GLPily vs Shotsy vs MeAgain: A Fair 7-Day Test-Drive Scorecard

GLPily vs Shotsy vs MeAgain: which GLP-1 tracker is best? The honest answer is the one that fits your week. Feature lists overlap a lot, so the fairest way to choose is to test each app for seven days with the same real entries, then score them on the same card. This guide gives you that method and a scorecard you can copy.

Full disclosure: we make GLPily. That is exactly why this page is a method, not a verdict. If you want a snapshot of what each app offers and costs, our roundup of the best GLP-1 tracker apps in 2026 lists GLPily, Shotsy, MeAgain and four others, checked against their store pages in October 2026. Come back here to decide.

Why test-drive instead of reading reviews?

Reviews tell you about someone else's routine. A star rating cannot tell you whether you will find the shot log in two taps, whether reminders survive your phone's battery settings, or whether the food logger understands your lunch.

Research on self-monitoring backs this up. In a two-year randomized trial of paper versus electronic tracking for weight loss, how consistently people logged mattered more than which tool they used. The best app is the one you keep opening.

How to set up a fair test

A few ground rules keep the comparison honest:

• Same week, same phone. Install two or three apps at once. Testing one in January and one in March is not a fair fight.
• Same entries everywhere. Log your real shot, weight and symptoms in each app. Yes, it is triple data entry for a week. That is the point.
• Free tier first. Score each app on what is free, then decide whether a paid tier earns a separate score.
• Write down trial end dates. On iPhone, Apple says to cancel a free trial at least 24 hours before it ends if you do not want it to renew.
• Skip what you won't use. If you never plan to scan food, do not let a fancy scanner sway your score.

The 7-day test drive

Day 1: Setup and first impressions

Install, create accounts and get through onboarding. Note what each app asks for before you can start. Did it demand data you did not want to give? Read the store privacy label too. Our 5-minute privacy scorecard makes that quick.

Day 2: Log a dose and set a reminder

Log your most recent dose (or a test entry you delete later) and set up your shot-day reminder. Time how long it takes. Note whether injection site rotation is there if you use injections.

Day 3: Log food the way you actually eat

Log one real meal in each app: a search, a barcode, or a photo scan if offered. Is the result close to what you ate? How long did correcting it take?

Day 4: Log a symptom and a check-in

Log a side effect with a severity, or a "feeling fine" day. Can you add a note? Is it easy to see later?

Day 5: Try to get your data out

Find the export. Is there a CSV, a PDF report, or nothing? Open the file. Would it help at an appointment? Our export and deletion checklist lists what to look for.

Day 6: Real-life stress test

Did your Day 2 reminder actually arrive? Open each app with weak signal. If you have an iPad or second phone, check whether data syncs. Try health sync (Apple Health or Health Connect) if you care about it.

Day 7: Look back and score

Open each app's charts and history. Which one tells you something useful about your week in ten seconds? Then fill in the scorecard.

The scorecard (copy this)

Score each row from 1 (frustrating) to 5 (delightful). Multiply by the weight, which you set from 0 (don't care) to 3 (essential).

What you're scoring	Weight (0–3)	App A	App B	App C
Logging a dose: speed and clarity
Reminders actually arrived on time
Injection site rotation (if you inject)
Weight and progress charts you understand
Symptom and side-effect logging
Food logging accuracy and effort
Export you could hand to a clinician
Privacy label and policy clarity
Works on all your devices and in your language
Free tier covers what you need
Paid tier worth it to you (if relevant)
How it made you feel (calm vs nagged)
Weighted total

That last row is not fluff. An app that leaves you feeling judged will not get opened in month three. Tone matters more than most feature lists admit.

How do you compare price fairly?

Subscriptions come in weekly, monthly and yearly flavors, which makes sticker prices hard to compare. Convert everything to a cost per month, and check what is free before paying anything. For GLPily, tracking is free, and PRO is $5.99 a week, $12.99 a month or $59.99 a year. For other apps, check the current price on the store page in your country, since prices change and vary by region. Our guide to comparing GLP-1 app pricing and free trials goes deeper.

And remember: uninstalling an app does not cancel a subscription. Cancel through Apple or Google:

• iPhone: Settings → [your name] → Subscriptions.
• Android: Google Play subscriptions page (play.google.com/store/account/subscriptions).

What should break a tie?

If two apps score within a few points, ask:

1. Which one did I open without being reminded?
2. Which export would I rather hand my prescriber?
3. Which privacy policy answered my questions in plain words?

Then delete the others properly: export anything you want to keep, cancel trials, and use the in-app delete account option rather than just uninstalling.

What this test cannot tell you

A one-week test does not show how an app handles months of data, how support responds to a problem, or how often features change. It also cannot tell you anything about your treatment. No tracker should be choosing your dose or replacing your prescriber; our post on where the line sits between an app and your clinician spells that out.

Common questions

Is GLPily better than Shotsy or MeAgain?

We make GLPily, so we are the wrong people to declare a winner. Each app has different strengths, which our best GLP-1 tracker apps roundup summarizes. Run the seven-day test and let your own scorecard decide.

Can I move my data from one tracker to another?

Sometimes, if the old app exports raw data (like a CSV) and the new one can import it. Often you will start fresh and keep the old export as a record.

Do I need to test three apps?

No. Two is plenty for most people. Three is useful if you are torn between very different styles, like a simple shot log versus an all-in-one tracker.

Is it safe to log the same dose in several apps?

Logging the same real dose in several trackers is fine for comparison. Just make sure you take your medicine only as prescribed and that any reminders you keep after the test come from one app, so you do not get confused about shot day.
