Fit work around your life, not the other way around. Mornings, evenings, weekdays or weekends. Your call. TWO TYPES OF SHIFTS, SAME FLEXIBILITY Freelance shifts: be your own boss • You set your own hourly rate • Maximum flexibility • You handle your own tax and admin • Don't want to wait? Get paid within minutes of your shift Employed shifts: everything handled for you • No KvK, VAT ID or tax returns • We handle your admin • Pension, a safety net and surcharges, automatically • Paid every week Or mix them up. For every shift, the app shows what type it is, what you earn and what's arranged for you. No surprises. SAFETY NETS SOUND BORING, BUT ARE NICE Both types of shifts come with sick pay, accident cover and liability insurance. For freelance shifts, that's FreeSecurity, only at Temper. HOW IT WORKS 1. Download: set up your profile in minutes. 2. Pick: see the shift, the rate and the client. Before you apply. Not after. 3. Work: one tap. No interview for a 4-hour bar shift.

Verdict
The clearest difference is rating: Temper at 4.6 against MySirenum's 2.5. Temper also leads on update cadence (every 4 weeks vs every 3 months) and ratings volume (97 vs 4). MySirenum's advantage is review sentiment (41% vs 9%) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Temper holds the better App Store score, 4.6 against 2.5. That said, the two scores are not equally well evidenced: Temper has 97 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 41% of MySirenum's written reviews are positive against 9% of Temper's, so the app with the better star average is not the one people write more warmly about.
MySirenum ships an update every 3 months, Temper every 4 weeks. The most recent releases landed on November 1, 2026 and November 13, 2026 respectively.
