About this app

LiftLab is a workout tracker, gym log, and strength training planner for lifters who want to build detailed gym programs instead of forcing every session into a fixed template.

Build Custom Programs
Create training plans from scratch with weeks, workout days, blocks, exercises, sets, rep ranges, RIR targets, rest times, and progression rules. LiftLab is built for people who already think in programs: strength blocks, hypertrophy phases, volume ramps, deload weeks, and accessory work all fit in the same planner.

Track Workouts Without Rebuilding Your Plan
Open the next scheduled session, log weights and reps, use the rest timer, and finish with a clear workout summary. The app keeps your program structure intact while letting you record what actually happened in the gym, so your workout log stays connected to the plan that produced it.

Progressive Overload, Deloads, and Training Maxes
Set training maxes per exercise and choose how each block progresses over time. LiftLab can calculate target loads, apply weight increases, round loads by exercise increment, and manage deload weeks from the rules you configure. Use simple linear progression, wave loading, volume ramps, or flat set targets depending on how you train.

Program Builder for Real Gym Details
Configure barbell, dumbbell, cable, machine, bodyweight, and other exercise types with their own weight increments. Organize exercises by muscle group, build supersets or multiple blocks, adjust set ranges, and keep kg or lbs display aligned with your preference.

Program Catalog You Control
Browse ready-to-download strength and hypertrophy programs, preview the plan before you add it, then customize the downloaded copy with the same editor. LiftLab starts clean: create your own plan or download only the programs you want.

Private by Default
You can train without creating an account. Your custom plans, downloaded program copies, and workout history stay on your device. Internet access is used for Google Play app update checks, program catalog downloads, announcements, and bug/crash reporting.
