About

VOID

Read full description

Most gym apps are dark and busy. VOID isn't. I designed it to make logging easier, not harder. Log one set. It grows from there. WHAT I PUT IN It does what a workout log should do. Logging — Weight, reps, and set count, grouped by exercise. Add, edit, or delete. History — A calendar shows which days you trained. Pick a date to see that day's sets, and add, edit, or delete just like today's log. Widget — Put that calendar on your home screen. Small, medium, or large. Progress — See trends in training frequency, sets, volume, and heaviest weight. View them overall, by category, or by exercise. Categories and exercises — Common exercises are there from the start. Add, rename, delete, and reorder them, so bodyweight and machine exercises fit too. Buttons — Set your own weight and rep increments. Units — kg or lb. Theme — Light or dark. Backup — Export your records to a file and restore them later. CSV — Export your records as a CSV file. HOW IT WORKS Pick an exercise and the weight and reps from your last session with it are already filled in. The more you log, the less there is to enter. To change them, use the buttons along the bottom of the screen. No keyboard appears — the only exception is naming an exercise you add yourself. When the numbers are right, swipe them up. That saves the set. There is no save button. The numbers stay where they are, so another set at the same weight is one more swipe. Weight can stay at 0 kg. That's for bodyweight exercises. Swipe sideways from either edge of the screen to move between logging, today, progress, and history. WHAT I LEFT OUT Logging is still at the core. · Rest timer · Notes · Routines and programs · Goals and personal records · Body weight and body fat · Apple Health Not because I couldn't build them. I decided they weren't needed. The rest timer and notes were the two I went back and forth on. If there's something you want, tell me. I read everything. NO ADS. NO NOTIFICATIONS. NO SIGN-UP. NO SYNC. You won't see an ad. You won't get a notification. There is no account to create and no email address to give. Nothing syncs anywhere. Your records are stored on this device. PAID FEATURES Progress and CSV export unlock with a one-time purchase. Not a subscription. Everything else is free, with no time limit. FROM THE DEVELOPER I build apps on my own. I tried a lot of workout apps, and they all seemed to be heading in the same direction. Dark screens, packed with information, complicated to look at. For people who already know what they're doing, that may work well. For someone just starting, or someone who only trains now and then, I thought it probably didn't. So I built this by taking things away instead of adding them — a different shape for a workout app. If it isn't for you, that's a shame — but don't feel bad about dropping it. Another app, pen and paper, or nothing at all — just keep training.
