What Subsy is for. Most subscription trackers tell you what you spend. Subsy tells you what each project costs. Tag a service with the apps that use it and its cost is split between them, so you can answer “what does this side project actually cost me a month?” — the question that decides whether it keeps earning its place.
Signing in
No passwords. Type your email and tap Email me a sign-in link. On the web you can also Continue with Google; the iPhone and iPad app uses the emailed code only, and reaches the same account either way. The email carries both a link and a short code — tap the link on the same device, or type the code into the field that appears. The code submits itself a moment after you stop typing.
There is nothing to set up afterwards. Your services, cards, apps and appearance choice are stored against your account and follow you to any device you sign in on.
Adding a service
Tap + Add service. If the service is one of the 43 Subsy already knows, tap its name at the top — that fills in the category and the dashboard, usage and billing links so you do not have to hunt them down later. Type in the filter box to narrow the list, or tap +31 more to see all of them.
Nothing is required except a name. Everything else can be filled in as you learn it, and the card gets more useful the more you tell it.
What each field means
| Field | What it is for |
|---|---|
| Tier / Plan | Which plan you are on — Pro, Team, Free. The thing you would change if you wanted to spend less. |
| Sub cost | The fixed recurring charge. |
| Additional charges | Whether there is usage or overage on top of the fixed cost, or none. |
| Average cost | What that usage typically adds. Sub cost + average cost is the headline figure on the card, so a metered service is not quietly understated. |
| Billing cycle | Monthly, yearly or one-off. Everything is normalised to a monthly figure for the totals, so annual and monthly plans can be compared honestly. |
| Renewal date | When it next charges. Inside 14 days the card turns red, which is your window to cancel before it bills rather than after. |
| Payment card | Which card pays for it. Pick from the cards you set up in Settings. |
| Payment note | For anything a card does not cover — billed via PayPal, on a client's account, invoiced annually. |
| Key limits | Only the two or three that actually constrain you: seats, CI minutes, build counts. Separate them with a middle dot. This is the field that tells you whether you are paying for headroom you never use. |
| Apps using it | The projects that depend on this service. This is what drives the cost split — see below. |
| Status | Active, trial or canceled. A canceled service stays on the list for the record but contributes nothing to the totals. |
The freshness ring
The circle on the left of each card is a number: days since you last saved that service. Subscription prices drift, plans get renamed and limits change, so a record you have not looked at in three months is a guess, not a fact. The ring empties as it ages.
You never set this by hand. Opening a service, checking it is still right and saving resets it to zero. Sorting by Least recently verified puts the most doubtful records at the top, which is the fastest way to work through them.
Finding things
The search box matches names, tiers and notes at once. Next to it: By app switches between the flat list and the cost breakdown, Name A–Z changes the sort, and All statuses hides trials or canceled services. The row of pills underneath filters to a single app.
Sort options worth knowing: Renewing soonest for what is about to bill, Cost high to low for where the money actually goes, and Least recently verified for what needs checking.
Spend by app
Tap By app and the list becomes a per-project breakdown. A service tagged to
three apps contributes a third of its monthly cost to each. The arithmetic is shown on every
line — GitHub (Team) ($19 ÷ 2) → $9.50 — so the number is
auditable rather than magic.
An even split is a deliberate simplification. It is not a usage-based allocation and does not pretend to be; it is a defensible way to stop shared infrastructure hiding from every project at once.
Each app also has a Feature ideas section, collapsed by default. It is a free-text scratchpad for the things you keep meaning to build — kept next to what that project costs, which is a useful place for them to sit together.
Payment cards
Settings → Payment cards. Add a card by issuer, last four or five digits and expiry, then point services at it. The value is in the questions it answers: which subscriptions die when this card expires next month, and what is still charging the card you thought you had retired.
Only the last four or five digits are ever stored. Enough to tell your cards apart, never enough to charge one. Subsy has no card number, no CVV and no connection to any payment network.
Apps and the architecture prompt
Settings → Apps is where you name your projects. Once services are tagged, the Copy button next to an app builds a prompt describing its whole stack — every service, tier, limit and cost, paid and free alike — ready to paste into Claude Code, Codex or any assistant and ask for an architecture diagram or a cost review.
It works because you already did the tagging. The prompt is only as good as the records behind it, which is another reason to keep the rings green.
Backup and restore
Settings → Backup. Export JSON writes a plain file you keep yourself; it is readable, diffable and belongs to you. Import JSON reads one back, asking whether to merge with what is already there or replace it.
Import restores services. Cards and apps are carried in the file but are not written back on import — re-enter those in Settings afterwards. Worth knowing before you rely on a backup as a full restore.
The format is identical in both apps. A file exported from the iPhone imports into the web app and the other way round.
Deleting your account
Settings → Account → Delete account, in either app. It removes every service, card, card photo, app, idea and setting, and the login itself, everywhere at once. It asks twice and cannot be undone, so export a backup first if you might want any of it again.
Two apps, one account
Subsy is an iPhone and iPad app and a web app at subsy.app/app, both on the same account and the same data. Sign in with the same email in either and you see the same services. The web app installs to a home screen or desktop like any other app.
Appearance and Default sort in Settings sync to your account, so a preference set on the phone follows you to the browser. Auto follows whatever your device is doing.
