Spreadsheet or subscription app? The honest comparison
Updated: 2026-09
A spreadsheet costs nothing but does not remind you and does not convert currencies. An app does both but has to be maintained. With few subscriptions in one currency the spreadsheet is enough — the difference appears with deadlines and foreign currencies.
The honest answer to this question is not automatically the app. A spreadsheet is free, immediately available, entirely under your own control, and for many situations completely sufficient.
The difference shows in two places: with notice periods, which a spreadsheet does not remind you of, and with subscriptions in several currencies, whose total only comes out correctly in a spreadsheet with manual upkeep.
| Criterion | Innopulse | Alternative |
|---|---|---|
| Cost | Free | Depends on the plan chosen |
| Deadline reminders | Only via separate calendar entries | Automatic, before renewal |
| Multiple currencies | Manual conversion, goes stale quickly | Converted continuously, 25 currencies |
| Time zones | Not represented | Alerts in local time across 40 time zones |
| Data control | Entirely with you | With the provider, without bank access |
| Analysis | Only what you build yourself | Categories, trends, cost per use |
When an alternative is the better choice
You have few subscriptions, all in one currency.
You review your statements regularly anyway and never miss a deadline.
You do not want any further data leaving the house, even without bank access.
FAQ
What speaks for the spreadsheet?
Cost, full control and the fact that it is already there. With a manageable number in one currency it is a perfectly reasonable choice — we say so even when it argues against our product.
Where does a spreadsheet usually fail?
On notice periods. A spreadsheet does not remind you, and one missed deadline often commits twelve months.
Can you move from a spreadsheet to an app?
Yes, and it is the easiest capture there is, because the details are already collected.
What about data protection?
SubTracker requires no bank connection. You record the subscriptions yourself — more effort at the start, but no transaction data leaves your account.

Renewal alerts arrive in your local time — with international services that is the difference between in time and too late.
