StackLogR vs Shotsy: Different Tools for Overlapping Jobs

This one isn't a clean head-to-head, and it's worth saying that up front. Shotsy is a GLP-1 tracker, full stop — built for a weekly Ozempic, Wegovy, Mounjaro, or Zepbound shot, and it's one of the most established apps in the injection-tracking space, with about 33,000 iOS ratings behind it. StackLogR is a broader injectable-protocol logger: GLP-1 alongside peptides, TRT, and HRT, all in one schedule, free and fully on-device on both iOS and Android. If your protocol starts and ends with a single GLP-1 medication, Shotsy has a real head start. If it doesn't, that's the gap this post is about.

StackLogR is our app, so read this knowing who wrote it — we've tried to keep every factual claim verifiable and to say plainly where Shotsy is the better pick.

Last verified October 5, 2026, against Shotsy's live App Store and Google Play listings and its privacy policy.

The short version

Pick Shotsy if: a GLP-1 medication is the only thing you're tracking, you want the most reviewed and polished app in the category, and — especially on iOS — you want a privacy story that's already excellent without a third-party account.

Pick StackLogR if: you're tracking a GLP-1 alongside peptides, TRT, or HRT and don't want two separate logs, you want the whole thing free, or you want the exact same on-device privacy on Android that Shotsy currently only delivers on iOS.

StackLogR is pre-launch — it's an early-access waitlist at stacklogr.com, not a live App Store or Google Play listing yet. That's the honest trade against Shotsy's years of reviews, and it's worth weighing plainly rather than glossing over.

At a glance

Where Shotsy wins

Credit where it's due — Shotsy earns its place as the default GLP-1 tracker for a lot of people:

• The track record. About 33,000 App Store ratings at 4.8 stars, plus 100K+ downloads and about 12,000 reviews at 4.7 stars on Google Play — one of the biggest apps in the injection-tracking space, on both platforms.
• Purpose-built focus. GLP-1 scheduling, injection-site rotation, and weight and side-effect tracking are the whole product, not a corner of a broader tool — a genuine advantage if a GLP-1 is truly the only thing you're logging.
• A polished, mature interface. Years of iteration show. This isn't a new app finding its footing.
• A genuinely strong iOS privacy story. On iOS, Shotsy keeps data in local storage synced through the user's own private iCloud, asks for no account, and its App Store privacy label reads “Data Linked to You: None” (Health & Fitness, Usage, and Diagnostics data are collected but not linked to identity). That's a real, well-earned claim, not a policy line.

If a GLP-1 is the only thing on your schedule and you're on an iPhone specifically, Shotsy is a strong default — plainly.

Where StackLogR wins

• One schedule instead of two apps. Shotsy is built around GLP-1 medications; its listings don't mention peptides, TRT, or HRT. StackLogR tracks all of those in one place, so a GLP-1 alongside another compound doesn't mean splitting your routine across two logs.
• StackLogR is the only peptide tracker that's fully on-device on both iOS and Android — free, with no account.
• Free, with no tiers. Shotsy's free version is real, but both stores list paid options, up to $19.99/month or $59.99/year on the App Store. StackLogR has no paywall for logging.
• The same privacy on Android as on iOS. Shotsy's strong privacy story is an iOS story — on Android, it uses Google Sign-In and Firebase, and its Play data-safety section discloses sharing crash logs, diagnostics, and app interactions with third parties for analytics. StackLogR is identical on both platforms: on-device, no account, no cloud, no third-party sharing disclosure to make in the first place.
• Vial inventory. StackLogR tracks vial and sealed stock with beyond-use-date awareness and warns before you run low — not a stated feature of Shotsy's listings. (Both apps handle injection-site rotation.)
• An estimated-active-amount chart and a compound guide. A half-life-based chart (an educational tracking aid, not a lab result) and a 100+ entry compound guide that never lists dose amounts, by policy.

The honest counterweight: StackLogR is pre-launch, with a waitlist instead of a store listing and no review history to point to yet. That's the real cost of being newer, and it's worth weighing against everything above.

Pricing

Shotsy is free to download, and its website says most features are free. Its App Store listing shows paid options at $9.99–$19.99 a month or $39.99–$59.99 a year; Google Play lists $12.99–$39.99 per item. Where exactly the free version ends isn't spelled out on the listings. StackLogR is free during early access — no subscription tiers, no paywalled logging, though pricing may look different once it's out of early access. Neither app has published a discount or lifetime option in its current listing.

Privacy and your data

This is where the two apps genuinely diverge, and Shotsy's story isn't one thing — it splits by platform, so it deserves a fair, specific answer rather than a single line.

On iOS, Shotsy is strong. Data stays in local storage and syncs through the user's own private iCloud — not a third-party server. There's no account required to use the app, and its App Store privacy label reads “Data Linked to You: None.” (Health & Fitness, Usage, and Diagnostics data are collected but not linked back to identity.) That's a legitimately good privacy posture, and we're not going to pretend otherwise just because it's a competitor's.

On Android, Shotsy is a different app, privacy-wise. Its privacy policy says the Android app requires Google Sign-In and stores your data in Google Firebase so it can sync and be recovered. Its Google Play data-safety section lists health info, email address, and device IDs among the data collected, and discloses sharing crash logs, diagnostics, and app interactions with third parties for analytics. (To be fair, the policy also says health entries aren't sent to its analytics and attribution tools.) That's a meaningfully different arrangement than the iOS version, even though it's the same product name.

StackLogR doesn't have that split. It's fully on-device — no account, no cloud sync, no server — on both iOS and Android, identically. There's no better version depending on which phone you own. That consistency is the specific thing StackLogR is built around, and it's the clearest place it separates from Shotsy rather than just competing on price.

Which one should you pick?

• You only track a GLP-1, you're on an iPhone, and you want the most established, polished app in the category: Shotsy. Its iOS privacy story is genuinely strong, and the review base speaks for itself.
• You track a GLP-1 alongside peptides, TRT, or HRT and don't want a second app: StackLogR — that's the specific gap Shotsy's listings don't cover.
• You're on Android and want the same privacy guarantees you'd get on an iPhone: StackLogR, since Shotsy's Android privacy picture is different from its iOS one.
• You don't want a subscription: StackLogR is free with no paywalled logging; Shotsy lists paid options on both stores.
• You want years of reviews and a mature, battle-tested app over a newer one: Shotsy, honestly — StackLogR is pre-launch and hasn't built that track record yet.

FAQ

Is Shotsy free?

It's free to download, and Shotsy's website says most features are free. Both stores also list paid options: $9.99–$19.99 a month or $39.99–$59.99 a year on the App Store, and $12.99–$39.99 per item on Google Play.

Does Shotsy track peptides?

Not as a stated feature. Shotsy is built for GLP-1 medications — Ozempic, Wegovy, Mounjaro, Zepbound, and similar. Its iOS app now lets you add custom medications, but neither store listing mentions peptides, TRT, or HRT. StackLogR's compound guide covers all of those alongside GLP-1s in one app.

Is Shotsy available on Android?

Yes. Shotsy runs on both iOS and Android, with about 33,000 iOS ratings (4.8 stars) and about 12,000 reviews on Google Play (4.7 stars, 100K+ downloads). The privacy setup differs by platform, though — see the privacy section above.

Which is more private, StackLogR or Shotsy?

It depends on the platform for Shotsy. On iOS, Shotsy is genuinely strong — local storage synced through the user's own iCloud, no account. On Android, it requires Google Sign-In and stores data in Firebase, and its Play data-safety section discloses sharing crash logs, diagnostics, and app interactions with third parties for analytics. StackLogR is on-device with no account on both iOS and Android, with no platform-by-platform difference.

Is StackLogR really free?

Yes, during early access — logging, reminders, inventory, site rotation, and the compound guide all come with no subscription and no paywalled tier.

Can I use StackLogR for GLP-1 tracking only?

Yes — a GLP-1 is just one entry in StackLogR's compound guide, and it logs the same way as anything else. But if a GLP-1 is genuinely the only thing you'll ever track, Shotsy's purpose-built focus and longer track record are real advantages worth weighing.

Is StackLogR available in the App Store or Google Play yet?

Not yet. StackLogR is pre-launch — it's an early-access waitlist at stacklogr.com rather than a live store listing, which also means it doesn't have a review history to point to the way Shotsy does.

Which app has more reviews?

Shotsy, by a wide margin — it has years of App Store and Google Play history behind it. StackLogR is new and pre-launch, with no review history yet. That's the clearest trade-off in this whole comparison.
