StepOpen is the "walk to unlock" app. Lock the apps that distract you (social, video, games) and unlock them once you reach today's step goal. The more you walk, the more of the time your phone was taking comes back to you. Instead of guilt or pressure, it turns moving your body into the "key" - a gentle digital detox habit. It's simple 1. Choose the apps you want to lock 2. Set the steps needed to unlock them (2,000 / 3,000 / 5,000 / 8,000) 3. Until you reach that count, the chosen apps stay locked 4.

PepLog is a medication reminder & logbook for people who manage a peptide protocol and want to keep track of their progress & history. It's built around one idea: recording a dose should take seconds, right when it happens, the way a food tracker works. WHAT YOU CAN DO • Log a dose in a couple of taps: amount, time, injection site, and a note • Reconstitution made clear: enter a vial's contents and the water you added, and PepLog derives the concentration and converts the dose amount you enter into syringe units • Track your vials: see how much you have left as you log, when each vial was mixed, how long ago, and what 1 mg measures in it. Finished vials remain in your history • Progress photos: capture on a repeatable angle, compare any two side by side, and watch your timeline build over months • See what you've invested: record what a vial cost and PepLog shows your real spend, your cost per logged dose, and how much of what you mixed you've used • Set reminders on your own schedule, with multiple times a day, and log or snooze straight from the notification • See your consistency: a logging streak, badges, a week view, and a history of everything you've recorded • Track your weight and hydration over time, with your own optional goals NEW IN 1.4.2 - A fresh turquoise design throughout PepLog, with light and dark mode, an updated app icon, and refreshed logos. - Tap the sun or moon next to your profile to switch themes, or tap your profile to open Settings directly. - Vial details show when you mixed, time since mixing, and what 1 mg measures in syringe units. - Stats now defaults to 30 days with a cleaner layout. - Additional injection-site choices include left and right waist and lat, and Sign in with Apple reliability has been improved.

Verdict
The clearest difference is in-app purchases: PepLog at none against StepOpen's 4. StepOpen's advantage is update cadence (daily vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
