Mesos
Read full descriptionHide full description
Mesos is a mesocycle programmer for lifters who already train by volume landmarks and RIR. It builds a hypertrophy block, adds volume week to week, calls your deload, and — unlike most apps — shows you why it made each call. Programming you can audit Most autoregulation tools hand you a number and ask you to trust it. Mesos shows its work. Every time it adjusts your sets, it tells you what it read from your logs — your RIR, your soreness, your performance trend — and how that maps to a volume change. If you disagree, you override it. The app adapts to your decision; it doesn't argue. Built around volume landmarks Set your MEV (minimum effective volume) and MRV (maximum recoverable volume) per muscle group, or start from sensible defaults and tune as you go. Mesos starts each muscle near its MEV and progresses toward MRV across the block, then deloads before recovery debt stalls your progress. RIR-driven progression Log each set with reps, load, and reps in reserve. Mesos reads the trend across sessions and adjusts the next week's volume from your actual performance — not a fixed template. Sets get added when you're recovering well, held when you're not, and pulled back when the data says you're at your ceiling. Deloads when you need them, not on a fixed calendar The app watches for the signals that precede a stall — rising RIR at the same load, soreness that doesn't clear, performance flattening — and proposes a deload when they accumulate. You confirm or push the block one more week. Your call, with the evidence in front of you. A logger that stays out of the way The free tier is a full training logger: exercises, sets, reps, load, RIR, and per-muscle volume totals. No trial timer, no nag screens. Log your training as long as you like. Upgrade only when you want the programmer to plan and autoregulate the block for you. Free tier - Full set and session logger - Per-muscle weekly volume totals - MEV/MRV reference per muscle group Mesos Pro ($9.99/month or $69.99/year, 7-day free trial on yearly) - Automated mesocycle programming, MEV to MRV - RIR-based weekly volume autoregulation - Deload detection with explained reasoning - Per-set and per-muscle progression history - Full manual override on every recommendation Built for intermediate and advanced lifters who train by the numbers. If you already think in volume landmarks, RIR targets, and recoverable volume, Mesos speaks your language.

Sunnah Lock helps you guard your time and lower your gaze by blocking distracting apps, websites, and whole categories — enforced by iOS itself, not a workaround you can talk yourself out of. PRAYER-TIME BLOCKING Distractions lock automatically across each of the five daily prayer windows, calculated on your device from your city. No account, no location tracking — just a name and a time. BUILD YOUR OWN BLOCKS Guard a time, a place, or a habit. Start from a ready-made template — Masjid, Home, Night, Work, Seeking Knowledge — or build your own from scratch: pick the apps, set the schedule, done. MUHASABAH — YOUR OWN HONEST RECORD See your real screen time, straight from Apple's own Screen Time data — never estimated, never invented. Your weekly pattern, your most-used apps, and the apps quietly running above their usual pace. Nothing here is guessed, and nothing leaves your device. BLOCK HARAM CONTENT Apple's own adult-content filter plus your own website list, on all day, everywhere — not just during a scheduled block. ADHKAR Morning and evening remembrance, in Arabic, transliteration, and translation, every entry sourced. Sign-in is optional — the app works fully without an account, and creating one only saves your plan across devices. Built for the moments your phone gets between you and what actually matters. SUBSCRIPTION Sunnah Lock Premium is available monthly or yearly, each with a 7-day free trial. Payment is charged to your Apple Account when the trial ends. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. You can manage or cancel it at any time in your Apple Account settings.

Verdict
The clearest difference is device support: Mesos at 3 against Sunnah Lock's 1. Mesos also leads on iOS requirement (13.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.
