solar production. The app calculates the reduced solar earnings compared to an optimal panel position. Two factors reduce the real solar earnings: 1. The direction and the tilt angle of the solar panel. 2. The shadowing due to buildings or trees. The yellow area in the pictureΒ shows the possible positions of the sun during the year. The brown area represents the ground to the horizon. Using augmented reality the shadowing is drawn directly on the screen by repainting the buildings or trees. The direction and the tilt angle of the solar panel are set by using the direction and tilt angle of the iPhone/iPad. Either by holding the iPhone/iPad in the direction of the sun. Or by laying the iPhone/iPad on the solar panel. (The tilt angle can be 90Β° at maximum.) The result of the calculation shows the solar earnings compared to the highest possible solar earning in percent. The solar earnings are also shown in a year diagram and a day diagram. The Calculations can be used for photovoltaic and solar heating systems. Used methodology: For every time during the year the position of the sun at the sky depending on the geographic location is calculated.Β The solarisation on the panel is calculated by taking into account the panel direction and the panel tilt angle. The solarization is summed up for all times without shadowing. The calculated solar earning of the calculated panel position is shown compared to the maximal possible solar earning in percent.

The Square Is

The Square Is - a daily ritual of digital resistance. We have lost the ability to be absent. The digital world is noise. The Square Is: the return to the zero of form. One hour of total black. No content. No scrolling. Leave the screen, and the session ends. THE DISCIPLINE Each day, the Square waits. You come when you are ready - morning, noon, or night. Three attempts. Every start consumes one, whether it ends in the journal or in a crack. The day does not grant a fourth. Once you begin, you do not leave. THE BLACKOUT Initiate the manifest. The screen becomes a solid black square. No content. No exits. No distractions. Just you and 60 minutes of total presence. THE REFLECTION After one hour, a solitary cursor appears. Record your thoughts. Or let them disappear. This is your choice. THE RECAP On the final day of each month, the Square reveals the sum of your resistance. An echo of your mind while the world was yours. WE REJECT THE ALGORITHM We reject the infinite scroll. We reject the constant "on". We value absence over engagement. We offer silence over content. A daily reminder is optional - a fixed hour, or a random one. Not a command. An invitation. You come on your own, or not at all. TOTAL CONFIDENTIALITY On iOS we store absolutely no data about you. No account. No name. No cloud. Your journal never leaves this device. THE INITIATION 7-Day Trial: experience the void. Keep it, or leave. Lifetime License: $9.99. In an era of endless subscriptions, reclaim the ritual once. This is not a tool. It is an act of liberation. Some of us choose the Square.

Verdict
The clearest difference is ads: The Square Is at none against Solar Planner's shown. Solar Planner's advantage is update cadence (daily vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
