This level is different! It plays tones when level so you can HEAR that sweet sound of Level. No more running back and forth, squinting at a bubble level, or needing a partner to check for accuracy while you make adjustments. Sure, there are other level apps, but none like ToneLevel. Not only does it let you HEAR when you’re level, but it also offers a selection of cool faces to match your leveling style. Plus, ToneLevel lets you adjust the precision to fit your needs, whether you’re aiming for exactness or just “close enough.” When you’re within your chosen sensitivity range, ToneLevel will start playing tones sooner, so you’ll know you’re spot on.
