ArrowCluster

ArrowCluster keeps an archery practice round on one target. Tap where each arrow landed, and the app turns that mark into a score, an end total, and a session total. The face is a full ten-ring target. Rings 10 and 9 are yellow, 8 and 7 red, 6 and 5 blue, 4 and 3 black, and 2 and 1 white. A mark on a ring boundary takes the higher score. An inner ten can be counted as an X without adding an extra point. A miss is stored as zero and stays out of the group. You can zoom, pan, move a marker, or type a different score when the shaft touches a line. The saved position stays in target coordinates. When an end is finished, ArrowCluster shows the end score, average, hits, group diameter, mean radial deviation, and how far the cluster sits from center. Direction is read from the group center: high, low, left, right, or a corner. Later sessions at the same distance and face can be compared with an earlier round when both have a real group. The range log lists every session with its date, distance, face, score, and a small target. Filters cover live and finished rounds, distance, and equipment. Insights chart average score, hit rate, and group diameter, plot impacts from several sessions, and summarize results by distance and by bow or arrow set. Gear holds bows, arrow sets, and named setups such as an indoor hall combination. A change journal records draw weight, point weight, and similar adjustments without dropping old sessions. Drills open a real shooting session for center control, a tight group, a consistency ladder, or a distance progression. Export one session or the whole archive as a spreadsheet, a structured backup, or a printable report. Sample rounds can be loaded to explore the screens, and they stay out of your averages until you choose to count them.
