Injectly alternative: no subscription, and iOS 13 support

Start with what Injectly does better

Most pages like this bury the concessions at the bottom. Here they belong at the top, because there are several and they are substantial.

No subscription. Injectly's App Store description says it plainly: no ads, no subscription, no tracking. Pinned is free for your first compound with no time limit, but unlimited compounds, the full calculator, advanced scheduling and export are a paid tier. On price alone, Injectly wins.

iOS 13.0. That is the lowest floor in this comparison set by five major releases, and Pinned's is 18.0. If your phone is more than a few years old, Injectly is available to you and Pinned simply is not.

Local by default, sync if you want it. No account is needed to log injections, set reminders and view history. A free account adds cross-device sync and advanced scheduling. Pinned has no account either — but it also has no sync at all, so Injectly offers the same privacy default plus an option Pinned cannot match.

The numbers, as of 30 July 2026

The price row reflects what Apple's listing data records for both apps. Injectly's own description states it has no subscription, which is the stronger claim and the one worth checking on its current listing before you decide.

Where Pinned's weight sits: before the log entry

Injectly's logging model starts at the point where you know the amount: dose, medication, date, time, route and site. That is the right model for prescriptions and pre-filled products, where the amount is a given.

Pinned puts most of its weight one step earlier. A vial of lyophilised powder has no dose until you decide how much bacteriostatic water goes in, and the answer to 'how many units do I draw' falls out of that decision rather than being printed anywhere. Pinned's calculator runs both directions — diluent volume to syringe units, or a target unit count back to the dilution — and keeps concentration, remaining volume and discard date attached to each vial so the number does not drift from the thing it describes.

If everything you log arrives ready to inject, that machinery is dead weight and you should not pay for it.

Two different ideas of what 'insight' means

Injectly's headline analytic feature is a serum concentration dashboard: for supported medications it estimates current and projected levels from your logged history and weight, shows how close you are to peak and how much of the dose remains active, and exposes pharmacokinetic detail behind it. That is ambitious work and clearly the centrepiece of the product.

Pinned deliberately models nothing. It records weight, bloodwork and quality-of-life markers, charts them against the doses you logged, and exports the lot as CSV or PDF. It will not estimate what is in your system, because that is a step from record-keeping toward inference, and Pinned's Terms put it on the record-keeping side of that line.

Which of those you want is a genuine preference, not a quality difference.

Which to pick

Pick Injectly if you want a free app with no subscription, if your phone cannot run iOS 18, if you want optional cross-device sync, or if modelled concentration curves are the feature you are actually shopping for.

Pick Pinned if reconstitution and unit arithmetic is the problem you need solved, if you want TRT and HRT in the same ledger as peptides and GLP-1s, or if you want the app in Dutch, French or German. On the other axes, Injectly is ahead, and this page is not going to pretend it is not.

FAQ

Is Pinned free like Injectly?

Not in the same way. Pinned is free to download and free for your first compound with no time limit, but unlimited compounds, the full calculator, advanced scheduling and export require Pinned Pro. Injectly's listing states it has no subscription at all.

Which app supports older iPhones?

Injectly, by a wide margin — iOS 13.0 against Pinned's 18.0 as of 30 July 2026. It is the widest device support in this comparison set. If your device cannot run iOS 18, Pinned is not an option.

Does Pinned estimate my current levels?

No. Injectly's listing describes a serum concentration dashboard with projected levels and percent-of-peak. Pinned does no modelling of any kind — it records what you entered and does arithmetic on it, nothing predictive.

Do both apps work without an account?

Yes. Injectly needs no account for logging, reminders and history, with an optional free account for sync and advanced scheduling. Pinned has no account option at all, which means no sync and no cloud backup — the record lives on the device behind an optional Face ID lock.

What does Pinned do that Injectly's listing does not describe?

Reconstitution and unit conversion working in both directions, per-vial concentration, remaining volume and discard dates, bloodwork and quality-of-life markers charted against doses, CSV and PDF export from inside the app, and an interface in English, Dutch, French and German.
