Simple Protein is an easy way, the easiest way, to track your daily protein intake only. It doesn't track fat or carbs. Why? Because if you want to build muscles protein matters much more than fat or carbs. In tests lasting months, we've found better results by hyper-focusing on tracking protein ONLY while remaining smart and conscious about fat and carb intake. In other words: don't overdo the fat or carbs, keep it smart. But do get very focused on your protein intake. You'll likely see results too. Simple Protein is simply a simple protein tracker. DAILY LOG - track your grams of protein consumed each day. You can add days too if you have some historical data you want to put inside of Simple Protein. STATISTICS - See multiple metrics over a variety of time frames. It's a quick way to see if you are on track and hitting your daily protein target. TARGET - You can enter and edit your own daily protein target at any time. Or you can use our smart protein target calculator. It considers age, gender, height, weight, activity level, goal, and can use two different BMR formulas. You can also adjust the app for light or dark appearance, imperial or metric units, and turn Decimal Precision on or off. If you want to unlock ALL features, you can pay a simple, cheap, one-time purchase. If you don't mind the restrictions within the app, you can use it for free forever.
AltLog
Read full descriptionHide full description
AltLog is a one-tap elevation logger. It reads the barometric pressure sensor built into your iPhone and turns it into a live tally of height climbed, height descended and stair-equivalents — in metres or feet. There is no GPS. None. AltLog never asks for your location, and the pressure sensor uses far less power than GPS. WHEN IT WORKS • Inside parking garages, multi-story buildings and stairwells where GPS is useless. • On stairs, hills and short climbs where you want the number, not a map. • In elevators — see how much height the ride really covered. • Anywhere there is air. (Sealed pressurised vehicles excepted — physics, not us.) HOW TO USE 1. Tap Start before a staircase, a hill or a walk. 2. Keep AltLog open: it measures while it is on screen, and it keeps the screen awake during a session. 3. Tap Stop when you're done. The session lands in History with its altitude profile. WHAT YOU GET • Live cumulative ascent, in metres or feet, and in stair-equivalents (1 stair = 0.20 m). • Cumulative descent, counted separately from the climb. • An altitude profile chart for each session, kept in History. • The height unit follows your region, or your own choice in Settings. FREE AND PRO Recording sessions is free, and your three most recent sessions are always there. AltLog Pro, a one-time in-app purchase, unlocks your full session history. PRIVATE BY DESIGN No account. No cloud. No ads, no tracking. Pressure samples are processed on-device, and your sessions are stored only on your iPhone. Deleting the app removes everything.

Verdict
The clearest difference is in-app purchases: AltLog at none against Simple Protein's 1. AltLog also leads on update cadence (every 2 weeks vs every 5 weeks). Simple Protein's advantage is iOS requirement (16.0 vs 18.0). On price, ads and device support there is nothing between them.
