HoldIT Jack is a clean, full feature private retention tracker designed for men who want to build discipline and stay consistent with their practice whether you’re doing semen retention or simply working on stronger self-control. Track your streak, log daily energy and urges, complete guided kegel sessions, and watch your progress with clear trends and milestone badges, all stored securely on your device with NO ACCOUNTS, NO ADS, and NO SUBSCRIPTIONS. Semen retention has long been practiced across different traditions as a way to cultivate focus, mindfulness, energy and personal power. HoldIT Jack gives you a simple, judgment-free tool to track it on your own terms, so you can stay motivated and own your progress without anyone else watching. PAY ONCE. OWN IT FOREVER. • One simple price unlocks the entire app — every feature, forever. • No subscriptions. No in-app purchases. No "premium" tier. No paywall hiding the best parts. What you see is everything you get. • All future updates and new features are included free, for good — buy it once and it only gets better. • A premium, polished app at a low, one-time price. Built to respect your money and your time. PRIVATE BY DESIGN — THIS IS THE WHOLE POINT • No account. No sign-up. No email required — you deserve what you purchase. • No ads. Not now, not ever — the product is yours. • No cloud and no servers — your data is not indexed globally. • No tracking, no analytics, no data collection of any kind — no prying eyes. • 100% of your data stays on your device. We never see it, we don't want to see it, and there's nothing to leak, sell, or lose. TRACK WHAT MATTERS • Start and stop a session with a single tap and watch your day count climb. • Log your daily Energy, Release Urges, and Hardness on a simple Low / Medium / High scale — it takes seconds. • Log Kegels and Release Control (intimacy without release) with a tap. • Back-date any day within your current streak if you forget to log. • Follow your own trend charts over your streak — let the direction of the line be your motivation: your numbers, your progress, in plain sight. RELEASE PASSES — YOUR STREAK, YOUR RULES • Allot 0–5 "release passes" when you start a session — playful little tickets that let you release once and keep your streak running. • Tap a ticket to use a pass; it's logged and marked used, in order. Your day count is never reset by using one — it's an honest, judgment-free way to stay on track instead of starting over. INSIGHTS & BADGES THAT KEEP YOU GOING • Clear insights: current streak, best ever, total sessions, average session, and kegel rate. • Session-trend arrows and per-metric charts show whether Energy, Urges, and Hardness are climbing. • A 14-day conditioning view of your kegels and Release Control at a glance. • Earn badges across Retention, Kegel Mastery, and Release Control tracks as you hit milestones — small wins that add up, with a celebration each time. GUIDED KEGEL EXERCISES • Built-in guided kegel sessions with on-screen squeeze-and-relax timing. A REMINDER ON YOUR SCHEDULE • Choose your own daily reminder time — we'll nudge you to log when it suits you. HOME & LOCK SCREEN WIDGET • Add the Retention Streak widget to your Home Screen or Lock Screen. HISTORY THAT STAYS WITH YOU • Lifetime totals and every past session, with retained stats per session. • Your complete history — including an in-progress streak — carries over automatically when you update the app or move to a new iPhone. Nothing is ever lost. • Export everything to a CSV file in one tap • Want it gone? Delete the app and it's totally gone. You're always in control. • Want added privacy? Lock the app behind native iOS Face ID or Touch ID. LOOKS GREAT DAY OR NIGHT • Full Light and Dark Mode support SIMPLE, FAST, DISTRACTION-FREE • Lightweight, native, and beautifully focused — no clutter, no noise. HoldIT Jack is a wellness and self-tracking app. It is not medical advice.
