Settings, Personalization & Support

By NexusWorks · Updated July 2026 · 6 min read

The Settings tab is deliberately small — a lift log should spend its screen time on lifting. This page is the reference for everything in it: appearance and language, how units actually work, where to rate the app or request a feature, how to reach support, and the safeguards standing behind your data.

Appearance

Herculog offers three appearance modes: System, Light, and Dark. System is the default and follows your iPhone's own light/dark schedule — the app switches when iOS does, so if your phone goes dark at sunset, so does your log. Pick Light or Dark instead to lock Herculog to one look regardless of what the rest of your phone is doing — useful if you always train in a dim garage gym, or simply prefer one mode everywhere. The choice applies across the whole app, every tab and every screen, the moment you make it.

Language

The language setting offers System, English, Français, and Español. System follows your device language; the explicit options override it just for Herculog, so your phone can stay in one language while your lift log speaks another. The change takes effect right in the app — no trip to iOS Settings needed.

Two things worth knowing:

• Date and number formats follow the language you choose — switch to Français and dates and decimals render the French way throughout the app.
• The list also hides a small surprise for the observant. We won't spoil it — scroll with intent.

Units: there is no global switch

People look in Settings for a kg/lb toggle. It isn't there — on purpose. In Herculog, the unit is set per entry with the Metric chip on the Add form, not globally. Each logged entry carries its own unit, so you can log dumbbells in pounds at one gym and plates in kilos at another without converting anything in your head, and your history stays exactly as you lifted it. Summaries and charts sort out the mixing for you. So if you were hunting Settings for the unit switch: it lives on the Add form, one tap away every time you log.

Review & Support

The Review & Support section gathers everything between you and us:

• Submit Rating. Rate Herculog on the App Store. The app is free with no ads, so honest ratings are genuinely how it finds new lifters.
• Feature Request. Opens the feature board at herculog.com/features, where you can propose ideas, see what other lifters have asked for, and vote on what gets built next. If Herculog is missing something you'd use every session, this is the fastest way to say so.
• Support email. Something broken, confusing, or behaving oddly? Email support straight from the app. Include what you did, what you expected, and your app version (see below) — that combination usually gets you an answer in one round trip.
• Welcome Screen. Replays the welcome screen from first launch — the quick tour of fast logging, PR tracking, guided plans, and privacy — any time you want a refresher or want to show someone what the app does.

Privacy & your data

Herculog is local-only: your data is stored on your device and nowhere else. There is no account to create, no login to remember, no cloud service holding a copy, and nothing leaving your phone. Your training history — every set, every PR, every note — exists in exactly one place, and you own it. Full details are in the privacy policy, which is short because there's little to disclose.

The honest trade-off: no cloud copy means backups are in your hands. Exporting a CSV to Files or iCloud Drive now and then is all it takes — the backup and export guide walks through the whole routine, including moving to a new phone.

The app also protects your data on its own in two ways:

• Automatic backups before data-format upgrades. When an app update needs to change how your data is stored, Herculog backs your data up automatically before touching anything.
• The "Data Unavailable" safeguard. If the app ever can't read your data safely, it stops and tells you rather than proceeding and risking damage to your log.

Finding your app version

Scroll to the bottom of the Settings tab — the app version is shown in the footer. It's easy to overlook and worth knowing about: when you contact support or file a bug, mentioning the exact version you're running is often the difference between one email and three, because it tells us immediately whether you're seeing something already fixed in an update.
