You don't need a gym to look bigger in your clothes. VTaper is a 90-day at-home challenge that trains only the muscles that actually show in a fitted shirt — shoulders, upper chest, arms and upper back. No legs. No abs. No equipment. Just the frame people see. About 12 minutes a day. VTaper Pro is a paid auto-renewing subscription. A subscription is required to unlock the 90-day program and all of the features listed below. New subscribers can start with a 7-day free trial on the yearly plan. THE PROOF IS YOUR OWN PHOTO Take one photo a day in a fixed frame. VTaper builds it into a before-and-after you can actually see. Because change is invisible day to day, we only reveal your progress weekly — and at Day 30, 60 and 90 — when it's real. WHAT'S INCLUDED IN VTAPER PRO (paid subscription required) • A daily 12-minute bodyweight session. No gym, no equipment. • Your own before-and-after, shot in your best light • Day-1 "Look Bigger Now" — shirt fit, posture and camera tricks that work in five minutes • A streak that survives real life, with flex days • Three progressive 30-day blocks, so it never goes stale • An optional resistance-band track if you want shoulder width too HONEST ABOUT RESULTS Bodyweight training fills out your chest, arms, back and posture — the V-taper illusion that makes a t-shirt sit right. Shoulder width is load-dependent, so that's what the optional band track is for. We tell you which is which. SUBSCRIPTION DETAILS • VTaper Pro Yearly — $49.99 per year, including a 7-day free trial for new subscribers • VTaper Pro Monthly — $9.99 per month • Prices are in U.S. dollars and may vary by country. Your local price is always shown in the app before you confirm any purchase. • Payment is charged to your Apple Account at confirmation of purchase. • Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. • Your account is charged for renewal within 24 hours prior to the end of the current period, at the price of the plan you selected. • You can manage your subscription and turn off auto-renew at any time in your Apple Account settings after purchase. • If you start a free trial, any unused portion of that trial is forfeited when you purchase a subscription.

Verdict
The clearest difference is device support: Heft at 3 against Build muscle's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.
