A gym workout log for lifters who train by effort. Log weight, reps and reps in reserve (RIR) in seconds, and see exactly what you did last time. NotchLift tracks progressive overload the honest way: a record only counts when the effort backs it up. Effort is tracked in reps in reserve (RIR), the scale used in strength-training research. Estimated 1RM averages the established Epley, Brzycki and Lombardi formulas, adjusted for how many reps you had left. WHAT'S FREE — AND STAYS FREE • Unlimited logging, full history, no ads, no account. • Your last session for every exercise, visible while you log the next one. No scrolling through a notes app to find it. • A photo for every exercise, and its how-to one tap away on the name. • Custom exercises that fit your program, not the other way around. • Forgot to hit Finish? Set the time you actually trained, after the fact. • Import from CSV. Export to CSV, always. Your sets are yours — never locked. • Deloads are planned, not punished. Log 30 lbs less and nothing complains. WHAT PRO ADDS Pro is the analysis layer. Your data is never gated — only the lens. • All-time trends across eight views: strength, volume, effort, records, body, fatigue, notes, exercises. • Readiness that suggests when to push. Suggests. Your program stays yours. • Cut report: dropping weight while keeping strength, on record. • Muscle coverage: which muscles your week actually trained. • PR ladders and estimated 1RM trends across your entire history. WHAT'S NOT HERE No confetti over nothing, no streak guilt. There is no feed and nothing to follow. Logging a set takes seconds, because that is the whole point. WHO IT'S FOR Lifters coming from Apple Notes, or from a spreadsheet that hangs mid-set. Lifters tired of free plans that break their program. Anyone who wants to know two things: what did I do last time, and is it working. Start from your next set, or import your history. If you ever leave, everything exports with you. NotchLift Pro is available as a monthly or annual subscription. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
SelfAssay

SelfAssay is a research workspace for people who self-experiment with supplements, peptides, and nootropics. Look up the evidence, then find out with your own data whether your stack is actually working for you. IMPORTANT SelfAssay is decision support for your own research. It is not medical advice and does not diagnose, treat, cure, or prevent any disease. It does not sell, source, or recommend any compound, and it does not encourage the acquisition or use of any substance, including prescription or research compounds. Always consult a qualified clinician and follow the laws where you live. LOOK UP ANY COMPOUND Search a growing index of 500+ compounds. Each dossier shows an effectiveness grade by purpose (sleep, focus, recovery, fat loss, and more) and a separate safety grade, both computed from thousands of classified first-hand community reports. See the most-reported effects and side-effects, cited studies and clinical trials, and clinical biomarker directions. When there is not enough first-hand data yet, you see a dash. We never guess. TRACK YOUR OWN STACK Log the compounds you take with dose and schedule, run daily check-ins for energy, focus, mood, and sleep, and set up simple n-of-1 experiments. Connect Apple Health to layer your sleep, HRV, and resting heart rate onto the days you took a compound versus the days you did not. The correlation is computed entirely on your device. MORE TOOLS - Companion: an AI assistant for compound questions, grounded in the dossier data so it refuses rather than fabricates. - Pre-Flight: surfaces interaction and safety considerations reported in the community and the literature for a planned stack, as information to review with a qualified clinician. - Decoder: organizes the values from your own lab report for your reference and lines them up against your stack. It does not diagnose or interpret your results. - Protocols: save and revisit structured protocols. PRIVATE BY DESIGN Your vault is encrypted at rest. Apple Health data stays on your device and is never sent to our servers. There is no third-party analytics and no tracking. Export or permanently delete your account and data anytime from the app. FREE TO USE Core research and tracking are free to use. Companion, Pre-Flight, and Decoder have free limits, and advanced use is part of SelfAssay Pro.

Verdict
The clearest difference is update cadence: NotchLift at every 4 days against SelfAssay's every 10 days. SelfAssay's advantage is iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
