This is your Guest Pass - Discover gyms worth finding. Guest Pass is a curated gym discovery app built to help you find unique, independently owned gyms, purchase a pass, and start training with more freedom. Instead of trying to list every gym everywhere, Guest Pass focuses on finding the hidden gems. The independent gyms with character, great equipment, passionate owners, strong communities, and something that makes them worth discovering. Whether you are traveling, new to an area, or simply looking for somewhere different to train, Guest Pass makes it easier to find a gym that fits what you are looking for. Explore our curated directory, learn about each gym, see photos and important facility information, and find gyms you may never have discovered otherwise. At participating locations, you can purchase a Guest Pass directly through the app and redeem it at the gym using a secure, unique QR code. No membership or long-term contract required. VERIFIED BY GUEST PASS Look for the Guest Pass Verified badge. Verified gyms are facilities that the Guest Pass team has physically visited and toured as part of the complementary Guest Pass gym tour series hosted by Guest Pass creator David Ziegler, the "Ziegler Monster", giving you another way to discover gyms we have experienced firsthand. FOR GYM OWNERS Guest Pass is built to support independently owned gyms and the people behind them. If your gym is not currently listed, you can submit it for consideration. Because Guest Pass is a curated directory, listings are reviewed and created by our team rather than automatically added to a massive database. Already see your gym on Guest Pass? Simply create your free account, find your gym, and claim the existing profile. Once claimed, you can manage your gym’s information and keep your listing accurate and up to date. Gym owners can also opt into digital Guest Pass sales, allowing visitors to purchase access through the app and redeem their pass at check-in with a secure QR code. It is an easy way to welcome new visitors and create an additional revenue stream with unlimited earning potential. Guest Pass is free to download and free for gyms to use. FIND GREAT GYMS.

Whether you're optimizing for fat loss, muscle gain, longevity, recovery or anti aging, Milligram is for people who want to take back control of their health protocols with science-backed confidence. Every other tracker gives you a tidier place to write down what you already did. Milligram models what is actually in your system right now. Every dose charted against every half-life. Everything in the stack with info and the database covering over 3,581 references total. Bloodwork read against what you are actually running. And an AI assistant that answers from your real-time numbers, read against a database made specifically for your protocol, not everyday questions. FEATURES Your Protocol: Everything you run, on one screen. Each compound with its own schedule, dose, vial and supply tracked, and the whole protocol read as one picture rather than being scattered across different notes, files and spreadsheets. Dose tracking: Log every dose, whether that's an injectable or an oral supplement - Milligram works with every compound and every dosing route. Reminders arrive on the protocol's schedule and know which compound, which dose and which injection site. Reconstitution Calculator: Mix any vial, any concentration. Convert mg, mcg, IU, and units for compound preparation. Designed for accurately mixing peptide vials with bacteriostatic water - saved to your compounds for quick reference. Milligram Intelligence: An assistant that already has your stack, your doses, your bloodwork and your Apple Health data loaded. Ask "what do I draw for 5mg from a 10mg vial in 2ml", "how is my weight tracking against my retatrutide cycle", or "did my IGF-1 move on tesamorelin", and get an answer from your own numbers. Level Buildup: See your compound levels build from each trough to peak. Every dose is charted against the published half-life of your compound, so you know exactly when you've reached the right zone at the right titration, how each dose is keeping you there, and how much a missed dose can actually move the needle. Bloodwork: Upload a PDF or a photo of your labs. Every biomarker is extracted and out-of-range values flagged, then kept where they can be read against the compounds that might be moving them. Compound Library: 202 compounds with mechanisms, dose ranges, half-lives, expected timelines and side-effect profiles, each referenced to clinical sources. Retatrutide, tirzepatide and semaglutide. Testosterone esters, Masteron, Anavar. Tesamorelin, BPC-157, GHK-Cu, MK-677, Ipamorelin and CJC-1295. Creatine, Omega-3 Fish Oil, Magnesium, Zinc, Vitamin D3, and more. AI calorie and nutrition tracking: Scan any meal with your camera. Snap a photo, scan a barcode, or scan a nutrition label and Milligram extracts calories, protein, carbs and fat instantly. Track every meal against your daily targets with a clean macro breakdown. Apple Health: Two-way sync for sleep, HRV, vitals, activity, weight and body composition, so protocol data and health data sit in the same timeline.
