This simple simulator shows how space and time behave at relativistic velocities. It was developed as a pedagogical tool as part of a master's dissertation at the Federal University of Espírito Santo. Thus, it does not take into account the acceleration effects of the spacecraft. It was developed in a partnership between Prof Thiéberson Gomes (UFES), Prof Flávio Gimenes (UFES) and student Luiz Henrique Gobbi, with computational support Rodrigo Marques.
Formula Conversion

It is a formula conversion application. You can print a formula or a modified formula. You can save unmodified formulas to your phone's storage medium and then open it if necessary. Upgrading An application without an upgrade is limited to 24 formula conversions. If you want to convert the formula more than ten times, you must make an in-app purchase. Creating and opening a formula You can open the formula by clicking the first button on the toolbar. You can create a new formula using the symbols, symbols, numbers, and letters on the keyboard. You can change the font size of letters and symbols by pressing the "alp." Or "ALP." And "sym." Or "SYM." Buttons on the toolbar. If you wish, you can delete the characters by pressing the "del." Key. And use the arrows to move between the elements of the formula. Formatting the formula You can format the formula by first selecting the characters you want to change. The selection key is "Sel.", And you can then select by scrolling between the elements of the formula or by pressing the finger on the desired character. You can format the selected formula by pressing the second button on the toolbar from the back. You can change the font, font size, font, and font color Saving and printing the sample You can save the formula by pressing another button on the toolbar. Press the third button on the toolbar to print. If you want to delete the saved formulas, press the fourth button on the toolbar. Converting a formula When the formula is ready, you can publish parts of the formula. To publish part of a formula, select the item with the cursor. Press the fifth button on the toolbar to publish the formula. You can also print the converted formula by clicking the "Print" button. Zoom a formula If you want to increase or decrease the formula, press the third button on the back of the toolbar.

Verdict
The clearest difference is in-app purchases: Relativistic Space at none against Formula Conversion's 1. Formula Conversion's advantage is update cadence (every 26 months vs every 75 months). On price, ads, device support and iOS requirement there is nothing between them.
