LockIn30 vs Habit Tracker by Inner Grow Limited

Quick answer

Habit Tracker by Inner Grow Limited, whose listing also writes the developer as InnerGrow, is a daily planner for building routines and quitting bad ones. It has been on the App Store since 2019, runs on iPhone, iPad, and Apple Watch, and was last updated in August 2026 at version 2.14.23. The catch is that nothing on the store page describes a challenge with a start and an end, and nothing on it explains what any of its six in-app purchases buys.

LockIn30 runs one habit as a fixed-length challenge: pick from a 36-task library across 12 categories or write your own, set any duration from 7 to 365 days, and log it once a day. It is free to download and needs no account. It also works offline.

If you want one app to hold several routines, mood entries, Apple Health data, and an Apple Watch app, pick Habit Tracker (Inner Grow). If you want a single habit with a finish line, a rule for missed days, and photos that turn into a timelapse, pick LockIn30.

Side-by-side

Where Habit Tracker by Inner Grow Limited wins

Its rating rests on real volume built up since 2019. Habit Tracker (Inner Grow) has been on the App Store since January 2019 and carries 4.8 stars from 146,800 ratings. LockIn30 was released in May 2026 and has 3 ratings. If you want an app that thousands of people have already argued about in public, that gap is the whole story.

You can buy it once instead of renting it. The store page lists Lifetime Member at $9.89 and Lifetime Family at $12.99 next to Monthly Premium at $2.99 and Habit Premium Yearly at $7.99. Reviewers repeatedly name the one-time purchase as the reason they chose it over subscription rivals. LockIn30 sells Pro only as a weekly or annual subscription.

It covers far more ground than one habit. The listing names Apple Health sync for water, steps, sleep, exercise, and calories; an HRV stress monitor; mood tracking; a habit diary; a focus timer; a biometric lock; Home Screen and Lock Screen widgets you can log from without opening the app; an Apple Watch app; and Shortcuts support added in August 2026. Some reviewers say the widget is where they actually log. It also ships in 11 languages against LockIn30’s one. Its listing does name Group Habits and Friendly Competition for shared habits, but reviewers report that feature failing, so treat it as unproven.

Its privacy label is the cleaner of the two. Habit Tracker (Inner Grow) declares one thing: Diagnostics collected for analytics and not linked to you. There is no “Data Used to Track You” section and no “Data Linked to You” section. LockIn30’s label declares “Data Used to Track You: Identifiers”, which is the worse line of the two even though LockIn30 carries no ads.

Where LockIn30 wins

Habit Tracker (Inner Grow) sets no run length on its listing, so a challenge is something you improvise. Its store page describes no duration picker, no start-and-end run, and no 30-day or 75-day preset. The custom repeat interval added in July 2026 sets how often a habit repeats, not how long the run lasts. Some reviewers mention using the app to run 75 Hard. LockIn30 asks for a duration up front, anywhere from 7 to 365 days with 30 as the default, and counts down to a finish line with half-way, three-quarters, and completion milestones.

Nothing on the Habit Tracker (Inner Grow) listing says what happens when you miss a day. No strict mode, no grace day, no honesty prompt. One reviewer describes a skip feature that keeps streaks from resetting, and that is the whole of the evidence. LockIn30 makes the missed day a decision you take at setup: tough mode with a Be Honest dialog, or soft mode with no penalty. Behind that sit a once-per-device auto-fill rescue, a restart that bumps an attempt counter instead of hiding the failed run, and, as of the August 2026 update, missed days grouped into date ranges.

Photos are absent from the Habit Tracker (Inner Grow) listing, and they are the point of LockIn30. Progress photos and any recap video are not stated on its store page, and one reviewer notes they would rate it higher if a picture could be attached to a habit. LockIn30 lists photo capture with day numbers, a gallery organized by day, side-by-side compare, and a 1080x1920 timelapse at 4 FPS that saves to your gallery or shares. Photo is one of six input types, alongside checkbox, counter, duration, text, and measurement.

Habit Tracker (Inner Grow) hands you a blank field, and no Google Play listing was found for it. No preset habit library or task catalogue is stated on its listing, and one reviewer calls it basically a blank slate. LockIn30 opens with a survey that suggests a habit and a 36-task library across 12 categories, including fitness, nutrition, sleep, learning, and hydration, plus a custom option. It also has a Google Play listing at com.ehmtech.lock, while no Google Play listing was found for Inner Grow Limited.

Pricing

• LockIn30 is free to download, with no ads and no account. Pro is $2.99 a week or $29.99 a year, with a 7-day trial. The listing does not spell out what Pro unlocks, so we will not claim a split the store page does not state.
• Habit Tracker by Inner Grow Limited is free to download. The store page lists six in-app purchases: Lifetime Member $9.89, Lifetime Family $12.99, Habit Premium Yearly $7.99, Habit Promo $7.99, Enhance Yourself $5.99, and Monthly Premium $2.99. What Premium adds is not spelled out on the store page, and the listing does not state a trial. Two of those names, Habit Promo and Enhance Yourself, are never explained. The $7.99 year costs less than three months of the $2.99 monthly plan. Reviewers report the free edition stops at about six habits, though a few name other figures.

For one year, that is $29.99 for LockIn30 Pro against $7.99 for Habit Premium Yearly, or $9.89 once for Lifetime Member. On price alone Habit Tracker (Inner Grow) is the cheaper year by a wide margin.

Which one should you pick?

Pick Habit Tracker by Inner Grow Limited if you want to track several habits at once, sync them with Apple Health, log from a widget or an Apple Watch, read weekly and monthly reports, and pay once instead of subscribing.
